Excited to share details on two of our longest running and most effective safeguard collaborations, one with Anthropic and one with OpenAI. We've identified—and they've patched—a large number of vulnerabilities and together strengthened their safeguards. 🧵 1/6
We’ve been working with the US Center for AI Standards & Innovation and the UK AI Security Institute to raise the bar on AI security. From joint red-teaming to end-to-end testing, these voluntary collaborations are already delivering real-world security improvements for widely…
I am looking for students and collaborators for several new projects at the intersection of AI, the economy, and society. If you are interested, please fill out this form! forms.gle/DNrKPeiJjdi4Vg…
It’s rare for competitors to collaborate. Yet that’s exactly what OpenAI and @AnthropicAI just did—by testing each other’s models with our respective internal safety and alignment evaluations. Today, we’re publishing the results. Frontier AI companies will inevitably compete on…
No single person or institution should define ideal AI behavior for everyone. Today, we’re sharing early results from collective alignment, a research effort where we asked the public about how models should behave by default. Blog here: openai.com/index/collecti…
We just launched GPT-5! There has been an unbelievable amount of safety work that went into this model, from factuality, to deception, to brand new safety training techniques. More details and plots in the 🧵
gotta say I'm excited about this: GPT-5 chain of thought access for external assessors (@apolloaievals too!) is an evaluation win (on the heels of the process audit that @METR_Evals engaged with us on for gpt-oss!) that I'm proud of us @OpenAI for and thankful for the collabs!

We’ve activated our strongest safeguards for ChatGPT Agent. It’s the first model we’ve classified as High capability in biology & chemistry under our Preparedness Framework. Here’s why that matters–and what we’re doing to keep it safe. 🧵

FutureHouse's goal has been to automate scientific discovery. Now we used our agents to make a genuine discovery – a new treatment for one kind of blindness (dAMD). We had multiple cycles of hypotheses, experiments, and data analysis – including identify the mechanism of action.
Proud of our team for pushing forward transparency with this initial step!

Evaluations are essential to understanding how models perform in health settings. HealthBench is a new evaluation benchmark, developed with input from 250+ physicians from around the world, now available in our GitHub repository. openai.com/index/healthbe…
The First Workshop on Sociotechnical AI Governance at CHI 2025 (STAIG@CHI’25) is less than a week away! We’re super excited to hold a panel with some amazing speakers to discuss why a sociotechnical approach to AI governance is so important. Join us in Yokohama or online.
