Mistral Releases Devstral 2 (72.2% SWE-Bench Verified) and Vibe CLI (mistral.ai)

Mistral has announced the release of Devstral 2, an advanced open-source coding model family that includes two versions: a 123-billion parameter model and a smaller 24-billion parameter variant. Achieving a score of 72.2% on SWE-bench Verified, Devstral 2 establishes itself as a state-of-the-art model for code generation, significantly outperforming competitors while being up to 7x more cost-efficient than Claude Sonnet. Both models are available under permissive licenses to foster innovation and can be easily deployed on consumer hardware, making them accessible for developers, small businesses, and hobbyists. In addition to Devstral, Mistral has unveiled the Vibe CLI—an interactive command-line tool designed to enhance code automation using natural language. Vibe CLI enables users to explore and modify their codebase with features like smart references, project-aware context, and multi-file orchestration, all geared towards optimizing software engineering workflows. With these releases, Mistral not only pushes the boundaries of open-source AI but also provides essential tools to streamline coding tasks, empowering the developer community to leverage AI's potential for improved productivity and efficiency.
