Devstral 2Open-source CLI agent for developers who maintain real codebases
Devstral 2
Built for refactoring and understanding large repositories — not toy examples. Use open-source AI models through a native CLI workflow to make real changes across real codebases.
Top-tier performance on real-world coding benchmarks, with strong results on multi-file refactors and repo-level reasoning.
Install the Vibe CLI and start refactoring a real repo in minutes.
Why developers choose Devstral
Devstral models are designed to understand and modify large, multi-file projects. They reason across architecture, dependencies, and long-term context — not just single snippets.
Describe the change you want to make to your repo in natural language. The agent handles execution across files.
Both Devstral 2 and Devstral Small 2 are released under permissive licenses. Run them locally, deploy on-prem, or integrate them into your own workflows without lock-in.
Devstral models achieve strong coding performance with significantly fewer parameters. Lower compute costs, faster iteration, and practical deployment on real hardware.
