A first preview of something we expect to see a lot more of soon:Sebastien Bubeck (@SebastienBubeck):3 years ago we could showcase AI's frontier w. a unicorn drawing. Today we do so w. AI outputs touching the scientific frontier: https://t.co/ALJvCFsaieUse the doc to judge for yourself the status of AI-aided science acceleration, and hopefully be inspired by a couple examples! https://t.co/5pxuUp9x3r ...

New Codex model is a significant improvement!prinz (@deredleritt3r):METR (50% accuracy):GPT-5.1-Codex-Max = 2 hours, 42 minutesThis is 25 minutes longer than GPT-5. https://t.co/NgqG3E5LfB ...

Congrats to Google on Gemini 3! Looks like a great model. ...

The rate reduction in price per unit of intelligence has been thing I've most consistently underestimated the past couple of years.300x in a year is nuts!Chris (@chatgpt21):GPT-5.1 (Thinking High) is about 300 times cheaper per task than o3-preview (Low) while scoring only a few points lower on ARC-AGI-1.1 year later intelligence has gotten 300 times cheaper.This is why I can’t stand people who say “wahh the models too expensive” it will become https://t.co/VkfepKVTgV ...

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 ...

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. ...
