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.
