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.
> 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…

Are there any 24GB cards/3090s which fit in ~300mm without an angle grinder?
https://skinflint.co.uk/?cat=gra16_512&hloc=uk&v=e&hloc=at&h... 5070 Ti Super will also have 24GB.
Admittedly a little tempting to see how the 5070 Ti Super shakes out!

+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.
Possibly stupid question, but does this apply to things like M365 too? Because just like with Inference providers, the only thing keeping them from reading/abusing your data is a pinky promise contract. Basically, isn't your data as safe/unsafe in a sharepoint folder as it is sending it to a paid inference provider?
Re: Open models by OpenAI
#694Just 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 have a bunch of scripts that use tool calling. Qwen-3-32B handles everything flawlessly at 60 tok/sec. Gpt-oss-120B breaks in some cases and runs at mere 35 tok/sec (doesn't fit on the GPU).
But I hope there's still some ironing out to do in llama.cpp and in the quants. So far it feels lackluster compared to Qwen3-32B and GLM-4.5-Air

I tried the two US presidents having the same parents one, and while it understood the intent, it got caught up in being adamant that Joe Biden won the election in 2024 and anything I do to try and tell it otherwise is dismissed as being false and expresses quite definitely that I need to do proper research with legitimate sources.
I mean I would hardly blame the specific model, Anthropic has a specific mention in their system prompts on trump winning. For some reason llms get confused with this one.

Generation is usually fast, but prompt processing is the main limitation with local agents. I also have a 128 GB M4 Max. How is the prompt processing on long prompts? processing the system prompt for Goose always takes quite a while for me. I haven't been able to download the 120B yet, but I'm looking to switch to either that or the GLM-4.5-Air for my main driver.
You mentioned "on local agents". I've noticed this too. How do ChatGPT and the others get around this, and provide instant responses on long conversations?

Agree. Concrete example: "What was the Japanese codeword for Midway Island in WWII?" Answer on Wikipedia: https://en.wikipedia.org/wiki/Battle_of_Midway#U.S._code-bre... dolphin3.0-llama3.1-8b Q4_K_S [4.69 GB on disk]: correct in deepseek-r1-0528-qwen3-8b Q6_K [6.73 GB]: correct in 10 seconds gpt-oss-20b MXFP4 [12.11 GB] low reasoning: wrong after 6 seconds gpt-oss-20b MXFP4 [12.11 GB] high reasoning: wrong after 3 m…
Not true: During World War II the Imperial Japanese Navy referred to Midway Island in their communications as “Milano” (ミラノ). This was the official code word used when planning and executing operations against the island, including the Battle of Midway. 12.82 tok/sec 140 tokens 7.91s to first token openai/gpt-oss-20b

It's the political bias in the training material. No surprise there.
Re: Open models by OpenAI
#699The 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…

Other models have generally failed that without a system prompt that encourages rigorous thinking. Each of the reasoning settings may very well have thinking guidance baked in there that do something similar, though.
I'm not sure it says that much that it can solve this, since it's public and can be in training data. It does say something if it can't solve it, though. So, for what it's worth, it solves it reliably for me.
Think this is the smallest model I've seen solve it.

Part of the secret sauce since O1 has been accesss the real reasoning traces, not the summaries. If you even glance at the model card you'll see this was trained on the same CoT RL pipeline as O3, and it shows in using the model: this is the most coherent and structured CoT of any open model so far. Having full access to a model trained on that pipeline is valuable to anyone doing post-training, even if it's just to…
Its CoT is sadly closer to that sanitised o3 summaries than to R1 style traces.
