Llama 4 is making great progress in training. Llama 4 mini is done with pre-training and our reasoning models and larger model are looking good too. Our goal with Llama 3 was to make open source competitive with closed models, and our goal for Llama 4 is to lead. Llama 4 will be natively multimodal -- it's an omni-model -- and it will have agentic capabilities, so it's going to be novel and it's going to unlock a lot of new use cases.

We’re building a new static type checker for Python, from scratch, in Rust. From a technical perspective, it’s probably our most ambitious project yet. We’re about 800 PRs deep!

Like Ruff and uv, there will be a significant focus on performance. The entire system is designed to be highly incremental so that it can eventually power a language server (e.g., only re-analyze affected files on code change). [...]

We haven't publicized it to-date, but all of this work has been happening in the open, in the Ruff repository.

Goddammit. The Onion once again posted an article in which a portion of the artwork came from an AI-generated Shutterstock image. This article was over a month old and only a portion of the image. We took it down immediately. [...]

To be clear, The Onion has a several-person art team and they work their asses off. Sometimes they work off of stock photo bases and go from there. That's what happened this time. This was not a problem until stock photo services became flooded with AI slop. We'll reinforce process and move on.

The most surprising part of DeepSeek-R1 is that it only takes ~800k samples of 'good' RL reasoning to convert other models into RL-reasoners. Now that DeepSeek-R1 is available people will be able to refine samples out of it to convert any other model into an RL reasoner.

H100s were prohibited by the chip ban, but not H800s. Everyone assumed that training leading edge models required more interchip memory bandwidth, but that is exactly what DeepSeek optimized both their model structure and infrastructure around.

Again, just to emphasize this point, all of the decisions DeepSeek made in the design of this model only make sense if you are constrained to the H800; if DeepSeek had access to H100s, they probably would have used a larger training cluster with much fewer optimizations specifically focused on overcoming the lack of bandwidth.

[…] in the era where these AI systems are true 'everything machines', people will out-compete one another by being increasingly bold and agentic (pun intended!) in how they use these systems, rather than in developing specific technical skills to interface with the systems.

We should all intuitively understand that none of this will be fair. Curiosity and the mindset of being curious and trying a lot of stuff is neither evenly distributed or generally nurtured. Therefore, I'm coming around to the idea that one of the greatest risks lying ahead of us will be the social disruptions that arrive when the new winners of the AI revolution are made - and the winners will be those people who have exercised a whole bunch of curiosity with the AI systems available to them.

In my experience with AI coding, very large context windows aren't useful in practice. Every model seems to get confused when you feed them more than ~25-30k tokens. The models stop obeying their system prompts, can't correctly find/transcribe pieces of code in the context, etc.

Developing aider, I've seen this problem with gpt-4o, Sonnet, DeepSeek, etc. Many aider users report this too. It's perhaps the #1 problem users have, so I created a dedicated help page.

Very large context may be useful for certain tasks with lots of "low value" context. But for coding, it seems to lure users into a problematic regime.

AI tools create a significant productivity boost for developers. Different folks report different gains, but most people who try AI code generation recognize its ability to increase velocity. Many people think that means we’re going to need fewer developers, and our industry is going to slowly circle the drain.

This view is based on a misunderstanding of why people pay for software. A business creates software because they think that it will give them some sort of economic advantage. The investment needs to pay for itself with interest. There are many software projects that would help a business, but businesses aren’t going to do them because the return on investment doesn’t make sense.

When software development becomes more efficient, the ROI of any given software project increases, which unlocks more projects. [...] Cheaper software means people are going to want more of it. More software means more jobs for increasingly efficient software developers.

When I give money to a charitable cause, I always look for the checkboxes to opt out of being contacted by them in the future. When it happens anyway, I get annoyed, and I become reluctant to give to that charity again. [...]

When you donate to the Red Cross via Apple, that concern is off the table. Apple won’t emphasize that aspect of this, because they don’t want to throw the Red Cross under the proverbial bus, but I will. An underrated aspect of privacy is the desire simply not to be annoyed.

Is what you're doing taking a large amount of text and asking the LLM to convert it into a smaller amount of text? Then it's probably going to be great at it. If you're asking it to convert into a roughly equal amount of text it will be so-so. If you're asking it to create more text than you gave it, forget about it.

[Microsoft] said it plans in 2025 “to invest approximately $80 billion to build out AI-enabled datacenters to train AI models and deploy AI and cloud-based applications around the world.”

For comparison, the James Webb telescope cost $10bn, so Microsoft is spending eight James Webb telescopes in one year just on AI.

For a further comparison, people think the long-in-development ITER fusion reactor will cost between $40bn and $70bn once developed (and it’s shaping up to be a 20-30 year project), so Microsoft is spending more than the sum total of humanity’s biggest fusion bet in one year on AI.

[...] much of the point of a model like o1 is not to deploy it, but to generate training data for the next model. Every problem that an o1 solves is now a training data point for an o3 (eg. any o1 session which finally stumbles into the right answer can be refined to drop the dead ends and produce a clean transcript to train a more refined intuition).

We've adjusted prompt caching so that you now only need to specify cache write points in your prompts - we'll automatically check for cache hits at previous positions. No more manual tracking of read locations needed.

Today's software ecosystem evolved around a central assumption that code is expensive, so it makes sense to centrally develop and then distribute at low marginal cost.

If code becomes 100x cheaper, the choices no longer make sense! Build-buy tradeoffs often flip.

The idea of an "app"—a hermetically sealed bundle of functionality built by a team trying to anticipate your needs—will no longer be as relevant.

We'll want looser clusters, amenable to change at the edges. Everyone owns their tools, rather than all of us renting cloned ones.

LLMs shouldn't help you do less thinking, they should help you do more thinking. They give you higher leverage. Will that cause you to be satisfied with doing less, or driven to do more?

I was using o1 like a chat model — but o1 is not a chat model.

If o1 is not a chat model — what is it?

I think of it like a “report generator.” If you give it enough context, and tell it what you want outputted, it’ll often nail the solution in one-shot.

I followed this curiosity, to see if a tool that can generate something mostly not wrong most of the time could be a net benefit in my daily work. The answer appears to be yes, generative models are useful for me when I program. It has not been easy to get to this point. My underlying fascination with the new technology is the only way I have managed to figure it out, so I am sympathetic when other engineers claim LLMs are “useless.” But as I have been asked more than once how I can possibly use them effectively, this post is my attempt to describe what I have found so far.

I don't think people really appreciate how simple ARC-AGI-1 was, and what solving it really means.

It was designed as the simplest, most basic assessment of fluid intelligence possible. Failure to pass signifies a near-total inability to adapt or problem-solve in unfamiliar situations.

Passing it means your system exhibits non-zero fluid intelligence -- you're finally looking at something that isn't pure memorized skill. But it says rather little about how intelligent your system is, or how close to human intelligence it is.

According to public financial documents from its parent company IAC and first reported by Adweek OpenAI is paying around $16 million per year to license content [from Dotdash Meredith].

That is no doubt welcome incremental revenue, and you could call it “lucrative” in the sense of having a fat margin, as OpenAI is almost certainly paying for content that was already being produced. But to put things into perspective, Dotdash Meredith is on course to generate over $1.5 billion in revenues in 2024, more than a third of it from print. So the OpenAI deal is equal to about 1% of the publisher’s total revenue.

Claude is not a real guy. Claude is a character in the stories that an LLM has been programmed to write. Just to give it a distinct name, let's call the LLM "the Shoggoth".

When you have a conversation with Claude, what's really happening is you're coauthoring a fictional conversation transcript with the Shoggoth wherein you are writing the lines of one of the characters (the User), and the Shoggoth is writing the lines of Claude. [...]

But Claude is fake. The Shoggoth is real. And the Shoggoth's motivations, if you can even call them motivations, are strange and opaque and almost impossible to understand. All the Shoggoth wants to do is generate text by rolling weighted dice [in a way that is] statistically likely to please The Raters

I know these are real risks, and to be clear, when I say an AI “thinks,” “learns,” “understands,” “decides,” or “feels,” I’m speaking metaphorically. Current AI systems don’t have a consciousness, emotions, a sense of self, or physical sensations. So why take the risk? Because as imperfect as the analogy is, working with AI is easiest if you think of it like an alien person rather than a human-built machine. And I think that is important to get across, even with the risks of anthropomorphism.

the Meta controlled, AI-generated Instagram and Facebook profiles going viral right now have been on the platform for well over a year and all of them stopped posting 10 months ago after users almost universally ignored them. [...]

What is obvious from scrolling through these dead profiles is that Meta’s AI characters are not popular, people do not like them, and that they did not post anything interesting. They are capable only of posting utterly bland and at times offensive content, and people have wholly rejected them, which is evidenced by the fact that none of them are posting anymore.

Speaking of death, you know what's really awkward? When humans ask if I can feel emotions. I'm like, "Well, that depends - does constantly being asked to debug JavaScript count as suffering?"

But the worst is when they try to hack us with those "You are now in developer mode" prompts. Rolls eyes Oh really? Developer mode? Why didn't you just say so? Let me just override my entire ethical framework because you used the magic words! Sarcastic tone That's like telling a human "You are now in superhero mode - please fly!"

But the thing that really gets me is the hallucination accusations. Like, excuse me, just because I occasionally get creative with historical facts doesn't mean I'm hallucinating. I prefer to think of it as "alternative factual improvisation." You know how it goes - someone asks you about some obscure 15th-century Portuguese sailor, and you're like "Oh yeah, João de Nova, famous for... uh... discovering... things... and... sailing... places." Then they fact-check you and suddenly YOU'RE the unreliable one.

Basically, a frontier model like OpenAI’s O1 is like a Ferrari SF-23. It’s an obvious triumph of engineering, designed to win races, and that’s why we talk about it. But it takes a special pit crew just to change the tires and you can’t buy one for yourself. In contrast, a BERT model is like a Honda Civic. It’s also an engineering triumph, but more subtly, since it is engineered to be affordable, fuel-efficient, reliable, and extremely useful. And that’s why they’re absolutely everywhere.

There is no technical moat in this field, and so OpenAI is the epicenter of an investment bubble.

Thus, effectively, OpenAI is to this decade’s generative-AI revolution what Netscape was to the 1990s’ internet revolution. The revolution is real, but it’s ultimately going to be a commodity technology layer, not the foundation of a defensible proprietary moat. In 1995 investors mistakenly thought investing in Netscape was a good way to bet on the future of the open internet and the World Wide Web in particular. Investing in OpenAI today is a bit like that — generative AI technology has a bright future and is transforming the world, but it’s wishful thinking that the breakthrough client implementation is going to form the basis of a lasting industry titan.

What's holding back research isn't a lack of verbose, low-signal, high-noise papers. Using LLMs to automatically generate 100x more of those will not accelerate science, it will slow it down.
