Devstral the listed price is an agentic large language model purpose-built for software engineering tasks. Rather than serving as a general-purpose assistant, it is architected to excel at tool use, codebase exploration, and multi-file editing—making it a natural fit for powering software engineering agents. The model ships as an FP8 Instruct variant with a the cataloged API limit context window, designed to handle large repositories and complex, multi-turn coding sessions. Mistral's approach positions Devstral the listed price as a direct competitor to proprietary systems in the coding agent space, with one version engineered to run locally on a laptop for developers who need offline, private workflows.

The model builds on Mistral's broader push into developer tooling, arriving alongside the Mistral Vibe CLI to let engineers invoke it directly from their terminal. Benchmark results show the 123-billion parameter model achieving 72.2% on SWE-bench Verified and 61.3% on the multilingual variant, with a 32.6% score on Terminal Bench the listed price—placing it among the strongest open-weight coding models in its class. A smaller 24-billion parameter variant extends this capability to resource-constrained environments, while still maintaining competitive SWE-bench scores. For enterprises with specialized requirements like extended context or domain-specific knowledge, Mistral offers direct engagement, signaling a path toward tailored deployments beyond the base instruct model.
