Mistral AI has released Devstral 2, a next-generation open-source coding model family consisting of the 123B-parameter Devstral 2 and the 24B-parameter Devstral Small 2. Alongside these models, the company introduced Mistral Vibe, a native command-line interface designed for end-to-end code automation.
- Devstral 2 achieves 72.2% on SWE-bench Verified and is up to 7x more cost-efficient than Claude Sonnet at real-world tasks.
- Devstral Small 2 scores 68.0% on SWE-bench Verified, runs locally on consumer hardware, and supports image inputs for multimodal agents.
- Mistral Vibe CLI provides an open-source terminal assistant with project-aware context, multi-file orchestration, and IDE integration via the Agent Communication Protocol.
- Devstral 2 is licensed under a modified MIT license, while Devstral Small 2 and Vibe CLI use the Apache 2.0 license.
The release aims to accelerate distributed intelligence by providing permissively licensed models that lower deployment barriers for developers and small businesses through compact sizes and local deployability.
