Here is a fact that should give every engineering leader pause: 96% of developers say they do not fully trust AI-generated code. They are using it anyway. Because it is fast, and deadlines are real. But they are shipping code they cannot verify. At scale, in critical systems, this is a ticking clock. Mistral shipped Leanstral on March 16, 2026. It is a different kind of answer to the AI code quality problem—not more guardrails, not better test generation, but formal mathematical proof. Leanstral generates proofs that your code is provably correct against formal specifications. That is a fundamentally different level of verification from “the tests pass.” ...
