The math community deserves its own AI system.
Introducing Open Math OS: the infrastructure for Math 2.0.
Open models and AI agents. 24/7 cloud compute with 100+ tools. The community controls its data.
Compute is free for approved teams. Apply now:
openmathmodel.org/
Reset coming!
Some teams have already reached their weekly usage limits on Open Math OS, so we’re resetting weekly usage for everyone. Keep doing great math!

Terence Tao: Speed is not the only thing we want to optimize
Technology is rarely as simple as being pro or anti.
Finding the balance means combining the speed of AI with some slower ways of doing science, building communities, and retaining human understanding.
Yu Deng: Human and AI are co-evolving
By learning from humans, AI generates new ideas that researchers can learn from and build upon—creating a co-evolving relationship between human intelligence and artificial intelligence.
Yu Deng on the reason we do math: One key reason is to understand both our physical reality and the abstract math world. AI creates new boundaries between questions that have proofs and proofs that humans actually understand.
Terence Tao on building Open Math Model: Big tech used to give Mathematicians useful tools. But recent events show that community-driven models are necessary to ensure AI aligns with the mathematical community.
Fields Medalists Terence Tao and Yu Deng discuss why understanding matters more than answers, how credit and citations hold up when machines build on centuries of human work, and why SAIR launched Open Math OS and Open Math Model.

One month ago, we announced the Open Math Model initiative. Today, we’re launching Open Math OS.
Thank you to our launch partners @huggingface, @leanprover, @cscsch, and @EPFL
We’ve been building at full speed, and we’ll keep improving it with you.
