The story
A global system integrator with 350,000 employees across 40+ countries serves clients in highly regulated sectors like aerospace, defense, and the public sector.
Strict data sovereignty rules prevented the use of cloud-based AI, while initial open-source attempts stalled at 30% adoption due to poor accuracy. Developers managing legacy applications from the 1980s found these tools insufficient for critical languages like Ada and C++.
Capgemini deployed a self-hosted engineering assistant powered by Mistral's Codestral model to satisfy privacy mandates. The team swapped the underlying model into existing IDE and CI/CD pipelines without disrupting established workflows or infrastructure. Extensive developer coaching accompanied the technical rollout to ensure effectiveness across both modern and legacy codebases.
Scope & timeline
- Developer adoption increased from 30% to 100%
Quotes
