Devstral Small 2
Analysis Summary
Devstral Small 2 is Mistral's coding-specialist small model, with an intelligence index of 17.4 and a coding index of 29.3. Its livecodebench score of 34.8% and terminal bench hard score of 16.7% are the strongest in the Ministral family, and its scicode of 28.8% reflects genuine coding competence for a model of this size. MMLU Pro of 67.8% indicates solid general knowledge alongside the coding focus.
For businesses, this model is best deployed in developer tooling, code review assistance, lightweight code generation, and IDE integrations where a small, fast, coding-oriented model is preferred over a larger general-purpose one. Its agentic index of 20.0 is modest, limiting its use in fully autonomous coding agents, but it can handle structured coding tasks reliably.
No pricing data is available, which makes direct cost comparison difficult. For teams building developer-facing tools or internal coding assistants where model size and specialisation matter, Devstral Small 2 is a strong candidate in its class. Teams needing stronger reasoning or agentic capability should look to larger models.
