Mistral AI has announced a new generation of its Devstral model family, designed specifically to advance agentic coding capabilities. Devstral models are purpose-built for software engineering agents that autonomously plan, write, debug, and iterate on code. The release signals Mistral's continued investment in the competitive agentic-coding segment alongside offerings from Anthropic, OpenAI, and Google.
Mistral AI announced two Devstral updates focused on agentic coding workflows: Devstral Small 1.1 and Devstral Medium. Devstral Small 1.1 remains a 24B Apache 2.0 open model and reaches 53.6% on SWE-Bench Verified. Devstral Medium reaches 61.6%, is available through Mistral’s API, and supports private deployment and custom finetuning for enterprises.
