AnimaAnandkumar · x · 2026-10-07
TorchLean, a Caltech project with Anima Anandkumar, was selected for the 2026 AI for Math Fund, backed by a record $17.1M from XTX Markets ($35.1M total) with 22 winners chosen from 400+ applications across 50 countries.
TorchLean is a Lean 4 codebase for neural network specification, execution, and verification — covering autodiff, floating-point semantics, verification, and GPU execution. It has already uncovered bugs and semantic mismatches across major ML stacks, and teams at major companies and U.S. national labs are using it for ML verification. Next steps: formally verified GPU execution and kernel verification.
