Mistral introduces Devstral 2, a new family of models for writing and orchestrating code, and Mistral Vibe, a native CLI that turns your terminal into a software engineering assistant. If you're interested in automating real tasks in projects, this shifts the landscape for developers, small teams, and anyone wanting to run models locally.
What is Devstral 2 and Devstral Small 2
Devstral 2 is a dense model with 123B parameters and a context window of 256K tokens, released under a modified MIT license. Devstral Small 2 is the smaller variant with 24B parameters, under Apache 2.0, designed to run on consumer hardware or on-prem environments.
Why does it matter? Because both are open source, permissive, and optimized for code agents: they can explore codebases, understand dependencies, and make changes that touch multiple files while keeping architectural context.
Devstral Small 2 also supports image inputs, fast inference, and private on-device runs — ideal for prototypes or teams that need privacy and low latency.
