  OpenAI is finally stepping into the future—open models.  They've released gpt-oss, with models at 20B and 120B parameters.  It uses a mixture-of-experts architecture, which means it runs very fast.  And yes, it'll even run on a laptop (well, some laptops).  Sadly, only ‘thinking’…

  We're excited to make this model, the result of billions of dollars of research, available to the world to get AI into the hands of the most people possible.  We believe far more good than bad will come from it; for example, gpt-oss-120b performs about as well as o3 on challengin…

  Today we release gpt-oss-120b and gpt-oss-20b—two open-weight LLMs that deliver strong performance and agentic tool use. Before release, we ran a first of its kind safety analysis where we fine-tuned the models to intentionally maximize their bio and cyber capabilities 🧵 [image]

  We released two open-weight reasoning models—gpt-oss-120b and gpt-oss-20b—under an Apache 2.0 license. Developed with open-source community feedback, these models deliver meaningful advancements in both reasoning capabilities & safety. https://openai.com/...

• @sjgadler Steven Adler on x

  Credit where it's due: OpenAl did a lot right for their OSS safety evals - they actually did some fine-tuning - they got useful external feedback - they shared which recs they adopted and which they didn't I don't always follow OAI's rationale, but it's great they share info

  gpt-oss-120b is now the leading 🇺🇸 US open weights model. Qwen3 235B from Alibaba is the leading 🇨🇳 Chinese model and offers greater intelligence, but is much larger in size (235B total parameters, 22B active, vs gpt-oss-120B's 117B total, 5B active) Link below to further [image]

  A year ago, policymakers in DC were debating a ban on open weight models. From day one, the Trump administration changed course and made clear America needs to offer the best open models for innovators to build on and for America to export. Today, our companies are leading.

• @simonw Simon Willison on x

  According to the model card gpt-oss-120b took 2.1 million H100-hours and the 20b model 1/10th of that I found quotes for H100 pricing ranging from $2/hour to $11/hour, which would indicate that the 120b model cost between $4.2m and $23.1m and the 20b between $420,000 and $2.3m

• @teortaxestex @teortaxestex on x

  Yeah, they mogged. First thing I see here, besides insane scores to params ratio (20B is MoE too! 4.25 bpw!), is that they have open sourced their reasoning effort scaling that totally destroys every other attempt. Second thing is that this 120B is trained on *a lot* of tokens. […

  The gpt-oss 120b model cost ~$4m to train, gpt-oss 20b cost ~$400k That's on H100s (assume $2/hour), next year will be way cheaper & faster on blackwell/VR etc It's really all about the data, not the megacompute

  The OpenAI open weights models are very impressive. These basically beat every model from eight months ago & the small one runs on a laptop. For example, when HLE came out in January, the top score was 3-4%. Been playing with the models and so far they feel like their scores. [im…
