This is exciting; I expect we are going to see a lot more things like this and it will be one of the most important impacts of AI. Congrats to the Future House team.https://t.co/Cxeh8UlWdk ...

GPT-5.1 is now available in the API. Pricing is the same as GPT-5.We are also releasing gpt-5.1-codex and gpt-5.1-codex-mini in the API, specialized for long-running coding tasks.Prompt caching now lasts up to 24 hours!Updated evals in our blog post. ...

Understanding neural networks through sparse circuits:OpenAI (@OpenAI):We’ve developed a new way to train small AI models with internal mechanisms that are easier for humans to understand.Language models like the ones behind ChatGPT have complex, sometimes surprising structures, and we don’t yet fully understand how they work.This approach ...

RT Jason Kwon (@jasonkwon)We’re fighting this overreach on user privacy. As @sama has mentioned before, we need a new form of privilege - AI privilege - given some of the kinds of conversations people are having with these tools today.Fittingly, Nils Gilman published an op-ed in the NYT discussing AI privilege just the other day. The conversation by conversation analysis necessary to provide that kind of respect highlights just how wild it is to ask for 20m conversations indiscriminately. ...

Also, we've made it easier to customize ChatGPT. You can pick from presets (Default, Friendly, Efficient, Professional, Candid, or Quirky) or tune it yourself. ...

GPT-5.1 is out! It's a nice upgrade.I particularly like the improvements in instruction following, and the adaptive thinking.The intelligence and style improvements are good too. ...

RT Greg Brockman (@gdb)Welcome @sk7037 to OpenAI!Incredibly excited to work with him on designing and building our compute infrastructure, which will power our AGI research and scale its applications to benefit everyone. https://t.co/GkZ5yHctBO ...

This is an important one, I think. AI progress and recommendations:https://t.co/Zy6J6bxYBI ...

The government has played a role in critical infrastructure builds. Our public submission (posted on our blog) shares our thinking and suggests ideas for how the US government can support domestic supply chain/manufacturing.This is very in line with everything we have heard from the government about their priorities. We think US reindustrialization across the entire stack--fabs, turbines, transformers, steel, and much more--will help everyone in our industry, and other industries (including us).To the degre ...

I would like to clarify a few things.First, the obvious one: we do not have or want government guarantees for OpenAI datacenters. We believe that governments should not pick winners or losers, and that taxpayers should not bail out companies that make bad business decisions or otherwise lose in the market. If one company fails, other companies will do good work.What we do think might make sense is governments building (and owning) their own AI infrastructure, but then the upside of that should flow to the g ...
