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.
Mistral introduced Devstral 2, a 123B coding model, and Devstral Small 2, a 24B variant for lighter deployment. The company reports 72.2% and 68.0% on SWE-bench Verified, respectively, with permissive open-source licensing. It also launched Mistral Vibe CLI, an open-source terminal agent for codebase exploration, multi-file edits, command execution, and IDE integration.
A community benchmark of Qwen 3.6 27B on DeepSWE yielded a score of 1.79% (18/20th place), slightly outperforming Haiku 4.5. Run on a single RTX 6000 Blackwell GPU via vLLM with reasoning enabled, the test averaged 32 minutes and 44k output tokens per task. The author notes that while Qwen 3.6 27B represents a 'poor man's local SOTA,' the massive gap compared to frontier closed models suggests local LLMs are struggling to keep pace in complex coding.
