Mistral Vibe: Coding Agents

Founded 2024|Paris, France|51-200 people|Free OSS CLI + per-token Devstral inference / Le Chat Pro

What is Mistral Vibe?

Mistral Vibe is Mistral AI's official open-source CLI coding agent. It runs in the terminal and ships with the Devstral 2 model — Mistral's state-of-the-art open code-agent model that scores 72.2% on SWE-bench Verified and is up to 7× more cost-efficient than Claude Sonnet on real-world coding tasks.

Vibe 2.0 (launched January 2026) added custom subagents, slash-command skills, Model Context Protocol (MCP) support, and a clarification system that asks before it acts when intent is ambiguous. The interactive chat interface includes tools for file manipulation, code search, version control, and command execution. Devstral 2 weights are released under Apache 2.0 — fully open and self-hostable.

Pricing is free for the open-source CLI; users pay per-token Devstral inference at standard rates (no markup) or pay for Le Chat Pro subscriptions which include enterprise features. Vibe is positioned as the European, cost-conscious alternative to Claude Code and OpenCode — capable on routine work but trailing frontier closed models on complex multi-file refactors.
