This post documents my participation in a hackathon 2 weeks ago. I started writing this a week ago and finished it now, so it's a little mixed. Scroll to the bottom for the final result!

Rowan reached out asking if I'm going to the hackathon, and I wasn't sure which one he meant. Although I submitted a project to the recent Gemini hackathon, it was more of an excuse to migrate an expensive GPT-based project ($100s per month) to Gemini (worse, but I had free credits). I never really join these things to actually compete, and there was no chance a project like that could win anyway. What's the opposite of a shoo-in? A shoo-out?

So it turns out Rowan meant the Mistral x a16z hackathon. This was more of a traditional "weekend crunch" type of hackathon. I felt like my days of pizza and redbull all-nighters are long in the past by at least a decade, but I thought it might be fun to check out that scene and work on something with Rowan and Nour. It also looked like a lot of people I know are going. So we applied and got accepted. It seems like this is another one where they only let seasoned developers in, as some of my less technical friends told me they did not get in.

Anyway, we rock up there with zero clue on what to build. Rowan wants to win, so is strategising on how we can optimise by the judging criteria, researching the background of the judges (that we know about), and using the sponsors' tech. I nabbed us a really nice corner in the "Monitor Room" and we spent a bit of time snacking and chatting to people. The monitors weren't that great for working (TV monitors, awful latency) but the area was nice.

Since my backup was a pair of XReal glasses, a lot of people approached me out of curiosity, and I spent a lot of time chatting about the ergonomics of it, instead of hacking. I also ran into friends I didn't know would be there: Martin (Krew CTO and winner of the Anthropic hackathon) was there, but not working on anything, just chilling. He intro'd me to some other people. Rod (AI professor / influencer, Cura advisor) was also there to document and filmed us with a small, really intriguing looking camera.

We eventually landed on gamifying drug discovery. I should caveat that what we planned to build (and eventually built) has very little scientific merit, but that's the goal of a hackathon; you're building for the sake of building and learning new tools etc. Roughly-speaking, we split up the work as follows: I built the model and some endpoints (and integrated a lib for visualising molecules), Nour did the heavy-lifting on frontend and deploying, and Rowan did product design, demo video, pitch, anything involving comms (including getting us SSH access to a server with a nice and roomy H100), and also integrated the Brave API to get info about a molecule (Brave was one of the sponsors).

You're probably wondering what we actually built though. Well, after some false starts around looking at protein folding, I did some quick research on drug discovery (aided by some coincidental prior knowledge I had about this space). There's a string format for representing molecules called SMILES which is pretty human-readable and pervasive. I downloaded a dataset of 16k drug molecules, and bodged together a model that will generate new ones. It's just multi-shot (no fine-tuning, even though the judges might have been looking for that, as I was pretty certain that would not improve the model at all) and some checking afterwards that the molecule is physically possible (I try 10 times to generate one per call, which is usually overkill). I also get some metadata from a government API about molecules.

On the H100, I ran one of those stable diffusion LORAs. It takes a diagram of a molecule (easy to generate from a SMILES string) and then does img2img on it. No prompt, so it usually dreams up a picture of glasses or jewellery. We thought this was kind of interesting, so left it in. We could sort of justify it as a mnemonic device for education.

Finally, I added another endpoint that takes two molecules and creates a new one out of the combination of the two. This was for the "synthesise" journey, and was inspired by those games where you combine elements to form new things.

Throughout the hackathon, we communicated over Discord, even though on the Saturday, Rowan and I sat next to each other. Nour was in Coventry throughout. It was actually easier to talk over Discord, even with Rowan, as it was a bit noisy there. Towards the end of Saturday, my age started to show and I decided to sleep in my own bed at home. Rowan stayed at the hackathon place, but we did do some work late into the night together remotely, while Nour was offline. The next day, I was quite busy, so Rowan and Nour tied up the rest of the work, while I only did some minor support with deployment (literally via SSH on my phone as I was out).

Finally, Rowan submitted our entry before getting some well-deserved rest. He put up some links to everything here, including the demo video.

Not long after the contest was over, they killed the H100 machines and seem to have invalidated some of the API keys also, so it looks like the app is also not quite working anymore, but overall it was quite fun! We did not end up winning (unsurprisingly) but I feel like I've achieved my own goals. Rowan and Nour are very driven builders who I enjoyed working with, and CodeNode is a great venue for this sort of thing. The next week, Rowan came over to my office to co-work and also dropped off some hackathon merch. I ended up passing on the merch to other people, as I felt a bit like I might be past my hackathon years now!

In April 2023, I came across this article and found it very inspiring. I had already been experimenting with ways of visualising a digital library with Shelfiecat. The writer used t-SNE to "flatten" a higher-dimensional coordinated space into 2D in a coherent way. He noticed that certain genres would cluster together spatially. I experimented with these sorts of techniques a lot during my PhD and find them very cool. I just really love this area of trying to make complicated things tangible to people in a way that allows us to manipulate them in new ways.

My use case was my thousands of bookmarks. I always felt overwhelmed by the task of trying to make sense of them. I might as well have not bookmarked them as they all just sat there in piles (e.g. my Inoreader "read later" list, my starred GitHub repos, my historic Pocket bookmarks, etc). I had built a database of text summaries of a thousand or so of these bookmarks using Url summariser, and vector embeddings of these that I dumped into a big CSV file, which at the time cost me approximately $5 of OpenAI usage. This might seem steep, but I think at the time nobody had access to GPT-4 yet, and the pricing also wasn't as low. I had also I accidentally had some full-length online books bookmarked, and my strategy of recursively summarising long text (e.g. YouTube transcripts) didn't have an upper limit, so I had some book summaries as well.

Anyway, I then proceeded to tinker with t-SNE and some basic clustering (using sklearn which is perfect for this sort of experimentation). I wanted to keep my data small until I found something that sort of works, as sometimes processing takes a while which isn't conducive to iterative experimentation! My first attempt was relatively disappointing:

Here, each dot is a bookmark. The red dots are not centroids like you would get from e.g. k-means clustering, but rather can be described as "the bookmark most representative of that cluster". I used BanditPAM for this, after reading about it via this HackerNews link, and thinking that it would be more beneficial for this use case.

I was using OpenAI's Ada-2 for embeddings, which outputs vectors with 1536 dimensions, and I figured the step from 1536 to 2 is too much for t-SNE to give anything useful. I thought that maybe I need to do some more clever dimensionality reduction techniques first (e.g. PCA) to get rid of the more useless dimensions first, before trying to visualise. This would also speed up processing as t-SNE does not scale well with number of dimensions. Reduced to 50, I started seeing some clusters form:

Then 10:

Then 5:

5 which wasn't much better than 10, so I stuck with 10. I figured my bookmarks weren't that varied anyway, so 10 dimensions are probably good enough to capture the variance of them. Probably the strongest component will be "how related to AI is this bookmark" and I expect to see a big AI cluster.

I then had a thought that maybe I should use truncated SVD instead of PCA, as that's better for sparse data, and I was picturing this space in my mind to really be quite sparse. The results looked a bit cleaner:

Now let's actually look at colouring these dots based on the cluster they're in. Remember that clustering and visualising are two separate things. So you can cluster and label before reducing dimensions for visualising. When I do the clustering over 1500+ dimensions, and colour them based on label, the visualisation is quite pointless:

When I reduce the dimensions first, then we get some clear segments, but the actual quality of the labelling is likely not as good:

And as expected, no dimension reduction at all gives complete chaos:

I started looking at the actual content of the clusters and came to a stark realisation: this is not how I would organise these bookmarks at all. Sure, the clusters were semantically related in some sense, but I did not want an AI learning resource to be grouped with an AI tool. In fact, did I want a top-level category to be "learning resources" and then that to be broken down by topic? Or did I want the topic "AI" to be top-level and then broken down into "learning resources", "tools", etc.

I realised I hadn't actually thought that much about what I wanted out of this (and this is also the main reason why I limited the scope of Machete to just bookmarks of products/tools). I realised that I would first need to define that, then probably look at other forms of clustering.

I started a fresh notebook, and ignored the page summaries. Instead, I took the page descriptions (from alt tags or title tags) which seemed in my case to be much more likely to say what the link is and not just what the content is about. This time using SentenceTransformer (all-MiniLM-L6-v2) as Ada-2 would not have been a good choice here, and frankly, was probably a bad choice before too.

I knew that I wanted any given leaf category (say, /products/tools/development/frontend/) shouldn't have more than 10 bookmarks or so. If it passes that threshold, maybe it's time to go another level deeper and further split up those leaves. This means that my hierarchy "tree" would not be very balanced, as I didn't want directories full of hundreds of bookmarks.

I started experimenting with Agglomerative Clustering, and visualising the results of that with a dendrogram:

Looking at the where bookmarks ended up, I still wasn't quite satisfied. Not to mention, there would need to be maybe some LLM passes to actually decide what the "directories" should be called. It was at this point that I thought that maybe I need to re-evaluate my approach. I was inadvertently conflating two separate problems:

1. Figuring out a taxonomy tree of categories
2. Actually sending bookmarks down the correct branches of that tree

There's a hidden third problem as well: potentially adjusting the tree every time you add a new bookmark. E.g. what if I suddenly started a fishing hobby? My historical bookmarks won't have that as a category.

I thought that perhaps (1) isn't strictly something I need to automate. I could just go through the one-time pain of skimming through my bookmarks and trying to come up with a relatively ok categorisation schema (that I could always readjust later) maybe based on some existing system like Johnny•Decimal. I could also ask GPT to come up with a sane structure given a sample of files.

As time went on, I also started to spot some auto-categorisers in the wild for messy filesystems that do the GPT prompting thing, and then also ask GPT where the files should go, then moves them there. Most notably, this.

That seems to me so much easier and reliable! So my next approach is probably going to be having each bookmark use GPT as a sort of "travel guide" in how it propagates the tree. "I'm a bookmark about X, which one of these folders should I move myself into next?" over and over until it reaches the final level. And when the directory gets too big, we ask GPT to divide it into two.

The LLM hammer seems to maybe win out here -- subject to further experimentation!

Chat as an interface has always been something I thought about a lot. After all, it's a close analogue to spoken conversation, our most natural form of communication.

The most basic chat interface is an input box and a chronological history of messages, so you can follow the conversation. Messages are often augmented with emojis etc to fill in the gaps for intonation and body language. If you need higher communication bandwidth, voice messages do it sometimes too. Advantages over face-to-face conversation is that text-based conversations have the option of being asynchronous and much longer-lived, potentially even pen-pal style correspondences.

Group conversations

The moment you start thinking about group conversations, some problems begin to be unearthed. One problem is it can get quite crowded, as you're sharing a linear chat history. It's hard to follow multiple threads of conversation that have been flattened into one, when in real life conversations can branch off and diverge.

This is a problem in video conferences too. While at a social event, groups naturally divide into smaller clusters of people in their own bubble of conversation, this has to be done explicitly in video conferences through breakout rooms and similar mechanics. Otherwise all the attention and spotlight is aimed at the person currently talking, which can throw off the dynamics.

I first noticed this phenomenon when I was running the Duolingo German language events in London. It's already common for people who don't know the language well to be shy about speaking up, but when covid started and we switched to Zoom, it was very easy for whomever is speaking to get stage fright, even if they're not normally shy. What then ends up happening is that two or three people will engage in conversation while the rest watch, unless the host (me in that case) takes control of the group dynamics. This was much easier to do in-person, especially where I could see the person's face and gauge how comfortable they are, so I don't put them on the spot (e.g. by bringing them into the conversation with simple yes/no questions).

Attempts at solutions

Anyway, during covid I became quite interested in products that try to solve these problems by capturing aspects of real-life communication through product design. I remember imagining a 2D virtual environment with spatial audio in the context of my PhD research. It turned out somebody was already building something similar: a fellow named Almas, and I remember having a call with him about SpatialChat (a conversation full of lovely StarCraft metaphors). This was an environment that allowed you to replicate the act of physically leaving a huddle and moving to a different cluster to talk. You could only be heard by those in "earshot".

A 2D game called Manyland did something similar with text-only, where text would appear above the head of your character as you were typing. This created interesting new dynamics and etiquette around "interrupting" each other, as well as things like awkward silences, which don't exist when you're waiting for someone to type. There was even an odd fashion around typing speed at one point.

Interestingly, you're not occupying space in the chat log by chatting; you're filling the space above your head, so you just need to find a good place to perch. Two people can respond to the same thing at the same time. However, one person can't quite multi-task their responses / threads without jumping back and forth between people, but after all that's how it works in real life too, no?

Reply chains and threads

I won't go over the history of different chat platforms and apps, but we've seen a lot of patterns that try and create some structure around communication, here in order from more ephemeral to less ephemeral:

• Quoting a message to reply to inline
• Ad-hoc threads that create a separated chat log
• More permanent threads akin to forums
• Permanent "topic" channels

I like to imagine conversations as trees, where branches can sprout and end just as fast. Have you ever been in an argument where someone rattles off a bunch of bad points, but you can only counter them in series? Each of your responses may in turn trigger several additional responses, and you get this exponentially growing tree and eventually you're writing essays dismantling every point one by one.

In real life, it's often hard to remember everything that was said, so you focus on just the most important parts. Or you deliberately prune the branches to the conversation doesn't become unwieldy. Some people like to muddy the waters and go off topic and it's up to you to steer the conversation back to the main trunk.

But not everything is a debate. A friend of mine figured that this tree, in 2D, ought to be the way to hold conversations. Big big internet conversations (he used social media as an example) are all adding nodes to far off branches of a huge tree. I quite like that picture. It would certainly allow for conversations to happen in parallel at the same time as you can hop back and forth between branches.

ChatGPT and the history tree

ChatGPT made the choice that chats should be linear, but you can start a new chat with a new instance of the AI at any time, and go back to old chats through the history tab. This seems to make sense for chatting with an AI assistant, but an anti-pattern emerges...

Have you ever gone down a conversation with ChatGPT only to realise that it's dug itself into a hole, so you scroll up to just after the last "good" message and edit the message to create a new, better timeline? I do this a lot, and it reminded me of undo/redo in text editors.

Undo and redo are normally linear, and if you go back in time and make a change, suddenly the old "future" is no longer accessible to you. We've all done it where we accidentally typed something after pressing undo a bunch of times to check a past version, losing our work.

Someone made a plugin for vim that allows you to navigate a tree of timelines that you create by undo-ing, sort of like automatic git branching and checkout. I feel like this ought to be a UI for interacting with ChatGPT too! Already this is being used for better responses and I feel like there must have been attempts at creating a UI like this, but I haven't seen one that does this elegantly.

Conclusion

This has been kind of a stream of though post, inspired by my post on resetting my AI assistant's chat memory, so I'm not entirely sure what the point I'm trying to make is. I think I'm mainly trying to narrow down the ergonomics of an ideal chat interface or chat in a virtual environment.

I think you would probably have some set of "seed" nodes -- the stem cells to your threads -- which are defined by individuals (i.e. DMs), or groups with a commonality, or topics. These would somehow all capture the nuances of real-life communication, but improve on that with the ability to optionally create ephemeral threads out of reply branches. I'm not yet sure what the UI would physically look like though.

Sentinel, my AI personal assistant has evolved a bit since I last wrote about him. I realised I hadn't written about that project in a while when it came up in conversation and the latest reference I had was from ages ago. The node-red logic looks like this now:

1. Every morning he sends me a message (in the future this will be a status report summary). The goal of this was to mainly make sure the WhatsApp integration still works, since at the time it would crap out every once in a while and I wouldn't realise.
2. I have an endpoint for arbitrary messages, which is simply a URL with a text GET parameter. I've sprinkled these around various projects, as it helps to have certain kind of monitoring straight to my chats.
3. He's plugged in to GPT-4-turbo now, so I usually just ask him questions instead of going all the way to ChatGPT. He can remember previous messages, until I explicitly ask him to forget. This is the equivalent of "New Chat" on ChatGPT and is controlled with the functions API via natural language, like the list-adder function which I already had before ("add Harry Potter to my movies list").

As he's diverged from simply being an interface to my smart home stuff, as well as amarbot which is meant to replace me, I decided to start a new project log just for Sentinel-related posts.

Edit: this post inspired me to write more at length about chat as an interface here.

In UI design, Skeuomorphism is where UI elements look like their physical counterparts. For example, a button might have highlights/shadows, you might adjust time through slot-machine-like dials, or hear a shutter sound when you take a photo. I quite like skeuomorphic design.

I pay special attention to icons. My younger sister is young enough to have never used a floppy disk and therefore only knows this symbol 💾 to mean "save" but not why. You see it everywhere: icons (like a phone handset), language (like an "inbox"), and other tools (like the dodge and burn tools in photo editors, which stem from physical retouching on film).

Sometimes, words have gone through several layers of this, where they're borrowed over and over again. For me, one area where I see this a lot is in networks. In the days of radio and analogue electronics, we got a lot of new words that were borrowed from other things that people were already familiar with. Once computer networks came along, suddenly "bandwidth" adopted a different meaning.

The key here is this idea of familiarity. When something is new, it needs to be rooted in something old, in order for people to be able to embrace it, let alone understand it. Once they do, only then do you see design trends cut the fat (for example, the shiny Web 2.0 style made way for the more flat design we have today). If a time traveller from 20 years ago were to visit, of course they would find modern design and affordances confusing.

Take this a step further however: what about the things that never had a physical counterpart or couldn't quite be connected to one? Well, it seems we latch on to the closest available concept or symbol! For example, what exactly is "the cloud"? It never substituted water vapour in the sky; it was something new. Why is this ☰ the symbol for a hamburger menu? Because it sort of looks like items in a menu. Not to mention, why did we call it a hamburger menu? Because the symbol sort of looks like a hamburger.^[1]

Anyway, why do I bring all this up? Because I noticed new words and icons showing up in the AI space, as AI is becoming more ubiquitous. AI assistance built into tools are becoming "copilots". The symbol for "apply AI" is becoming magic sparkles that look a bit like this ✨. I find this very interesting -- people seem to not quite have a previous concept to connect AI to other than "magic", and the robot emoji might be a little too intimidating 🤖 (maybe I should change the Amarbot triggering reaction to sparkles instead).

A couple days ago, this was trending on HackerNews, and sparked some conversation in my circles. As you might know, I have some interest in this space. It seemed to have some overlap with gather.town, a 2D virtual environment for work. This category really took off during covid. This product in particular has some big name backers (though not a16z ironically enough).

This got me thinking... AI agents would truly be first-class citizens in environments like these. You would interact with them the same way you interact with a human colleague. You could tell them "go tell Bob to have the reports ready by 2pm" and the agent would walk over to Bob's virtual desk, and tell them using the same chat / voice interface that a human would use.

How would agents interact with the outside world? LLMs already have an understanding of human concepts baked in. Why hack a language model to execute code (Code Interpreter) when you could use the same skeuomorphism that humans are good at, in an environment like this? If there's a big red button in the corner of your virtual office called "server restart button", a human as well as an AI agent can easily interact with that. Neither may ever know that this magic button does something in a parallel universe.

It might be some ways off before we're all working out of the metaverse, but I believe that the only way for that to happen is if it becomes more ergonomic than real life. It just so happens that this is great for humans as well as AI agents! There are already a class of tools that make you more productive in AR/VR than on a normal monitor (think 3D CAD). However when it comes to day-to-day working, organising your thoughts, communicating, etc, we still have some ways to go. To cross that bridge, we most likely need to embrace skeuomorphic design in the first instance.

What might that look like? Certainly storing information in space. Your desk top (and I don't mean "desktop", I mean literally the surface of your desk) can go 3D, and you can perhaps visualise directory trees in ways you couldn't before. Humans have excellent spatial reasoning (and memory) as my friend working on virtual mind palaces will tell you.

You could of course have physical objects map 1:1 to their virtual counterparts, e.g. you could see a server rack that represents your actual servers. However, instead of red and green dots on a dashboard, maybe the server can catch on literal fire if it's unhealthy? That's one way to receive information and monitor systems! A human as well as an AI agent can understand that fire is bad. Similarly, interactions with things can be physical, e.g. maybe you toss a book into a virtual basket, which orders a physical version of it. Maybe uploading a photo to the cloud is an actual photo flying up to a cloud?

Or maybe this virtual world becomes another layer for AI (think Black Mirror "White Christmas" episode), where humans only chat with a single representative that supervises all these virtual objects/agents, and talks in the human's ear? Humans dodge the metaverse apocalypse and can live in the real world like Humane wants?

Humans are social creatures and great at interacting with other humans. Sure, they can learn to drive a car, and no longer have to think about the individual actions, rather the intent, but nothing is more natural than conversation. LLMs are great at conversation too of course (it's in the name) and validates a belief that I've had for a long time that conversation may be the most widely applicable and ergonomic interaction interface.

What if my server was a person in my virtual workspace? A member of my team like any other? What if it cried if server health was bad? What if it explained to me what's wrong instead of me trawling through logs on the command line? I'm not sure what to call this. Is this reverse-skeuomorphism? Skeuomorphic datavis?

I might have a fleet of AI coworkers, each specialised in some way, or representing something. Already Sentinel is a personification of my smart home systems. Is this the beginning of an exocortex? Is there a day where I can simply utter my desires and an army of agents communicate with each other and interact with the world to make these a reality?

(Most) humans are great at reading faces (human faces that is, the same way Zebras can tell each other apart). This concept was explored in data visualisation before, via Chernoff faces. There are reasons why it didn't catch on but I find it very interesting. I was first introduced to this concept by the sci-fi novel Blindsight. In it, a vampire visualises statistical data through an array of tortured faces, as their brains in this story are excellent at seeing the nuance in that. You can read the whole novel for free online like other Peter Watts novels, but I'll leave the quote here for good measure:

A sea of tortured faces, rotating in slow orbits around my vampire commander.

"My God, what is this?"

"Statistics." Sarasti seemed focused on a flayed Asian child. "Rorschach's growth allometry over a two-week period."

"They're faces…"

He nodded, turning his attention to a woman with no eyes. "Skull diameter scales to total mass. Mandible length scales to EM transparency at one Angstrom. One hundred thirteen facial dimensions, each presenting a different variable. Principle-component combinations present as multifeature aspect ratios." He turned to face me, his naked gleaming eyes just slightly sidecast. "You'd be surprised how much gray matter is dedicated to the analysis of facial imagery. Shame to waste it on anything as—counterintuitive as residual plots or contingency tables."

I felt my jaw clenching. "And the expressions? What do they represent?"

"Software customizes output for user."

There are so many parallels between language and programming. For example, Toki Pona (a spoken language with a vocabulary of only 120 words) is like the RISC of linguistics. You need to compose more words together to convey the the same meaning, but it's quite elegant how you can still do that with so few words. It seems like languages don't need that large a vocabulary to be "Turing complete" and able to express any idea. Or maybe because language and thought are so tightly coupled, we're just not able to even conceive of ideas that we don't have the linguistic tools to express in the first place.

You can create subroutines, functions, macros in a program. You can reuse the same code at a higher level of abstraction. Similarly, we can invent new words and symbols that carry a lot more meaning, at the cost of making our language more terse. A language like Toki Pona is verbose because ideas are expressed from elementary building blocks and are context-dependent.

I imagine a day where abstractions layered on top of abstractions disconnect us from the underlying magic. You see a symbol like the Bluetooth icon and it has no other meaning to you except Bluetooth. In your virtual world, you interact with curious artefacts that have no bearing on your reality. You read arcane symbols as if they were ancient runes. You cast spells by speaking commands to underlings and ambient listeners that understand what you mean. Somewhere along the way, we can no longer explain how this has become a reality; how the effects we see actually connect to the ones and zeros firing. Is that not magic? ✨

I made some small changes to the Miniverse project. It still feels a bit boring, but I'm trying different experiments, and I think I want to try a different strategy, similar to Voyager for Minecraft. Instead of putting all the responsibility on the LLM to decide what to do each step of the simulation, I want to instead allow it to modify its own imperative code to change its behaviour when need be. Unlike the evolutionary algos of old, this would be like intelligent design, except the intelligence is the LLM, rather than the LLM controlling the agents directly.

Before I do this however, I decided to clean the codebase up a little, and make the GitHub repo public, as multiple people have asked me for the code. It could use a bit more cleanup and documentation, but at least there's a separation into files now, rather than my original approach of letting the code flow through me into a single file:

I also added some more UI to the front end so you can see when someone's talking and what they're saying, and some quality of life changes, like loading spinners when things are loading.

There's still a lot that I can try here, and the code will probably shift drastically as I do, but feel free to use any of it. You need to set the OPENAI_KEY environment variable and the fly.io config is available too if you want to deploy there (which I'm doing). The main area of interest is probably NPC.js which is where the NPC prompt is built up.

Amarbot no longer has a WhatsApp number. This number now belongs to Sentinel, the custodian of Sanctum.

This number was originally wired up directly to Sanctum functions, as well as Amarbot's brain; a fine-tuned GPT-J model trained on my chat history. Since this wiring was through Matrix it became cumbersome to have to use multiple Matrix bridges for various WhatsApp instances. I eventually decided use that model on my actual personal number instead, which left Amarbot's WhatsApp number free.

Whenever Amarbot responds on my behalf, there's a small disclaimer. This is to make it obvious to other people whether it's actually me responding or not, but also so when I retrain, I can filter out artificial messages from the training data.

I mentioned recently that I've been using OpenAI's new functions API in the context of personal automation, which is something I've explored before without the API. The idea is that this tech can short-circuit going from a natural language command, to an actuation, with nothing else needed in the middle.

The natural language command can come from speech, or text chat, but almost universally, we're using conversation as an interface, which is probably the most natural medium for complex human interaction. I decided to use chat in the first instance.

Introducing: Sentinel, the custodian of Sanctum.

No longer does Sanctum process commands directly, but rather is under the purview of Sentinel. If I get early access to Lakera (the creators of Gandalf), he would also certainly make my setup far more secure than it currently is.

I repurposed the WhatsApp number that originally belonged to Amarbot. Why WhatsApp rather than Matrix? So others can more easily message him -- he's not just my direct assistant, but like a personal secretary too, so e.g. people can ask him for info if/when I'm busy. The downside is that he can't hang out with the other Matrix bots in my Neurodrome channel.

A set of WhatsApp nodes for Node-RED were recently published that behave similarly to the main Matrix bridge for WhatsApp, without all the extra Matrix stuff in the way, so I used that to connect Sentinel to my existing setup directly. The flow so far looks like this:

The two main branches are for messages that are either from me, or from others. When they're from others, their name and relationship to me are injected into the prompt (this is currently just a huge array that I hard-coded manually into the function node). When it's me, the prompt is given a set of functions that it can invoke.

If it decides that a function should be invoked, the switchResponse node redirects the message to the right place. So far, there are only three possible outcomes: (1) doing nothing, (2) adding information to a list, and (3) responding normally like ChatGPT. I therefore sometimes use Sentinel as a quicker way to ask ChatGPT one-shot questions.

The addToList function is defined like this:

{
	name: "addToList",
	description: "Adds a string to a list",
	parameters: {
		type: "object",
		properties: {

}

I don't actually have a groceries list, but for the other two (movies and books), my current workflow for noting down a movie to watch or a book to read is usually opening the Obsidian app on my phone and actually adding a bullet point to a text file note. This is hardly as smooth as texting Sentinel "Add Succession to my movies list". Of course, Sentinel is quite smart, so I could also say "I want to watch the first Harry Potter movie" and he responds "Added "Harry Potter and the Sorcerer's Stone" to the movies list!".

The actual code for adding these items to my lists is by literally appending a bullet point to their respective files (I have endpoints for this) which are synced to all my devices via the excellent Syncthing. In the future, I could probably make this fancier, e.g. query information about the movie/book and include a poster/cover and metadata, and also potentially publish these lists.

I've been experimenting with OpenAI's new functions API recently, mostly in the context of personal automation, which is something I've explored before without the API (more on that in the future). However, something else I thought might be interesting would be to give NPCs in a virtual world a more robust brain, like the recent Stanford paper. This came in part from the thinking from yesterday's post.

The Stanford approach had many layers of complexity and they were attempting to create something that is close to real human behaviour. I'm less interested in that, and would instead like to design an environment with much higher constraints based on simple rules. I think finding the right balance there leads to the most interesting emergent results.

So my first goal was to create a very tightly scoped environment. I decided to start with a 32x32 grid, made of emojis, with 5 agents randomly spawned. The edge of the grid is made of walls so they don't fall off.

Agents after they had walked towards each other for a chat

When I was originally scoping this out, I thought I would add mechanisms for interacting with items too. These items could be summoned in some way perhaps. I built a small API for getting the nearest emoji to item text as well, which is still up at e.g. https://gen.amar.io/emoji/green apple (replace "green apple" with whatever). It also caches the emojis so overall not expensive to run.

I also explored various models for generating emoji-like images, for the more fantastical items, and landed on emoji diffusion. It was at this point that I quickly realised I'm losing control of the scope, and decided to focus on NPCs only, and no items.

Each simulation step (tick) would iterate over all agents and compute their actions. I planned for these possible actions:

• Do nothing
• Step forward
• Step back
• Step left
• Step right
• Say X
• Remember X (doesn’t end round)

I wanted the response from OpenAI to only be function calls, which unfortunately you can't control, so I had to add to the prompt You MUST perform a single function in response to the above information. If I get any bad response, we either retry or fall back to "do nothing", depending.

The prompt contained some basic info, a goal, the agent's surroundings, the agent's memory (a truncated list of "facts"), and information on events of the past round. I found that I couldn't quite rely on OpenAI to make good choices, so I selectively build the list of an agent's capabilities on the fly each tick. E.g. if there's nobody in speaking distance, we don't even give the agent the ability to speak. If there's a wall ahead of the agent, we don't even give the agent the chance to step forward. And if the agent just spoke, they lose the ability to speak again for the following round or else they speak over each other.

I had a lot of little problems like that. Overall, the more complicated the prompt, the more off the rails it goes. Originally, I tried The message from God is: "Make friends" as I envisioned interaction from the user coming in the form of divine intervention. But then some of the agents tried speaking to God and such, so I replaced that with Your goal is: "Make friends", and later Your goal is: "Walk to someone and have interesting conversations" so they don't just walk randomly forever.

They would also feel compelled to try and remember a lot. Often the facts they remembered were quite useless, like the goal, or their current position. The memory was small, so I tried prompt engineering to force them to treat memory as more precious, but it didn't quite work. Similarly, they would sometimes go on endless loops remembering the same useless fact over and over. I originally had all information in their memory (like their name) but I didn't want them to forget their name, so put the permanent facts outside.

Eventually, I removed the remember action, because it really wasn't helping. They could have good conversations, but everything else seemed a bit stupid, like I might as well program it procedurally instead of with LLMs.

I did however focus a lot on having a very robust architecture for this project, and made all the different parts easy to build on. The server does the simulation (in the future, asynchronously, but today, through the "tick" button) and stores world state in a big JSON object that I write to disk so I can rewind through past states. There is no DB, we simply read/write from/to JSON files as the world state changes. The structure of the data is flexible enough that I don't need to modify the schemas, and it can remain pretty forwards-compatible as I make additions, so I can run the server off of older states and it picks up those states gracefully.

Anyway, I'll be experimenting some more and writing up more details on the different parts as they develop!

I love cracking hard problems. So it follows that I love CTFs, ARGs, even treasure hunts, and other puzzles of the sort.

I even tried my hand at creating these for other people. I'll talk about these more in the future, but one puzzle that I made came up in conversation, where I programmed a sage character in Manyland to give you hints for a key word that he confirms, which is needed for the next stage of the puzzle.

We were talking about how much more fun these puzzles can now be with the rise of LLMs. Back then, it was all quite procedural. But today, you could prompt an LLM to be the sage and not reveal the passphrase until the player has met certain conditions.

A week later my friend brought my attention to AI Gandalf. I LOVE this. I managed to make it through the main seven levels in around 20 minutes and get myself on the leaderboard, although my prompts weren't very creative. My friend had some much more creative prompts. If you haven't tried this, try it and let me know if you need any tips!

Now I'm stuck on the extra level 8 ("Gandalf the White"). This seems to be the ultra-hardened version that the developers have built from all the data they've gathered. I figured it must be possible, since there's a leaderboard, but it seems like they've actually been updating it on the fly whenever a new loophole is found.

It's driving me crazy! If anyone can come up with a solution, please give me a tip!

Ever since I discovered the Discord server for AI music generation, I knew I needed to train a model to make my voice a great singer. It took some figuring out, but now I'm having a lot of fun making myself sing every kind of song. I've tried dozens now, but here are some ones that are particularly notable or fun (I find it funniest when things glitch out especially around the high notes):

Some days ago, OpenAI released the code and models for Shap-E, which lets you do text-to-3D, and download a mesh you can use in any 3D software or for game development (rather than NeRFs with extra steps like previous models, and many papers that never released their code). This is very exciting, as the quality is reasonably good, and previously I would try to get that through various hacks.

There is already a HuggingFace space to try it, but no model on HuggingFace that you can easily use with their Inference API. You can fork the space and turn it into an API with some extra work, but I wasn't able to easily figure this out, and since running your own space is expensive anyway, I decided to take the easy way out and put a Flask server on top of OpenAI's existing code.

My server implementation is here. Since generating a new model only takes a couple seconds, I decided to design the interface as a "just-in-time" download link. You request /models/cat.ply, and if it's been generated before, it will download right away, but if not, then it's generated on the fly while the request is blocking.

I ran this on vast.ai, on an A10 instance, but I'm probably not going to keep it up for long as it's a bit expensive. I used the default pytorch image, and tweaked the config to expose the server on port 8081, which is a Docker port that vast.ai then maps to a port on the host. I added a proxy to that on my Model Compositor project which you can try here for free.

Dolly 2.0, a recently released open-source LLM, is a big deal, but not because there's anything new or special about it, but rather specifically because it's legally airtight. Unlike the models that were fine-tuned based on the leaked LLaMA model (many of which Meta takes down), it's based on the EleutherAI pythia model family. The training data is CC licensed and was crowd-sourced from 5000 Databricks employees.

Since it's on Hugging Face Hub, you can use it with Langchain, and I expect that it will become the Stable Diffusion of LLMs. I think especially companies that legally can't send their data off to the US will flock to using Dolly.

I kind of like how there's still this theme of woolly hooved animals (in this case a sheep), but still a divergence from the LLaMA strain of models (llama, alpaca, vicuna). I don't like how it sounds too similar to "DALL-E 2" when spoken though.

I need to make a new update post on all the AI stuff. Things move so fast that I often just can't be bothered! I'm making this post mostly for myself and people who ask about something very specific.

LangChain recently announced classes for creating custom agents (I think they had some standard Agents before that too though). Haystack has Agents too, although it seems that their definition explicitly involves looping until the output is deemed ok, as most implementations need to do this anyway.

The way I understand this and see it implemented is that it's essentially an abstraction that allows LLMs (or rather, a pipeline of LLM functions) to use "tools". A tool could for example be a calculator, a search engine, a webpage retriever, etc. The Agent has a prompt where it can reason about which tool it's supposed to use, actually use these, and make observations, which it can then output.

It also allows for the decomposition of a task and taking it step by step, which can make the system much more powerful. It's a lot closer to how a human might reason. An example of this general idea taken to the extreme is Auto-GPT which you can send on its merry way to achieve some high level goal for you and hope it doesn't cost you an arm and a leg. Anyone remember HustleGPT btw?

There's something called the ReAct framework (Reasoning + Acting -- I know, unfortunate name) which is the common "prompt engineering" part of this, and prompts using this framework are usually built in to these higher-level libraries like LangChain and Haystack. You might also see the acronym MRKL (Modular Reasoning, Knowledge and Language, pronounced "miracle") being used. This comes from this older paper (lol, last year is now "old"), and it seems that ReAct is basically a type of MRKL system that is also able to "reason". They might be used interchangeably though and people are often confused about where they differ. The ReAct paper has much clearer examples.

A common tool is now, of course, embeddings search, which you can then chain to completion / chat. You might remember two months ago when I said at the bottom of my post about GPT use cases that this is where I think the gold dust lies. Back then, I had linked gpt_index; it's now called llama_index and has become relatively popular. It lets you pick what models you want to use (including the OpenAI ones still, unlike what the rename might suggest), what vector store you want to use (including none at all if you don't have loads of data), and has a lot of useful functionality, like automatically chopping up PDFs for your embeddings.

Not too long ago, OpenAI released their own plugin for this, that has a lot of the same conveniences. One surprising thing: OpenAI's plugin supports milvus.io as a vector store (an open-source, self-hosted version of the managed pinecone.io) while llama_index doesn't. I don't think it's worth messing around with that though tbh, and I think pinecone has one of those one-click installers on the AWS marketplace. If you're using Supabase, they support the pgvector extension for PostgreSQL, so you can just store your embeddings there, but from what I hear, it's not as good.

Of course, if you're subject to EU data regulations, you're going to use llama_index rather than send your internal docs off to the US. I say internal docs, because it seems everyone and their mother is trying to enter the organisational knowledge retrieval/assistant SaaS space with this. Some even raising huge rounds, with no defensibility (not even first-mover advantage). It's legitimately blowing my mind, and hopefully we don't see a huge pendulum swing in AI as we did crypto. We probably will tbh.

The only defensibility that may make sense is if you have a data advantage. Data is the gold right now. A friend's company has financial data that is very difficult to get a hold of, and using llama_index, which is the perfect use. Another potential example: the UK government's business support hotline service is sitting on a treasure trove of chat data right now also. Wouldn't it be cool to have an actually really good AI business advisor at your beck and call? Turn that into an Agent tool, and that's more juice to just let it run the business for you outright. Accelerando autonomous corporation vibes, but I digress!

Personally, I would quite like an Obsidian plugin to help me draw connections between notes in my personal knowledge base, help me organise things, and generally allow me to have a conversation with my "memory". It's a matter of time!

I can't imagine I'm the first to try this, but new hobby acquired:

1. Go to the British Museum (other museums with statues will work too!)
2. Find broken statues
3. Take a photo
4. Erase the gaps (DALL-E 2 lets you upload and edit on the fly)
5. Write the name of the piece as the prompt, with the date
6. Use image inpainting to fill in the rest of the statue

I ran the ones below on the spot and it was quite fun. Before this, whenever I visited the British Museum (a few times a year), I didn't really give most of those statues a second glance.

An exercise for the reader (this one's interesting because they put a reference of what it could have look like if it were complete based on a different statue):

And another bust of good old Caesar (might be interesting as there's so much reference material, and it's so broken):

Try it and have fun! I'll try another batch the next time I go.

I'm glad this wasn't me with deen.ai!

For a long time I've been interested in the idea of creating a digital twin of yourself. I've tried this in the past with prompt completion trained on many years of my chat data, but it was always just a bit too inaccurate and hollow.

I also take a lot of notes, and have been taking more and more recently (a subset of these are public, like this post you're reading right now). I mentioned recently that I really think that prompt completion on top of embeddings is going to be a game-changer here.

You probably already know about prompt completion (you give it some text and it continues it like auto-complete on steroids) which underpins GPT-3, ChatGPT, etc. However, it turns out that a lot of people aren't familiar with embeddings. In a nutshell, you can turn blocks of text into high-dimensional vectors. You can then do interesting things in this vector space, for example find the distance between two vectors to reason about their similarity. CohereAI wrote an ELI5 thread about embeddings if you want to learn more.

None of this is particularly new -- you might remember StyleGAN some years ago which is what first really made this concept of a latent space really click for me, because it's so visual. You could generate a random vector that can get decoded to a random face or other random things, and you could "morph" between faces in this space by moving in this high-dimensional space. You could also find "directions" in this space (think PCA), to e.g. make a slider that increases your age when you move in that direction, while keeping other features relatively unchanging, or you could find the "femininity" direction and make someone masculine look more feminine, or a "smiling amount" direction, etc.

The equivalent of embedding text into a latent space is like when you have an image and you want to hill-climb to find a vector that generates the closest possible image to that (that you can then manipulate). I experimented with this using my profile picture (this was in August 2021, things have gotten much better since!):

Today, I discovered two new projects in this space. The first was specifically for using embeddings for search which is not that interesting but, to be fair, is what it's for. In the comments of that project on HackerNews, the second project was posted by its creator which goes a step further and puts a chat interface on top of the search, which is the exact approach I talked about before and think has a lot of potential!

Soon, I would like to be able to have a conversation with myself to organise my thoughts and maybe even engage in some self-therapy. If the conversational part of the pipeline was also fine-tuned on personal data, this could be the true starting point to creating digital twins that replace us and even outlive us!

Some weeks ago I built the "Muslim ChatGPT". From user feedback, I very quickly realised that this is one use case that absolutely won't work with generative AI. Thinking about it some more, I came to a soft conclusion that at the moment there are a set of use cases that are overall not well suited.

Verifiability

There's a class of computational problems with NP complexity. What this means is not important except that these are hard to solve but easy to verify. For example, it's hard to solve a Sudoku puzzle, but easy to check that it's correct.

Similarly, I think that there's a space of GPT use cases where the results can be verified with variable difficulty, and where having correct results is of variable importance. Here's an attempt to illustrate what some of these could be:

The top right here (high difficulty to verify, but important that the results are correct) is a "danger zone", and also where deen.ai lives. I think that as large language models become more reliable, the risks will be mitigated somewhat, but in general not enough, as they can still be confidently wrong.

In the bottom, the use cases are much less risky, because you can easily check them, but the product might still be pretty useless if the answers are consistently wrong. For example, we know that ChatGPT still tends to be pretty bad at maths and things that require multiple steps of thought, but crucially: we can tell.

The top left is kind of a weird area. I can't really think of use cases where the results are difficult to verify, but also you don't really care if they're super correct or not. The closest use case I could think of was just doing some exploratory research about a field you know nothing about, to make different parts of it more concrete, such that you can then go and google the right words to find out more from sources with high verifiability.

I think most viable use cases today live in the bottom and towards the left, but the most exciting use cases live in the top right.

Recall vs synthesis

Another important spectrum is when your use case relies on more on recall versus synthesis. Asking for the capital of France is recall, while generating a poem is synthesis. Generating a poem using the names of all cities in France is somewhere in between.

At the moment, LLMs are clearly better at synthesis than recall, and it makes sense when you consider how they work. Indeed, most of the downfalls come from when they're a bit too loose with making stuff up.

Personally, I think that recall use cases are very under-explored at the moment, and have a lot of potential. This contrast is painted quite well when comparing two recent posts on HN. The first is about someone who trained nanoGPT on their personal journal here and the output was not great. Similarly, Projects/amarbot used GPT-J fine-tuning and the results were also hit and miss.

The second uses GPT-3 Embeddings for searching a knowledge base, combined with completion to have a conversational interface with it here. This is brilliant! It solves the issues around needing the results to be as correct as possible, while still assisting you with them (e.g. if you wanted to ask for the nearest restaurants, they better actually exist)!

Somebody in the comments linked gpt_index so you can do this yourself, and I really think that this kind of architecture is the real magic dust that will revolutionise both search and discovery, and give search engines a run for their money.

Recently, people whose work I admire made me have to confront the "art not artist" dilemma once more. In this case, Nick Bostrom with racism, and Justin Roiland with domestic abuse.

Thinking about it, more generally, I guess it comes down to:

1. I can no longer consume a creator's work work without it being tainted by the context of their negative actions, so it became worse for me
2. I do not want to a give a voice/reach to their views by making them more famous
3. I do not want to do 2 indirectly by financially supporting them
4. More selfishly, I do not want to be associated with them or for people to think I support their views/actions by supporting their work
5. I do not wanting to signal to others that they can normalise these kinds of views, or behave a certain way, without consequences

However, it makes me think about the question: what if an AI were to be in a similar situation? Done something good and also done something bad. The current vibe seems to be that AI is a "tool" and "guns don't kill people, people kill people". But once you assign agency to AI, it starts opening up unexplored questions I think.

For example, what if you clone an AI state, one goes on to kill, the other goes on to save lives, in what way is the other liable? It's a bit like the entanglement experiment that won the 2022 Nobel physics prize -- you're entangling across space (two forks of a mind) vs time (old "good" version of a celebrity vs new "bad" version of a celebrity) where all versions are equally capable of bad in theory. To what extent are versions of people connected, and their potential?

It also reminds me of the sci-fi story Accelerando by Charles Stross (which I recommend, and you can read online for free here) where different forks of humans can be liable for debts incurred by their forks.

On a related note, I was recently reading a section in Existential Physics by Sabine Hossenfelder titled "Free Will and Morals". Forgive the awful photos, but give it a read:

So it doesn't even have to be AI. If someone is criminally insane, they are no longer agents responsible for their own actions, but rather chaotic systems to be managed, just like you don't "blame" the weather for being bad, or a small child for making mistakes.

Then, what if in a sufficiently advanced society we could simply alter our memories or reprogram criminal intent away? Are we killing the undesirable version? The main reasons for punishment are retribution, incapacitation, deterrence, and rehabilitation, but is there research out there that has really thought about how this applies to AI?

There's a fifth reason that applies only to AI: Roko's Basilisk (warning: infohazard) but it's all connected, as I wonder what majority beliefs we hold today that future cultures will find morally reprehensible. It might be things like consuming animals or the treatment of non-human intelligence that is equivalent to or greater than humans by some metric. At least we can say that racism and domestic violence are pretty obviously bad though.

Great article on some ways to interact with ChatGPT: https://oneusefulthing.substack.com/p/how-to-use-chatgpt-to-boost-your. I find it funny that so many people speak to ChatGPT politely (I do too). I wonder if post-singularity we'll be looked upon more favourably than the impolite humans.

Last weekend I built a small AI product: https://deen.ai. Over the course of the week I've been gathering feedback from friends and family (Muslim and non-Muslim). In the process I learned a bunch and made things that will be quite useful for future projects too. More info here!

Not too long ago I mentioned that the search engines will need to add ChatGPT-like functionality in order to stay relevant, that there's already a browser extension that does this for Google, and that Google has declared code red. Right on schedule, yesterday Microsoft announced that they're adding ChatGPT to Bing. (If you're not aware, Microsoft is a 10-figure investor in OpenAI, and OpenAI has granted an exclusive license to Microsoft, but let's not get into how "open" OpenAI is).

I heard about this via this HackerNews post and someone in the comments (can't find it now) was saying that this will kill original content as we know it because traffic won't go to people's websites anymore. After all, why click through to websites, all with different UIs and trackers and ads, when the chat bot can just give you the answers you're looking for as it's already scraped all that content. To be honest, if this were the case, I'm not so sure if it's such a bad thing. Let me explain!

First of all, have you seen the first page of Google these days? It's all listicles, content marketing, and SEO hacks. I was not surprised to hear that more and more people use TikTok as a search engine. I personally add "site:reddit.com" to my searches when I'm trying to compare products for example, to try and get some kind of real human opinions, but even that might not be viable soon. You just can't easily find what you need anymore these days without wading through ads and spam.

Monetising content through ads never really seemed like the correct approach to me (and I'm not just saying that as a consistent user of extensions that block ads and skip sponsored segments in YouTube videos). It reminds me a lot of The Fable of the Dragon-Tyrant. I recommend reading it as it's a useful metaphor, and here's why it reminds me (skip the rest of this paragraph if you don't want spoilers): there's a dragon that needs to be fed humans or it would kill everyone. Entire industries spring up around the efficient feeding of the dragon. When humans finally figured out how to kill it, there was huge resistance, as among other things, "[t]he dragon-administration provided many jobs that would be lost if the dragon was slaughtered".

I feel like content creators should not have to rely on ads in the first place in order to be able to create that content. I couldn't tell you what the ideal model is, but I really prefer the Patreon kind of model, which goes back to the ancient world through art patronage. While this doesn't make as much money as ads, I feel like there will come a point where creating content and expressing yourself is so much easier/cheaper/faster than it is today, that you won't have high costs to maintain it on average (just look at TikTok). From the other side, I feel like discovery will become so smooth and accurate, that all you need to do is create something genuinely in demand and it will be discovered on its own, without trying to employ growth hacks and shouting louder than others. I think this will have the effect that attention will not be such a fiery commodity. People will create art primarily for the sake of art, and not to make money. Companies will create good products, rather than try to market worthless cruft. At least that's my ideal world.

So how does ChatGPT as a search engine affect this? I would say that this should not affect any kinds of social communication. I don't just mean social media, but also a large subset of blogs and similar. I think people will continue to want to follow other people, even the Twitter influencer that posts business tips, rather than ask ChatGPT "give me the top 5 business tips". I believe this for one important reason: search and discovery are two different things. With search, there is intent: I know what I don't know, and I'm trying to find out. With discovery, there isn't: I don't know what I don't know, but I loiter in places where things I would find interesting might appear, and stumble upon them by chance.

Then there's the big question of having a "knowledge engine" skipping the sources. Let's ignore the problem of inaccurate information^[1] for now. I would say that disseminating knowledge at the moment is an unsolved problem, even through peer-reviewed, scientific journal papers and conference proceedings (this is a whole different topic that I might write about some day, but I don't think it's a controversial view that peer-review and scientific publishing is very, very broken).

I do not believe that the inability to trace the source of a certain bit of knowledge is necessarily the problem. I also don't believe that it's necessarily impossible, but lets pretend that it is. It would be very silly I think to cite ChatGPT for some fact. I would bet that you could actually get a list of references to any argument you like ("Hey ChatGPT, give me 10 journal citations that climate change is not man-made").

I think the biggest use cases of ChatGPT will be to search for narrowly defined information ("what is the ffmpeg command to scale a video to 16:9?") and discover information and vocabulary on topics that you know little about in order to get a broad overview of a certain landscape.

However, I don't see ChatGPT-powered search killing informative articles written by humans. I see AI-generated articles killing articles generated by humans. "Killing" in the sense that they will be very difficult to find. And hey, if ChatGPT could actually do serious research, making novel contributions to the state-of-the-art, while citing prior work, then why shouldn't that work be of equal or greater value to the human equivalent?

In the case of AI-generated garbage drowning out good human articles just by sheer quantity though, what's the solution? I think there are a number of things that would help:

1. Being able to trace sources and build trust metrics for specific sources. The consumer of the content of course wouldn't want to check every source, but they can trust that the reputable journalist or tech reviewer did their due diligence.
2. Collaborative curation: wikis (and Wikipedia itself) having transparent and well-enforced moderation. ChatGPT can be trained on this information, but if a concept surfaces in a chat, it can always be looked up in this structured repository of information. This will ideally be as objective as possible, so where you would have usually looked at a "Jira vs Linear" article and wonder which one of those two organisations wrote it, a lot more energy will be aimed at these "comparison of project management software" tables on Wikipedia, with a higher degree of accountability.
3. For things that aren't general knowledge (e.g. let's say you wanted to document a personal project), to have some set standards in order to contribute this information to a bigger collection of federated knowledge. No, I'm not just reinventing the internet, think more of a federated wiki that's marked up and structured in such a way that indexing/search is much less data-miney and prone to SEO tricks. A truly collaborative digital garden.

Overall I think that ChatGPT as the default means of finding information is a net positive thing and may kill business models that were flawed from the start, making way for something better.

I finally wrote an article on my thoughts about ChatGPT after a lot of repeated questions/answers from/to people: https://yousefamar.com/memo/articles/ai/chatgpt/

This is one of those things where I'm not sure it should really be an "article" but instead something more akin to a living document that I update continuously, maybe with a chronological log included. At the same time, a lot of the content is temporally bound and will probably lose relevance quite fast. Something to figure out in the future!

Amarbot was using GPT-J (fine-tuned on my chat history) in order to talk like me. It's not easy to do this if you follow the instructions in the main repo, plus you need a beefy GPU. I managed to do my training in the cloud for quite cheap using Forefront. I had a few issues (some billing-related, some privacy-related) but it seems to be a small startup, and the founder himself helped me resolve these issues on Discord. As far as I could see, this was the cheapest and easiest way out there to train GPT-J models.

Unfortunately, they're shutting down.

As of today, their APIs are still running, but the founder says they're winding down as soon as they send all customers their requested checkpoints (still waiting for mine). This means Amarbot might not have AI responses for a while soon, until I find a different way to run the model.

As for fine-tuning, there no longer seems to be an easy way to do this (unless Forefront open sources their code, which they might, but even then someone has to host it). maybe#6742 on Discord has made a colab notebook that fine-tunes GPT-J in 8-bit and kindly sent it to me.

I've always thought that serverless GPUs would be the holy grail of the whole microservices paradigm, and it might be close, but hopefully that would make fine-tuning easy and accessible again.

/u/dismantlemars created a colab to run OpenAI's new Point-E model that you can use here. My first few experiments were interesting though not very usable yet! Supposedly it's thousands of times faster than DreamFusion though (the most well known crack at this). It took me about 30 secs to generate models, and converting the point cloud to a mesh was instant.

I tried to first turn my profile picture into 3D, which came out all Cronenberg'd. To be fair, the example images are all really clean renderings of 3D models, rather than a headshot of a human.

Then I tried the text prompt "a pink unicorn" which came out as an uninteresting pink blob vaguely in the shape of a rocking horse. Simply "unicorn" looked a bit more like a little dinosaur.

And finally, "horse" looked like a goat-like horse in the end.

The repo does say that the text to point cloud model, compared to the image to point cloud model is "small, worse quality [...]. This model's capabilities are limited, but it does understand some simple categories and colors."

I still find it very exciting that this is even possible in the first place. Probably less than a year ago, I spoke to the anything.world team, and truly AI-generated models seemed so far out of reach. Now I feel like it won't be much longer before we can populate entire virtual worlds just by speaking!

On a related note, I recommend that you join the Luma waitlist for an API over DreamFusion.

There are APIs out there for translating natural language to actions that a machine can take. An example from wit.ai is the IoT thermostat use case.

But why not instead use GPT-3? It ought to be quite good at this. And as I suspected, the results were quite good! The green highlighted text is AI-generated (so were the closing braces, but for some reason it didn't highlight those).

I think there's a lot here that can be expanded! E.g. you could define a schema beforehand rather than just give it some examples like I have, but I quite like this test-driven approach of defining what I actually want.

I did some tweaks to teach it that I want it to put words in my mouth as it were. It invented a new intent that I hadn't defined, so it would probably be useful to define an array of valid intents at the top. It did however manage to sweet-talk my "wife"!

I think this could work quite well in conjunction with other "modules", e.g. a prompt that takes a recipient, and a list of people I know (and what their relationship is to me), and outputs a phone number for example.

Amazon's creating AI-generated animated bedtime stories (story arc, images, and accompanying music) with customisable setting, tone, characters, and score. I believe that procedurally generated virtual worlds will be one of the prime use cases for these large models, and this is one example that I expect to see more of!

I think the most difficult part here will be to craft truly compelling and engaging stories, though this is probably soon to be solved. My brother and I attempted a similar project (AI-generated children's books) and the quality overall was not good enough at the time, but at the speed these things move I expect that to be a thing of the past in a matter of months!

Seems like GPT-4 is just around the corner! I'm really looking forward to it and not just the improvement on GPT-3, but the multi-modal inputs. I really think GPT-4 and models like it will be central to our future.

Nvidia's new diffusion model is really pushing the envelope. A lot of exciting capabilities!

I'm certain the market for GPT3-based spreadsheet plugins/add-ons is ripe for sales much more than libraries that target developers like cerebrate.ai. I've seen a general-purpose add-on for Google Sheets here, but I think that crafting these prompts to do specific things and wrapping these in higher-level functions has much more potential.
