Devstral
Devstral is Mistral AI's model built specifically for coding tasks and software engineering agents, released as open weights alongside API access through Mistral's platform. It's designed to perform well on agentic coding benchmarks where a model needs to navigate a codebase and make multi-step changes, not just generate isolated code snippets.

A good fit for
- Developers building AI coding agents who want a model specifically tuned for agentic coding tasks
- Teams wanting an open-weight coding model they can self-host rather than relying solely on an API
- Projects needing multi-file, multi-step code changes rather than single code snippet generation
Not a good fit for
- General-purpose conversational tasks outside of coding, where Mistral's other models may be a better fit
- Teams wanting a proprietary, closed-weight model rather than an open-weight one
- Very simple, single-line code completion where a lighter model would suffice

About Devstral
Devstral is built specifically for coding-agent use cases, where a model needs to explore a codebase, make edits across multiple files and follow multi-step instructions, rather than just producing a single code snippet from a prompt.
Unlike Mistral's proprietary Large-tier models, Devstral is released as open weights under the Apache-2.0 license, letting developers download and self-host it in addition to accessing it through Mistral's API.
It's positioned to compete with other coding-focused open-weight models, aimed at teams building their own AI coding agents or tools who want a model specialized for that use case rather than a general-purpose model repurposed for coding.
