Mistral Vibe

Introduction

Mistral Vibe is Mistral AI's open-source agentic coding assistant — terminal-native, IDE-integrated, and cloud-capable, powered by Devstral 2, Codestral, and Codestral Embed. Launched on December 8, 2025 under an Apache-2.0 license, it started as a CLI-only tool and now runs in your terminal, as a VS Code or JetBrains extension, via the Zed editor, and as a remote agent in Le Chat.

Vibe reads and edits files, executes shell commands, browses codebases, orchestrates subagents for parallel work, and extends its capabilities through a skills system and MCP server configuration.

It's the European sovereign alternative to US-hosted coding agents.

Devstral 2 runs via Mistral API or as a self-hosted open-weight model.

As of May 2026 (v2.10.1, 52 releases), Mistral Vibe supports async agents for work that persists beyond your session, remote agents powered by Mistral Medium 3.5, tab-to-complete for multi-line code completions, voice mode, and AGENTS.md custom instructions. It is available on Pro, Team, API, and Enterprise plans.

Key Features

• Multi-model architecture: Devstral 2 (purpose-trained for agentic coding), Codestral (code generation and completions), and Codestral Embed (code retrieval and search)
• Subagent orchestration: spawn and coordinate specialised sub-agents for research, implementation, testing, and exploration in parallel
• Skills system: package reusable agent behaviours as composable units, with custom slash commands and tool permissions
• Native IDE extensions: VS Code and JetBrains extensions with intelligent completions, context-aware chat, and inline code editing
• Zed integration: via the Agent Client Protocol (ACP)
• Async agents: extended autonomy and parallel execution beyond your active session
• Remote agents: powered by Mistral Medium 3.5 — run coding agents in a cloud sandbox from Le Chat, the CLI, or via /teleport
• Tab-to-complete: multi-line code completions tailored to your codebase
• Voice mode (experimental): dictate input using your microphone
• MCP server configuration: extend Vibe with external tools via HTTP, streamable HTTP, or stdio transports
• Custom agents and AGENTS.md : create custom agent profiles with --agent and add project-specific or user-level instructions
• GitHub Actions integration: action.yml in the repository for CI/CD automation
• Open-source: Apache-2.0 license, 52 releases, active community contributions
• Self-hostable: Devstral 2 is an open-weight model — deploy on-premises or in a VPC for full data sovereignty

Terminal-Native CLI

The core of Mistral Vibe is a conversational CLI built for software engineering. It reads, writes, and patches files, executes shell commands in a stateful terminal, recursively searches code with ripgrep, manages a todo list, and asks interactive clarifying questions. The CLI features autocompletion for slash commands and file paths, persistent command history, beautiful themes, and keyboard shortcuts for tool output, todo view, and debug console.

Vibe supports multiple built-in agent profiles: default (requires tool approval), plan (read-only for exploration), accept-edits (auto-approves file changes), and auto-approve (full autonomy). You can create custom profiles with TOML configuration files.

Subagent Orchestration

Vibe's subagent system lets the main agent delegate tasks to specialised sub-agents that run independently. The built-in explore sub-agent handles codebase exploration, and you can create custom sub-agents with agent_type = "subagent" in your configuration. Sub-agents prevent context overload by offloading parallel work — one sub-agent can research while another implements, while a third runs tests.

Skills System

Vibe follows the Agent Skills specification for skill format and structure. Skills are defined in directories with a SKILL.md file containing YAML frontmatter metadata. They can add new tools, custom slash commands, and specialised behaviours. Skills are discovered from multiple locations: custom paths, the project's .vibe/skills/ directory, the standard .agents/skills/ path, and the global ~/.vibe/skills/ directory.

IDE Extensions

Mistral Vibe ships native extensions for VS Code and JetBrains IDEs with intelligent code completions, context-aware chat, and inline code editing directly in the editor. For Zed, integration is available via the Agent Client Protocol (ACP), with setup instructions in the repository . Vibe is no longer a terminal-only tool — developers can work entirely from their preferred IDE.

Async and Remote Agents

Async agents let Vibe keep working after you close the session — useful for long-running tasks like migrations, large-scale refactoring, or batch testing. Remote agents, announced April 29, 2026, are powered by Mistral Medium 3.5 and run in a cloud sandbox within Le Chat via the Vibe Code Workflow. You can start a session from Le Chat, send a prompt from the CLI with & <prompt>, or /teleport an in-progress local session to the cloud.

Model Architecture

Mistral Vibe uses a trio of Mistral's coding models:

• Devstral 2: purpose-trained for agentic coding — the primary reasoning model for multi-step software engineering tasks
• Codestral: code generation and fill-in-the-middle completions, powering tab-to-complete
• Codestral Embed: code retrieval and semantic search for codebase navigation

All three can be accessed via Mistral API or self-hosted, giving enterprises full control over data residency and infrastructure.

MCP and Extensibility

Vibe supports the Model Context Protocol (MCP) for connecting to external tools and data sources. Configure MCP servers via config.toml with HTTP, streamable HTTP, or stdio transports. MCP tools are named using the {server_name}_{tool_name} pattern and can be configured with permissions like built-in tools. This ecosystem lets Vibe integrate with databases, APIs, documentation sources, and custom internal tools.

Pricing and Availability

Mistral Vibe is available on four tiers:

• Pro ($14.99/month): higher limits and priority access for individual developers
• Team ($24.99/user/month): shared usage for small development teams
• API: programmatic access to Devstral 2 ($0.1/M input tokens, $0.3/M output tokens), Codestral, and Codestral Embed
• Enterprise: custom deployments, fine-tuning, dedicated support, VPC/on-premises hosting

The Pro plan ($14.99/mo) is the Le Chat Pro subscription, which includes full Vibe CLI access. The CLI is free to install and use with your own API key. The full source code is available on GitHub under Apache-2.0.

Use Cases

• Code generation and editing: production-ready code from natural language, intelligent refactoring across files and modules
• Testing: auto-generated tests that evolve alongside the codebase
• Code review: context-aware feedback and early issue-catching
• Legacy migration: whole-codebase translation without losing business logic
• Performance optimization: identifies bottlenecks and suggests improvements
• CI/CD automation: GitHub Actions integration and programmatic mode for scripting
• Code documentation: automatically maintained inline comments, API docs, and architectural overviews
