Mistral: Devstral Small 1.1
Analysis Summary
Devstral Small 1.1 is Mistral's lightweight developer-focused model, designed for coding and agentic tasks with tool use and function calling built in. Its intelligence index sits at 9.3 and agentic index at 17.2, placing it firmly in the capable-but-not-frontier tier. Livecodebench at 0.254 and GPQA at 0.414 confirm it handles routine coding tasks but struggles with harder reasoning problems.
For businesses, this model fits well in cost-sensitive coding pipelines, automated code review, or lightweight agentic scaffolding where a small, fast model is preferable to a large expensive one. The file input modality adds some document handling utility. It is not suited to complex multi-step reasoning or high-stakes client-facing content.
At $0.10 per million input tokens and $0.30 output, it is one of the most affordable tool-capable models available. Teams running high-volume coding automation or IDE integrations will find strong value here, provided they stay within its capability ceiling.
