Formalization acts as an external, machine-checkable trust boundary: the value of AI-assisted mathematics comes not from the model's fluency but from the fact that a proof assistant enforces strict formatting so outputs become mechanically verifiable. The verification layer, not the generator, carries the accountability.
Offers a concrete precedent for placing a strict, deterministic checker at the end of an AI generation pipeline rather than trusting model self-report or human reading, which is exactly the missing trust boundary in most agentic systems that produce free-form artifacts.
Any generative pipeline can be made dependable by constraining outputs to a formal grammar and gating them through a deterministic verifier, shifting the engineering cost from 'trust the model' to 'pay the formalization cost up front'.
Formalization and verification tools require strict formatting, making mathematics more rigorous and accountable.
AI models and formal verification tools like Lean provide new ways to check proofs, though they require extreme precision.
