Mistral AI Releases Devstral Medium and Devstral Small 1.1 for Agentic Coding
Mistral AI, in collaboration with All Hands AI, has released two new agentic coding models: Devstral Small 1.1 (24B parameters, Apache 2.0, 53.6% on SWE-Bench Verified) and Devstral Medium (61.6% on SWE-Bench Verified, API-only). Devstral Medium is positioned as a cost-performance leader, claiming to surpass Gemini 2.5 Pro and GPT-4.1 at roughly one-quarter the price, priced at $0.4/M input and $2/M output tokens. Devstral Small 1.1 sets a new state-of-the-art among open models for code agents without test-time scaling, and supports both Mistral function calling and XML formats for broad agentic scaffold compatibility.
Mistral Announces Codestral 25.08 and Integrated Enterprise Coding Stack
Mistral AI has released Codestral 25.08, a code generation model update claiming +30% accepted completions, 50% fewer runaway generations, and improved FIM benchmark performance. The announcement also frames a full enterprise coding stack comprising Codestral (completion), Codestral Embed (code-specific retrieval), and Devstral (agentic workflows via OpenHands), all deployable on-prem or in VPC environments. Devstral Medium is reported to achieve 61.6% on SWE-Bench Verified, while Devstral Small (24B, Apache-2.0) reaches 53.6%. The pitch targets regulated industries blocked by SaaS-only competitors through self-hostable, air-gapped deployment options.
