Mistral AI Drops New Open-Source Code Models
10 Dec, 2025
Summary
- Mistral AI released Devstral 2, new coding models, and Vibe CLI.
- Devstral 2 is 123B parameters with 256K context, Devstral Small 2 is 24B.
- Devstral 2 has revenue restrictions; Devstral Small 2 is Apache 2.0 licensed.
French AI startup Mistral AI has released Devstral 2, a new pair of models optimized for software engineering tasks, alongside Mistral Vibe, a command-line interface agent. The company also recently debuted its Mistral 3 LLM family for edge devices. These releases aim to compete with proprietary systems by enhancing developer experience while maintaining an open-source ethos.
The Devstral 2 model boasts 123 billion parameters and a 256K-token context window, achieving 72.2% on the SWE-bench Verified benchmark. Its smaller counterpart, Devstral Small 2, with 24 billion parameters, scores 68.0% on the same benchmark, positioning it as a strong open-weight model for its size.
Mistral's licensing strategy presents a key distinction: Devstral Small 2 is freely available under the Apache 2.0 license. However, the more powerful Devstral 2 model is subject to a modified MIT license, prohibiting companies with over $20 million in monthly revenue from using it for free, necessitating a commercial license.
