Devstral 2

Devstral 2 is positioned as a 123-billion-parameter open-weight coding model, making it a substantial option for repository-scale agent workflows. Its reported SWE-bench Verified score of 72.2% provides a concrete signal of software-engineering performance, while its support for codebase exploration and multi-file orchestration suits tasks that require understanding several files and coordinating changes across them.

The model is intended for coding assistants and other tool-driven software workflows, where it can inspect code context and help manage complex edits. Its reported 256K-token context window supports broad repository and long-document handling, but teams should verify the exact serving configuration and benchmark methodology against primary documentation before making deployment decisions.
