SAIR foundation announced that Mistral Large 4 inference and model access for its Open Math OS platform—a collaborative math research and scientific computing infrastructure—are sponsored by Mistral with zero data retention; teams can now apply.

The platform offers open frontier models (Kimi K3, DeepSeek V4.1 Flash, GLM 5.3 and more, with reasoning effort up to an "Ultramath" setting), a 24/7 cloud machine per project with 100+ math/science tools preinstalled, community-owned data sovereignty, and collaboration tooling. Ultramath runs parallel agents on one problem, sharing findings and returning proposed solutions, with Lean proofs and LaTeX write-ups produced in-chat for review.
