How Formal Verification Stops AI Reward Hacking | Theorem

Theorem aims to make formal verification practical for AI by automating proof generation and fast-checking, targeting inescapable sandboxes by year-end.

  • Proofs don't scale by hand: Jason Gross's PhD work showed formal verification needs 10-100x more lines of proof than code, requiring scarce PhD-level engineers.
  • Theorem's fix: hide the proof assistant**: Developers write normal code and property-based tests; Theorem auto-generates the theorem statement and lets AI models write the proof, while Theorem handles fast proof-checking.
