French startup Mistral AI has released Devstral 2, an open-weights coding model designed to work alongside autonomous software engineering agents. With a score of 72.2 percent on SWE-bench Verified, this new model is gaining attention within the industry as a promising alternative to proprietary options.
Mistral AI released Devstral 2, an open-weights coding model designed for autonomous software engineering agents. Devstral 2 achieved a score of 72.2% on SWE-bench Verified, a benchmark that tests AI systems' ability to solve real GitHub issues. The model is released under a modified MIT license to encourage wider adoption and collaboration within the developer community. Devstral 2 has a companion development app called Mistral Vibe, which allows developers to interact with the model directly in their terminal. Devstral Small 2 runs locally on consumer hardware without requiring an internet connection, making it an attractive option for developers.
In a move that has been gaining significant attention within the AI community, French startup Mistral AI recently released Devstral 2, an open-weights coding model designed to work alongside autonomous software engineering agents. This new model has already made waves by achieving a score of 72.2 percent on SWE-bench Verified, a benchmark that tests whether AI systems can solve real GitHub issues.
The release of Devstral 2 comes as part of a broader effort by Mistral AI to provide developers with more accessible and cost-effective alternatives to proprietary coding models. By releasing the model under a modified MIT license, the company aims to encourage wider adoption and collaboration within the developer community.
One of the most notable features of Devstral 2 is its companion development app, known as Mistral Vibe. This command-line interface (CLI) allows developers to interact with the Devstral models directly in their terminal, using a similar approach to other popular tools such as Claude Code and OpenAI Codex. The app boasts several key capabilities, including the ability to scan file structures and Git status, make changes across multiple files, and execute shell commands autonomously.
While some may view AI benchmarks with a healthy dose of skepticism, it's worth noting that many experts within the industry closely follow how well models perform on SWE-bench Verified. This benchmark presents AI systems with 500 real software engineering problems pulled from GitHub issues in popular Python repositories, requiring them to read the issue description, navigate the codebase, and generate a working patch that passes unit tests.
Devstral Small 2, which boasts 24 billion parameters and scores 68 percent on the same benchmark, is also notable for its ability to run locally on consumer hardware without requiring an internet connection. This makes it an attractive option for developers who need access to AI-powered coding assistance without sacrificing performance or reliability.
The emergence of Devstral 2 as a promising open-weights option marks an exciting development in the ongoing quest for more accessible and cost-effective AI solutions. As the AI community continues to explore new approaches and technologies, it's likely that we'll see further innovations from Mistral AI and other startups like them.
