Here’s a quick walkthrough of Open Math OS API keys and when to use each one.

Model key → access open frontier models
Platform key → access all platform features

Enjoy your research with Open Math OS!

[Mistral AI @MistralAI]

Mistral Large 4 joins the model lineup on Open Math OS.

1.05T open weights, 1M context, live today for approved teams.

Open Math OS is a research workspace where mathematicians and AI agents work on shared projects, built only on open models so the community can inspect and run them, and with the community in control of its own data.

More open frontier models in the lineup means more choice for every team.

[SAIR @SAIRfoundation]

More than 800 research teams are using Open Math OS.

Approved teams get free compute for open frontier models and access to our scientific computing cloud.

We’ve given everyone a fresh reset. Keep doing great research!

API key early access is live on Open Math OS.
Model key → open frontier models
Platform key → full platform access

We’ll keep making it better.

We’ve given everyone a fresh reset. Enjoy!

Terence Tao on where AI has landed in mathematics: not the whole field, but one of its hardest activities, solving problems in pure mathematics. Why that’s a key part of what mathematicians do, and why it isn’t the whole picture.

[SAIR @SAIRfoundation]

Terence Tao on the misalignments of AI and math: when an AI solves a problem, the understanding that used to come with solving it can be lost. There's no author to call, no one to invite to give a talk. Why that matters, and what we build next.

[SAIR @SAIRfoundation]

Terence Tao on the next phase of AI in mathematics: punching your favorite problem into an AI is the unimaginative use. The larger frontier is humans prompting AI in creative ways. That is Math 2.0, and it’s coming soon.

[SAIR @SAIRfoundation]

Terence Tao’s UCLA talk on Math 2.0 explores what comes after proof abundance.

More proofs don’t mean more understanding. We need better questions, deeper insight, and open infrastructure.

Our Open Math Model is building toward that vision: https://t.co/2xMci7oVql

Yu Deng: Open Math Model will bring transparency, data control, and traceable chains of thought to mathematical research. Even if open models take a few extra months to reach the capabilities of closed-source options, having access to transparent tools is far more beneficial for the math community's long-term growth, learning, and idea development.

[SAIR @SAIRfoundation]

Yu Deng questions the misalignment between mathematicians and AI companies: researchers contribute public knowledge and user input, while companies build private models, charge for access, and claim credit for solving open problems.
