## What the story says

Capgemini replaced the open-source model in its self-hosted software engineering assistant with Mistral's Codestral to give developers code completion and chat assistance inside their IDEs. The assistant serves regulated clients in aerospace, defense and public sectors that require self-hosted AI, and covers modern and legacy programming languages.
