Large Language Models (LLMs) are the class of technology behind generative text AI systems like OpenAI's ChatGPT, Google's Gemini and Anthropic's Claude.

2024

Introducing Llama-3-Groq-Tool-Use Models (via) New from Groq: two custom fine-tuned Llama 3 models specifically designed for tool use. Hugging Face model links:

Groq's own internal benchmarks put their 70B model at the top of the Berkeley Function-Calling Leaderboard with a score of 90.76 (and 89.06 for their 8B model, which would put it at #3). For comparison, Claude 3.5 Sonnet scores 90.18 and GPT-4-0124 scores 88.29.

The two new Groq models are also available through their screamingly-fast (fastest in the business?) API, running at 330 tokens/s and 1050 tokens/s respectively.

Here's the documentation on how to use tools through their API.

AI Tooling for Software Engineers in 2024. Gergely Orosz reports back on the survey he ran of 211 tech professionals concerning their use of generative AI. One interesting result:

The responses reveal that as many professionals are using both ChatGPT and GitHub Copilot as all other tools combined!

I agree with Gergely's conclusion:

We’re in the midst of a significant tooling change, with AI-augmented software engineering becoming widespread across tech. Basically, these tools have too many upsides for developers to ignore them: it’s easier and faster to switch between stacks, easier to get started on projects, and simpler to become productive in unfamiliar codebases. Of course there are also downsides, but being aware of them means they can be mitigated.

Introducing Eureka Labs (via) Andrej Karpathy's new AI education company, exploring an AI-assisted teaching model:

The teacher still designs the course materials, but they are supported, leveraged and scaled with an AI Teaching Assistant who is optimized to help guide the students through them. This Teacher + AI symbiosis could run an entire curriculum of courses on a common platform.

On Twitter Andrej says:

@EurekaLabsAI is the culmination of my passion in both AI and education over ~2 decades. My interest in education took me from YouTube tutorials on Rubik's cubes to starting CS231n at Stanford, to my more recent Zero-to-Hero AI series. While my work in AI took me from academic research at Stanford to real-world products at Tesla and AGI research at OpenAI. All of my work combining the two so far has only been part-time, as side quests to my "real job", so I am quite excited to dive in and build something great, professionally and full-time.

The first course will be LLM101n - currently just a stub on GitHub, but with the goal to build an LLM chat interface "from scratch in Python, C and CUDA, and with minimal computer science prerequisites".

Codestral Mamba. New 7B parameter LLM from Mistral, released today. Codestral Mamba is "a Mamba2 language model specialised in code generation, available under an Apache 2.0 license".

This the first model from Mistral that uses the Mamba architecture, as opposed to the much more common Transformers architecture. Mistral say that Mamba can offer faster responses irrespective of input length which makes it ideal for code auto-completion, hence why they chose to specialise the model in code.

It's available to run locally with the mistral-inference GPU library, and Mistral say "For local inference, keep an eye out for support in llama.cpp" (relevant issue).

It's also available through Mistral's La Plateforme API. I just shipped llm-mistral 0.4 adding a llm -m codestral-mamba "prompt goes here" default alias for the new model.

Also released today: MathΣtral, a 7B Apache 2 licensed model "designed for math reasoning and scientific discovery", with a 32,000 context window. This one isn't available through their API yet, but the weights are available on Hugging Face.

OpenAI and Anthropic focused on building models and not worrying about products. For example, it took 6 months for OpenAI to bother to release a ChatGPT iOS app and 8 months for an Android app!

Google and Microsoft shoved AI into everything in a panicked race, without thinking about which products would actually benefit from AI and how they should be integrated.

Both groups of companies forgot the “make something people want” mantra. The generality of LLMs allowed developers to fool themselves into thinking that they were exempt from the need to find a product-market fit, as if prompting is a replacement for carefully designed products or features. [...]

But things are changing. OpenAI and Anthropic seem to be transitioning from research labs focused on a speculative future to something resembling regular product companies. If you take all the human-interest elements out of the OpenAI boardroom drama, it was fundamentally about the company's shift from creating gods to building products.

We've doubled the max output token limit for Claude 3.5 Sonnet from 4096 to 8192 in the Anthropic API.

Just add the header "anthropic-beta": "max-tokens-3-5-sonnet-2024-07-15" to your API calls.

So much of knowledge/intelligence involves translating ideas between fields (domains). Those domains are walls the keep ideas siloed. But LLMs can help break those walls down and encourage humans to do more interdisciplinary thinking, which may lead to faster discoveries.

And note that I am implying that humans will make the breakthroughs, using LLMs as translation tools when appropriate, to help make connections. LLMs are strongest as translators of information that you provide. BYOD: Bring your own data!

Imitation Intelligence, my keynote for PyCon US 2024

Visit Imitation Intelligence, my keynote for PyCon US 2024

I gave an invited keynote at PyCon US 2024 in Pittsburgh this year. My goal was to say some interesting things about AI—specifically about Large Language Models—both to help catch people up who may not have been paying close attention, but also to give people who were paying close attention some new things to think about.

The Death of the Junior Developer (via) Steve Yegge's speculative take on the impact LLM-assisted coding could have on software careers.

Steve works on Cody, an AI programming assistant, so he's hardly an unbiased source of information. Nevertheless, his collection of anecdotes here matches what I've been seeing myself.

Steve coins the term here CHOP, for Chat Oriented Programming, where the majority of code is typed by an LLM that is directed by a programmer. Steve describes it as "coding via iterative prompt refinement", and argues that the models only recently got good enough to support this style with GPT-4o, Gemini Pro and Claude 3 Opus.

I've been experimenting with this approach myself on a few small projects (see this Claude example) and it really is a surprisingly effective way to work.

Also included: a story about how GPT-4o produced a bewitchingly tempting proposal with long-term damaging effects that only a senior engineer with deep understanding of the problem space could catch!

I'm in strong agreement with this thought on the skills that are becoming most important:

Everyone will need to get a lot more serious about testing and reviewing code.

Why The Atlantic signed a deal with OpenAI. Interesting conversation between Nilay Patel and The Atlantic CEO (and former journalist/editor) Nicholas Thompson about the relationship between media organizations and LLM companies like OpenAI.

On the impact of these deals on the ongoing New York Times lawsuit:

One of the ways that we [The Atlantic] can help the industry is by making deals and setting a market. I believe that us doing a deal with OpenAI makes it easier for us to make deals with the other large language model companies if those come about, I think it makes it easier for other journalistic companies to make deals with OpenAI and others, and I think it makes it more likely that The Times wins their lawsuit.

How could it help? Because deals like this establish a market value for training content, important for the fair use component of the legal argument.

Yeah, unfortunately vision prompting has been a tough nut to crack. We've found it's very challenging to improve Claude's actual "vision" through just text prompts, but we can of course improve its reasoning and thought process once it extracts info from an image.

In general, I think vision is still in its early days, although 3.5 Sonnet is noticeably better than older models.

Anthropic cookbook: multimodal. I'm currently on the lookout for high quality sources of information about vision LLMs, including prompting tricks for getting the most out of them.

This set of Jupyter notebooks from Anthropic (published four months ago to accompany the original Claude 3 models) is the best I've found so far. Best practices for using vision with Claude includes advice on multi-shot prompting with example, plus this interesting think step-by-step style prompt for improving Claude's ability to count the dogs in an image:

You have perfect vision and pay great attention to detail which makes you an expert at counting objects in images. How many dogs are in this picture? Before providing the answer in <answer> tags, think step by step in <thinking> tags and analyze every part of the image.

Vision language models are blind (via) A new paper exploring vision LLMs, comparing GPT-4o, Gemini 1.5 Pro, Claude 3 Sonnet and Claude 3.5 Sonnet (I'm surprised they didn't include Claude 3 Opus and Haiku, which are more interesting than Claude 3 Sonnet in my opinion).

I don't like the title and framing of this paper. They describe seven tasks that vision models have trouble with - mainly geometric analysis like identifying intersecting shapes or counting things - and use those to support the following statement:

The shockingly poor performance of four state-of-the-art VLMs suggests their vision is, at best, like of a person with myopia seeing fine details as blurry, and at worst, like an intelligent person that is blind making educated guesses.

While the failures they describe are certainly interesting, I don't think they justify that conclusion.

I've felt starved for information about the strengths and weaknesses of these vision LLMs since the good ones started becoming available last November (GPT-4 Vision at OpenAI DevDay) so identifying tasks like this that they fail at is useful. But just like pointing out an LLM can't count letters doesn't mean that LLMs are useless, these limitations of vision models shouldn't be used to declare them "blind" as a sweeping statement.

Claude: You can now publish, share, and remix artifacts. Artifacts is the feature Anthropic released a few weeks ago to accompany Claude 3.5 Sonnet, allowing Claude to create interactive HTML+JavaScript tools in response to prompts.

This morning they added the ability to make those artifacts public and share links to them, which makes them even more useful!

Here's my box shadow playground from the other day, and an example page I requested demonstrating the Milligram CSS framework - Artifacts can load most code that is available via cdnjs so they're great for quickly trying out new libraries.

hangout_services/thunk.js (via) It turns out Google Chrome (via Chromium) includes a default extension which makes extra services available to code running on the *.google.com domains - tweeted about today by Luca Casonato, but the code has been there in the public repo since October 2013 as far as I can tell.

It looks like it's a way to let Google Hangouts (or presumably its modern predecessors) get additional information from the browser, including the current load on the user's CPU. Update: On Hacker News a Googler confirms that the Google Meet "troubleshooting" feature uses this to review CPU utilization.

I got GPT-4o to help me figure out how to trigger it (I tried Claude 3.5 Sonnet first but it refused, saying "Doing so could potentially violate terms of service or raise security and privacy concerns"). Paste the following into your Chrome DevTools console on any Google site to see the result:

chrome.runtime.sendMessage(
  "nkeimhogjdpnpccoofpliimaahmaaome",
  { method: "cpu.getInfo" },
  (response) => {
    console.log(JSON.stringify(response, null, 2));
  },
);

I get back a response that starts like this:

{
  "value": {
    "archName": "arm64",
    "features": [],
    "modelName": "Apple M2 Max",
    "numOfProcessors": 12,
    "processors": [
      {
        "usage": {
          "idle": 26890137,
          "kernel": 5271531,
          "total": 42525857,
          "user": 10364189
        }
      }, ...

The code doesn't do anything on non-Google domains.

Luca says this - I'm inclined to agree:

This is interesting because it is a clear violation of the idea that browser vendors should not give preference to their websites over anyone elses.

Inside the labs we have these capable models, and they're not that far ahead from what the public has access to for free. And that's a completely different trajectory for bringing technology into the world that what we've seen historically. It's a great opportunity because it brings people along. It gives them intuitive sense for the capabilities and risks and allows people to prepare for the advent of bringing advanced AI into the world.

Jevons paradox (via) I've been thinking recently about how the demand for professional software engineers might be affected by the fact that LLMs are getting so good at producing working code, when prompted in the right way.

One possibility is that the price for writing code will fall, in a way that massively increases the demand for custom solutions - resulting in a greater demand for software engineers since the increased value they can provide makes it much easier to justify the expense of hiring them in the first place.

TIL about the related idea of the Jevons paradox, currently explained by Wikipedia like so:

[...] when technological progress increases the efficiency with which a resource is used (reducing the amount necessary for any one use), but the falling cost of use induces increases in demand enough that resource use is increased, rather than reduced.

Box shadow CSS generator (via) Another example of a tiny personal tool I built using Claude 3.5 Sonnet and artifacts. In this case my prompt was:

CSS for a slight box shadow, build me a tool that helps me twiddle settings and preview them and copy and paste out the CSS

I changed my mind half way through typing the prompt and asked it for a custom tool, and it built me this!

Box shadow CSS generator. Shows a preview, then provides sliders to set Horizontal Offset, Vertical Offset, Blur Radius,  Spread Radius,  Color and Opacity - plus the generated CSS and a Copy to Clipboard button

Here's the full transcript - in a follow-up prompt I asked for help deploying it and it rewrote the tool to use <script type="text/babel"> and the babel-standalone library to add React JSX support directly in the browser - a bit of a hefty dependency (387KB compressed / 2.79MB total) but I think acceptable for this kind of one-off tool.

Being able to knock out tiny custom tools like this on a whim is a really interesting new capability. It's also a lot of fun!

Home-Cooked Software and Barefoot Developers. I really enjoyed this talk by Maggie Appleton from this year's Local-first Conference in Berlin.

For the last ~year I've been keeping a close eye on how language models capabilities meaningfully change the speed, ease, and accessibility of software development. The slightly bold theory I put forward in this talk is that we're on a verge of a golden age of local, home-cooked software and a new kind of developer – what I've called the barefoot developer.

It's a great talk, and the design of the slides is outstanding.

It reminded me of Robin Sloan's An app can be a home-cooked meal, which Maggie references in the talk. Also relevant: this delightful recent Hacker News thread, Ask HN: Is there any software you only made for your own use but nobody else?

My favourite version of our weird new LLM future is one where the pool of people who can use computers to automate things in their life is massively expanded.

The other videos from the conference are worth checking out too.

The expansion of the jagged frontier of AI capability is subtle and requires a lot of experience with various models to understand what they can, and can’t, do. That is why I suggest that people and organizations keep an “impossibility list” - things that their experiments have shown that AI can definitely not do today but which it can almost do. For example, no AI can create a satisfying puzzle or mystery for you to solve, but they are getting closer. When AI models are updated, test them on your impossibility list to see if they can now do these impossible tasks.

Chrome Prompt Playground. Google Chrome Canary is currently shipping an experimental on-device LLM, in the form of Gemini Nano. You can access it via the new window.ai API, after first enabling the "Prompt API for Gemini Nano" experiment in chrome://flags (and then waiting an indeterminate amount of time for the ~1.7GB model file to download - I eventually spotted it in ~/Library/Application Support/Google/Chrome Canary/OptGuideOnDeviceModel).

I got Claude 3.5 Sonnet to build me this playground interface for experimenting with the model. You can execute prompts, stream the responses and all previous prompts and responses are stored in localStorage.

Animated GIF demo. The prompt is Show two greetings each in French and Spanish - on clicking the button the result streams in:  French Bonjour! Bienvenue!, Spanish Hola!, Bienvenido! Scrolling down reveals the stored history, and clicking delete on that prompt removes it from the page.

Here's the full Sonnet transcript, and the final source code for the app.

The best documentation I've found for the new API is is explainers-by-googlers/prompt-api on GitHub.

gemma-2-27b-it-llamafile (via) Justine Tunney shipped llamafile packages of Google's new openly licensed (though definitely not open source) Gemma 2 27b model this morning.

I downloaded the gemma-2-27b-it.Q5_1.llamafile version (20.5GB) to my Mac, ran chmod 755 gemma-2-27b-it.Q5_1.llamafile and then ./gemma-2-27b-it.Q5_1.llamafile and now I'm trying it out through the llama.cpp default web UI in my browser. It works great.

It's a very capable model - currently sitting at position 12 on the LMSYS Arena making it the highest ranked open weights model - one position ahead of Llama-3-70b-Instruct and within striking distance of the GPT-4 class models.

Compare PDFs. Inspired by this thread on Hacker News about the C++ diff-pdf tool I decided to see what it would take to produce a web-based PDF diff visualization tool using Claude 3.5 Sonnet.

It took two prompts:

Build a tool where I can drag and drop on two PDF files and it uses PDF.js to turn each of their pages into canvas elements and then displays those pages side by side with a third image that highlights any differences between them, if any differences exist

That give me a React app that didn't quite work, so I followed-up with this:

rewrite that code to not use React at all

Which gave me a working tool! You can see the full Claude transcript in this Gist. Here's a screenshot of the tool in action:

Screenshot showing a page from a PDF, then that page with a red squiggle on it, then just the squiggle

Being able to knock out little custom interactive web tools like this in a couple of minutes is so much fun.

Absolutely any time I try to explore something even slightly against commonly accepted beliefs, LLMs always just rehash the commonly accepted beliefs.

As a researcher, I find this behaviour worse than unhelpful. It gives the mistaken impression that there's nothing to explore.

We argued that ChatGPT is not designed to produce true utterances; rather, it is designed to produce text which is indistinguishable from the text produced by humans. It is aimed at being convincing rather than accurate. The basic architecture of these models reveals this: they are designed to come up with a likely continuation of a string of text. It’s reasonable to assume that one way of being a likely continuation of a text is by being true; if humans are roughly more accurate than chance, true sentences will be more likely than false ones. This might make the chatbot more accurate than chance, but it does not give the chatbot any intention to convey truths. This is similar to standard cases of human bullshitters, who don’t care whether their utterances are true; good bullshit often contains some degree of truth, that’s part of what makes it convincing.

I gave the opening keynote at the AI Engineer World’s Fair yesterday. I was a late addition to the schedule: OpenAI pulled out of their slot at the last minute, and I was invited to put together a 20 minute talk with just under 24 hours notice!

picopilot (via) Kyle Carberry's "GitHub Copilot in 70 lines of JavaScript". The title is a little hyperbolic, but the code itself really does implement an OpenAI powered Visual Studio Code text completion extension in 71 lines of code. This is an excellent example for learning what a minimal VS Code extension looks like.

Here's the system prompt it uses:

You provide code completion results given a prefix and suffix. Respond with a JSON object with the key 'completion' containing a suggestion to place between the prefix and suffix. Follow existing code styles. Listen to comments at the end of the prefix. The language is "{language}".

Then it passes the prefix and suffix as two user messages, and uses the "response_format": {"type": "json_object"} option to enforce JSON output from the GPT-4o API.

The feature this is missing is the thing that makes GitHub Copilot so impressive: Copilot does a whole bunch of clever tricks to find snippets of relevant code from the current and other nearby files and includes them with the prompt, resulting in much higher quality completions.

Claude Projects. New Claude feature, quietly launched this morning for Claude Pro users. Looks like their version of OpenAI's GPTs, designed to take advantage of Claude's 200,000 token context limit:

You can upload relevant documents, text, code, or other files to a project’s knowledge base, which Claude will use to better understand the context and background for your individual chats within that project. Each project includes a 200K context window, the equivalent of a 500-page book, so users can add all of the insights needed to enhance Claude’s effectiveness.

You can also set custom instructions, which presumably get added to the system prompt.

I tried dropping in all of Datasette's existing documentation - 693KB of .rst files (which I had to rename to .rst.txt for it to let me upload them) - and it worked and showed "63% of knowledge size used".

This is a slightly different approach from OpenAI, where the GPT knowledge feature supports attaching up to 20 files each with up to 2 million tokens, which get ingested into a vector database (likely Qdrant) and used for RAG.

It looks like Claude instead handle a smaller amount of extra knowledge but paste the whole thing into the context window, which avoids some of the weirdness around semantic search chunking but greatly limits the size of the data.

My big frustration with the knowledge feature in GPTs remains the lack of documentation on what it's actually doing under the hood. Without that it's difficult to make informed decisions about how to use it - with Claude Projects I can at least develop a robust understanding of what the tool is doing for me and how best to put it to work.

No equivalent (yet) for the GPT actions feature where you can grant GPTs the ability to make API calls out to external systems.

llama.ttf (via) llama.ttf is "a font file which is also a large language model and an inference engine for that model".

You can see it kick into action at 8m28s in this video, where creator Søren Fuglede Jørgensen types "Once upon a time" followed by dozens of exclamation marks, and those exclamation marks then switch out to render a continuation of the story. But... when they paste the code out of the editor again it shows as the original exclamation marks were preserved - the LLM output was presented only in the way they were rendered.

The key trick here is that the font renderer library HarfBuzz (used by Firefox, Chrome, Android, GNOME and more) added a new WebAssembly extension in version 8.0 last year, which is powerful enough to run a full LLM based on the tinyllama-15M model - which fits in a 60MB font file.

(Here's a related demo from Valdemar Erk showing Tetris running in a WASM font, at 22m56s in this video.)

The source code for llama.ttf is available on GitHub.
