About devstral2

Devstral 2 is a state-of-the-art, 123B-parameter open-source coding model, a dense transformer supporting a 256K context window. It achieves 72.2% on SWE-bench Verified, establishing it as one of the best open-weight models while remaining highly cost-efficient. Released under a modified MIT license, Devstral 2 sets the open state-of-the-art for code agents. Mistral Vibe CLI is a native, open-source command-line coding assistant powered by Devstral, designed to solve software engineering tasks autonomously by exploring, modifying, and executing changes across codebases using natural language.

How to Use

Users can access Devstral 2 via API, which is currently offered for free, or through self-hosted deployment on their own infrastructure with NVIDIA support. Mistral Vibe CLI can be installed directly in the terminal using a curl command (curl -LsSf https://mistral.ai/vibe/install.sh | bash) and then used as a native coding assistant.
