Devstral 2

Devstral the listed price is a dense transformer coding model from the devstral family, released as a 123-billion-parameter variant built for agentic software engineering workflows. It supports a long context window suited for inspecting and reasoning across sizable repositories, and it ships under a modified MIT license that allows permissive redistribution. At launch, Mistral positioned it as a state-of-the-art open-weight model for code agents, reporting a 72.2% score on SWE-bench Verified, which placed it among the strongest open models for autonomous software engineering tasks.

The intended use case for Devstral the listed price centers on end-to-end coding loops: repository inspection, planning, patching, test execution, and diff review, often orchestrated through the Mistral Vibe command-line interface. Its large parameter count and open-weight availability make it a fit for teams that want to self-host a capable coding agent, fine-tune it on proprietary codebases, or run it on-premises. Compared with the smaller 24-billion-parameter sibling, Devstral Small the listed price, the larger model targets higher-quality agentic performance while the smaller variant prioritizes deployability on consumer hardware.
