A simple Python implementation of the ReAct pattern for LLMs. I implemented the ReAct pattern (for Reason+Act) described in this paper. It's a pattern where you implement additional actions that an LLM can take - searching Wikipedia or running calculations for example - and then teach it how to request that those actions are run, then feed their results back into the LLM.

The Unpredictable Abilities Emerging From Large AI Models (via) Nice write-up of the most interesting aspect of large language models: the fact that they gain emergent abilities at certain “breakthrough” size points, and no-one is entirely sure they understand why.

Fine-tune LLaMA to speak like Homer Simpson. Replicate spent 90 minutes fine-tuning LLaMA on 60,000 lines of dialog from the first 12 seasons of the Simpsons, and now it can do a good job of producing invented dialog from any of the characters from the series. This is a really interesting result: I’ve been skeptical about how much value can be had from fine-tuning large models on just a tiny amount of new data, assuming that the new data would be statistically irrelevant compared to the existing model. Clearly my mental model around this was incorrect.

OpenAI to discontinue support for the Codex API (via) OpenAI shutting off access to their Codex model—a GPT3 variant fine-tuned for code related tasks, but that was being used for all sorts of other purposes—partly because it had been in a beta phase for over a year where OpenAI didn’t charge anything for it. This feels to me like a major strategic misstep for OpenAI: they’re only giving three days notice, which is shaking people’s confidence in them as a stable platform for building on at the very moment when competition from other vendors (and open source alternatives) is heating up.

Adobe made an AI image generator — and says it didn’t steal artists’ work to do it. Adobe Firefly is a brand new text-to-image model which Adobe claim was trained entirely on fully licensed imagery—either out of copyright, specially licensed or part of the existing Adobe Stock library. I’m sure they have the license, but I still wouldn’t be surprised to hear complaints from artists who licensed their content to Adobe Stock who didn’t anticipate it being used for model training.

Bing Image Creator comes to the new Bing. Bing Chat is integrating DALL-E directly into their interface, giving it the ability to generate images when prompted to do so.

Google Bard is now live. Google Bard launched today. There’s a waiting list, but I made it through within a few hours of signing up, as did other people I’ve talked to. It’s similar to ChatGPT and Bing—it’s the same chat interface, and it can clearly run searches under the hood (though unlike Bing it doesn’t tell you what it’s looking for).

The Age of AI has begun. Bill Gates calls GPT-class large language models “the most important advance in technology since the graphical user interface”. His essay here focuses on the philanthropy angle, mostly from the point of view of AI applications in healthcare, education and concerns about keeping access to these new technologies as equitable as possible.

Datasette: Gather feedback on new ?_extra= design. I just landed the single biggest backwards-incompatible change to Datasette ever, in preparation for the 1.0 release. It’s a change to the default JSON format from the Datasette API—the new format is much slimmer, and can be expanded using a new ?_extra= query string parameter. I’m desperately keen on getting feedback on this change! This issues has more details and a call for feedback.

Teaching News Apps with Codespaces (via) Derek Willis used GitHub Codespaces for the latest data journalism class he taught, and it eliminated the painful process of trying to get students on an assortment of Mac, Windows and Chromebook laptops all to a point where they could start working and learning together.

mitsua-diffusion-one (via) “Mitsua Diffusion One is a latent text-to-image diffusion model, which is a successor of Mitsua Diffusion CC0. This model is trained from scratch using only public domain/CC0 or copyright images with permission for use.” I’ve been talking about how much I’d like to try out a “vegan” AI model trained entirely on out-of-copyright images for ages, and here one is! It looks like the training data mainly came from CC0 art gallery collections such as the Metropolitan Museum of Art Open Access.

ChatGPT plugins. ChatGPT is getting a plugins mechanism, which will allow developers to provide extra capabilities to ChatGPT, like looking up restaurants on OpenTable or fetching data from APIs. This feels like the kind of feature that could obsolete—or launch—a thousand startups. It also makes ChatGPT much more interesting as a general purpose tool, as opposed to something that only works as an interface to a language model.

ChatGPT Retrieval Plugin. “The ChatGPT Retrieval Plugin repository provides a flexible solution for semantic search and retrieval of personal or organizational documents using natural language queries.” How many existing startups were building this I wonder?

Hello Dolly: Democratizing the magic of ChatGPT with open models. A team at DataBricks applied the same fine-tuning data used by Stanford Alpaca against LLaMA to a much older model—EleutherAI’s GPT-J 6B, first released in May 2021. As with Alpaca, they found that instruction tuning took the raw model—which was extremely difficult to interact with—and turned it into something that felt a lot more like ChatGPT. It’s a shame they reused the license-encumbered 52,000 training samples from Alpaca, but I doubt it will be long before someone recreates a freely licensed alternative to that training set.

scrapeghost (via) Scraping is a really interesting application for large language model tools like GPT3. James Turk’s scrapeghost is a very neatly designed entrant into this space—it’s a Python library and CLI tool that can be pointed at any URL and given a roughly defined schema (using a neat mini schema language) which will then use GPT3 to scrape the page and try to return the results in the supplied format.

Leicester balloon riot (via) In 1864 a test flight of a new hydrogen balloon in Leicester’s Victoria Park attracted 50,000 spectators, and ended in a riot that destroyed the balloon. “Early in the afternoon there was a disturbance when a gentleman, claiming to be an aeronaut, announced that Britannia was not Coxwell’s newest and biggest balloon but an older model. This enraged the crowd who, shortly after 2pm, broke down the barrier and demanded that Coxwell take off immediately.”

I lost everything that made me love my job through Midjourney over night. A poster on r/blender describes how their job creating graphics for mobile games has switched from creating 3D models for rendering 2D art to prompting Midjourney v5 and cleaning up the results in Photoshop. “I am now able to create, rig and animate a character thats spit out from MJ in 2-3 days. Before, it took us several weeks in 3D. [...] I always was very sure I wouldn’t lose my job, because I produce slightly better quality. This advantage is gone, and so is my hope for using my own creative energy to create.”
