AI Broke Half the Case Against Formal Verification

The 1979 objections are collapsing on proof labor and hardening on specifications, exactly where developers now need judgement.

An unreleased model jumped a 50-year-old bound from 41.6% to 67.2% inside Claude Code, with a machine-checked proof.

Math's AI moment shows capability lands wherever verification is cheap, public, and machine-checkable.

Astra's Lean-verified proofs are real, but the token bill and a rival model's one-day replication tell the bigger story.

The proof-oriented language never went mainstream, but its extracted C runs in Firefox, Python, Windows, and the Linux kernel.

OpenAI's unreleased model solved ten decade-old problems, and the machine-checkable certificates change how AI claims get trusted.

$OpenAI Disproved an Erdős Conjecture, and the Math Checks Out$

Named mathematicians verified the counterexample — the first credible autonomous AI research result, seven months after a false alarm.

An AI-assisted Lean proof of False slipped past both the official kernel and the independent nanoda checker.

Inside Lean soundness bug #14576, the one-hour fix, and why machine-checked now comes with a patch cadence.

Encode a scheduler's invariants in Z3, get a counterexample, then a machine-checked proof for every input.

A formally verified CSG kernel in Lean 4 shows where trust in machine-written code actually lands.

The ICM 2026 lecture reframes AI-for-math as a pipeline problem software teams will recognize immediately.

His ICM 2026 lecture on Goodhart's law and verification bottlenecks maps directly onto AI code generation.

Twenty independent Codex harnesses, Lean gates, and heavy tool sandboxes show how multi-agent work actually scales.
