Swapping the earlier open-source LLM for Mistral's Codestral, with no infrastructure change, raised code completion accuracy from about 50% to 90% and developer adoption from 30% to 100%, with the roughly 50 client projects reporting productivity savings. Capgemini is now rolling out the full Mistral Code solution.","company":"Capgemini","industry":"Technology & Software","aiCapabilities":["Code Generation"],"technology":["Codestral"],"deployment":"Unknown","problemStatement":"Capgemini's regulated clients in aerospace, defence and the public sector need self-hosted AI solutions because strict privacy and data control prevent cloud offerings. Early open-source coding assistants had only 30% adoption because developers found about 50% accuracy insufficient, and legacy applications from the 1980s needed support in languages such as ADA, C and C++.","solutionApproach":"Capgemini replaced the earlier open-source LLM in its self-hosted coding assistant (RAISE for Private Software Engineering, also known as SovBox) with Mistral's Codestral, without infrastructure changes and keeping the IDE and CI/CD integrations. It is now rolling out the full Mistral Code solution, including Codestral Embed and Devstral for RAG and CI/CD integration.","businessValue":"The source reports developer adoption rising from 30% to 100%, code completion accuracy of 90% versus 50% for previous solutions, and about 50 client projects reporting productivity savings within 6 months. All figures are vendor-reported.","evidence":{"band":"high"},"sourceUrl":"https://mistral.ai/it/customers/capgemini/","dates":{"publishedAt":"2026-11-15T05:48:57.706Z","publishedAtSource":"pipeline","updatedAt":"2026-11-15T05:48:57.706Z"},"license":"Open for reading and citing with a link to https://findausecase.com/use-cases/capgemini-moves-its-self-hosted-sovbox-coding-assistant-to-mistral-s-codestral-raising-developer-adoption-from-30-to-100-across-about-50-client-projects.
