Earlier quoted context omitted.

I do it because 1) I am fascinated that I can and 2) at some point the online models will be enshitified — and I can then permanently fall back on my last good local version.

love the first and am sad you’re going to be right about the second

When it was floated about that the DeepSeek model was to be banned in the U.S., I grabbed it as fast as I could.

Funny how that works.

Model cards, for the people interested in the guts: https://cdn.openai.com/pdf/419b6906-9da6-406c-a19d-1bb078ac7... In my mind, I’m comparing the model architecture they describe to what the leading open-weights models (Deepseek, Qwen, GLM, Kimi) have been doing. Honestly, it just seems “ok” at a technical level: - both models use standard Grouped-Query Attention (64 query heads, 8 KV heads). The card talks about how…

I don't know how to ask this without being direct and dumb: Where do I get a layman's introduction to LLMs that could work me up to understanding every term and concept you just discussed? Either specific videos, or if nothing else, a reliable Youtube channel?

Try Andrej Karpathy's YouTube videos. I also really liked the Dive into Deep Learning book at d2l.ai

Sorry to ask what is possibly a dumb question, but is this effectively the whole kit and kaboodle, for free, downloadable without any guardrails? I often thought that a worrying vector was how well LLMs could answer downright terrifying questions very effectively. However the guardrails existed with the big online services to prevent those questions being asked. I guess they were always unleashed with other open sour…

These models still have guardrails. Even locally they won't tell you how to make bombs or write pornographic short stories.

are the guardrails trained in? I had presumed they might be a thin, removable layer at the top. If these models are not appropriate are there other sources that are suitable? Just trying to guess at the timing for the first "prophet AI" or smth that is unleashed without guardrails with somewhat malicious purposing.

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…

How up to date are you on current open weights models? After playing around with it for a few hours I find it to be nowhere near as good as Qwen3-30B-A3B. The world knowledge is severely lacking in particular.

Why does it need knowledge when it can just call tools to get it?

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…

I’m also very interested to know how well these models handle tool calling as I haven’t been able to make it work after playing with them for a few hours. Looks promising tho.

update: I’ve tried to use lm-studio (like the author) and the tool request kept failing due to a mismatch in the prompt template. I guess they’ll fix it but seems sloppy from lm-studio not having tested this before release.

I tried 20b locally and it couldn't reason a way out of a basic river crossing puzzle with labels changed. That is not anywhere near SOTA. In fact it's worse than many local models that can do it, including e.g. QwQ-32b.

Seeing a 20B model competing with o3's performance is mind blowing like just a year ago, most of us would've called this impossible - not just the intelligence leap, but getting this level of capability in such a compact size. I think that the point that makes me more excited is that we can train trillion-parameter giants and distill them down to just billions without losing the magic. Imagine coding with Claude 4 Op…

It's not even a 20b model. It's 20b MoE with 3.6b active params.

But it does not actually compete with o3 performance. Not even close. As usual, the metrics are bullshit. You don't know how good the model actually is until you grill it yourself.

Orthogonal, but I just wanted to say how awesome Ollama is. It took 2 seconds to find the model and a minute to download and now I'm using it. Kudos to that team.

It's just as easy with LM Studio.

All the real heavy lifting is done by llama.cpp, and for the distribution, by HuggingFace.

Text only, when local multimodal became table stakes last year.

The community can always figure out hooking it up to other modalities. Native might be better, but no native multimodal model is very competitive yet, so better to take a competitive model and latch on vision/audio

> so better to take a competitive model and latch on vision/audio

Can this be done by a third party or would it have to be OpenAI?

It's the first model I've used that refused to answer some non-technical questions about itself because it "violates the safety policy" (what?!). Haven't tried it in coding or translation or anything otherwise useful yet, but the first impression is that it might be way too filtered, as it sometimes refuses or has complete meltdowns and outputs absolute garbage when just trying to casually chat with it. Pretty weird.

Update: it seems to be completely useless for translation. It either refuses, outputs garbage, or changes the meaning completely for completely innocuous content. This already is a massive red flag.
