As AI takes on longer, higher-stakes tasks, we want models to carry beneficial and safe behavior into new domains beyond their training—and maintain it under pressure.

That’s the idea behind our new research on training models to be broadly and persistently beneficial. https://t.co/6Yw45s1RRq

Together with researchers at Boston Children’s Hospital and Harvard, we published a study in NEJM AI showing how o3 Deep Research helped clinicians revisit previously unsolved rare pediatric disease cases, and find answers for families who had waited years.

OpenAI frontier models and Codex are now generally available on AWS, giving enterprises a new way to build on Amazon Bedrock with OpenAI through the security, compliance, and governance workflows they already use.

This is also the beginning of a broader expansion of OpenAI capabilities on AWS, including future availability for cybersecurity capabilities like Daybreak.

Today, we share a breakthrough on the planar unit distance problem, a famous open question first posed by Paul Erdős in 1946.

For nearly 80 years, mathematicians believed the best possible solutions looked roughly like square grids.

An OpenAI model has now disproved that belief, discovering an entirely new family of constructions that performs better.

This marks the first time AI has autonomously solved a prominent open problem central to a field of mathematics.

Step away from your laptop. Keep building with Codex on your phone.

Codex keeps working on your computer, with your files and project context still in place.

Pocket-sized access. Full Codex working state.

Want to (officially) use Codex at work?

Send this post to your CTO to bring your team to Codex. Eligible enterprise customers who switch in the next 30 days get 2 free months of Codex usage for new users.

Codex grew programmatic policies with no neural nets: max score on Breakout, and SOTA-level scores on MuJoCo.

Maybe heuristics were not too weak. Maybe they were just too expensive to maintain. Maybe it's the next paradigm.

This is the the quote I've been citing a lot recently.

[OpenAI @OpenAI]

It's never been easier to do everyday work with Codex.

Choose your role, connect the apps you use every day, and try suggested prompts.

Codex helps with everything from research and planning to docs, slides, spreadsheets, and more.

We’re talking about Goblins.

Codex just got a lot more powerful.

Computer use, in-app browser, image generation and editing, 90+ new plugins to connect to everything, multi-terminal, SSH into devboxes, thread automations, rich document editing. Learns from experience and proactively suggestions work. And a ton more.

[OpenAI @OpenAI]

You can just build things.

[OpenAI @OpenAI]

Over 300M people use ChatGPT to learn how to do something every week.

More than half of US ChatGPT users say it enables them to achieve things that previously felt impossible.

These are just a few stories of what they are building.

Introducing the Codex app—a powerful command center for building with agents.

Now available on macOS.

1/N I’m excited to share that our latest @OpenAI experimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO).

lmsys is clearly the most important, if I could give one piece of advice to all labs out there it would be to prioritize lmsys. If you’re not maximizing user value then what are you even doing?
