The lede is being missed imo. gpt-oss:20b is a top ten model (on MMLU (right behind Gemini-2.5-Pro) and I just ran it locally on my Macbook Air M3 from last year. I've been experimenting with a lot of local models, both on my laptop and on my phone (Pixel 9 Pro), and I figured we'd be here in a year or two. But no, we're here today. A basically frontier model, running for the cost of electricity (free with a rounding…

I’m still trying to understand what is the biggest group of people that uses local AI (or will)? Students who don’t want to pay but somehow have the hardware? Devs who are price conscious and want free agentic coding? Local, in my experience, can’t even pull data from an image without hallucinating (Qwen 2.5 VI in that example). Hopefully local/small models keep getting better and devices get better at running bigger…

Don't know about the biggest, but IMO the exciting things about open models is the possibility of creating whole new things.

For example, "generate a heatmap of each token/word and how 'unexpected' they are" or "find me a prompt that creates the closest match to this text"

To be efficient both require access that is not exposed over API.

I don’t get it. Wouldn’t it be Lulu in both cases?

It’s Bob or Jane. The dad of has 5 daughters. Four are listed off. So the answer for the fifth is .

Except having five daughters doesn't prevent them also having 20 sons one of whom is called Bob.

Just posted my initial impressions, took a couple of hours to write them up because there's a lot in this release! https://simonwillison.net/2025/Aug/5/gpt-oss/ TLDR: I think OpenAI may have taken the medal for best available open weight model back from the Chinese AI labs. Will be interesting to see if independent benchmarks resolve in that direction as well. The 20B model runs on my Mac laptop using less than 15GB…

Nice write up! One test I do is to give a common riddle but word it slightly to see if it can actually reason. For example: "Bobs dad has five daughters, Lala, Lele, Lili, Lolo and ???" The 20B model kept picking the answer of the original riddle, even after explaining extra information to it. The original riddle is: "Janes dad has five daughters, Lala, Lele, Lili, Lolo and ???"

Your riddle assumes the dad doesn't have any sons.

People like myself that firmly believe there will come a time, possibly very soon that all these companies (OpenAI, Anthropic etc) will raise their prices substantially. By then no one will be able to do their work to the standard expected of them without AI, and by then maybe they charge $1k per month, maybe they charge $10k. If there is no viable alternative the sky is the limit. Why do you think they continue to r…

> no high quantisation library supports two GPUs for example, and there seems to be no interest in implementating it by the guys behind the best inference tools

I'm curious to hear what you're trying to run, because I haven't used any software that is not compatible with multiple GPUs.

> In fact it's worse than many local models that can do it, including e.g. QwQ-32b. I'm not going to be surprised that a 20B 4/32 MoE model (3.6B parameters activated) is less capable at a particular problem category than a 32B dense model, and its quite possible for both to be SOTA, as state of the art at different scale (both parameter count and speed which scales with active resource needs) is going to have differ…

You’re in a bubble. It was no surprise to folks who touch grass on the regular.

> You’re in a bubble. Sure, all I have to go on from the other side of the Atlantic is the internet. So in that regard, kinda like the AI. One of the big surprises from the POV of me in Jan 2024, is that I would have anticipated Trump being in prison and not even available as an option for the Republican party to select as a candidate for office, and that even if he had not gone to jail that the Republicans would not…

I'm pretty sure you are completely correct on the last part. Nobody in Republican management wanted a second Trump term. If the candidate wasn't Trump, Republicans would have had a guaranteed victory. Imagine that infamous debate, but with some 50-year-old youngster facing Joe Biden.

It's the White House that wanted Trump to be candidate. They played Republican primary voters like a fiddle by launching a barrage of transparently political prosecutions just as Republican primaries were starting.

And then they still lost the general election.

I’ve been leaning more toward open-source LLMs lately. They’re not as hyper-optimized for performance, which actually makes them feel more like the old-school OpenAI chats-you could just talk to them. Now it’s like you barely finish typing and the model already force-feeds you an answer. Feels like these newer models are over-tuned and kind of lost that conversational flow.

Privacy, both personal and for corporate data protection is a major reason. Unlimited usage, allowing offline use, supporting open source, not worrying about a good model being taken down/discontinued or changed, and the freedom to use uncensored models or model fine tunes are other benefits (though this OpenAI model is super-censored - “safe”). I don’t have much experience with local vision models, but for text ques…

+1 - I work in finance, and there's no way we're sending our data and code outside the organization. We have our own H100s.

Do you have your own platform to run inference?

My main goal with that benchmark is to see if it can produce HTML and JavaScript code that runs without errors for a moderately complex challenge. It's not a comprehensive benchmark - there are many ways you could run it in ways that would be much more informative and robust. It's great as a quick single sentence prompt to get a feeling for if the model can produce working JavaScript or not.

Not really the other commenters are correct I feel and this is not really proving anything about the fundamental capability of the model. It’s just a hello world benchmark adding no real value, just driving blog traffic for you.

The space invaders benchmark proves that the model can implement a working HTML and JavaScript game from a single prompt. That's a pretty fundamental capability for a model.

Comparing them between models is also kind of interesting, even if it's not a flawlessly robust comparison: https://simonwillison.net/tags/space-invaders/
