# Run Mistral Vibe in Palette Desktop workspaces

> Run Mistral Vibe in Palette Desktop with Mistral Medium or Devstral Small, using an API key billed directly to your own Mistral account for each chat.

Mistral's Vibe agent, run inside Palette Desktop through the `vibe-acp` CLI. Pick it per chat like any other agent.

## Setup

1. In a chat, choose **Mistral Vibe** as the agent. If you don't have it yet, Palette installs it for you in one click from Settings. No terminal needed.
2. Choose **Sign in with Mistral** and complete the browser flow. This provisions a Mistral **La Plateforme** API key and stores it locally.

That's it. See below for what the sign-in actually sets up, because it is not what most people expect.

## Models

| Model              | When to use                                   |
| ------------------ | --------------------------------------------- |
| **Mistral Medium** | The general-purpose default.                  |
| **Devstral Small** | A lighter model tuned for coding-style tasks. |

You can set either as your default and switch per chat. For more on Mistral's models, see [Mistral's model overview](https://docs.mistral.ai/getting-started/models/models_overview/).

## Usage & billing

"Sign in with Mistral" is **not** a consumer Le Chat subscription. It provisions a Mistral **La Plateforme API key** and stores it in `~/.vibe/.env` as `MISTRAL_API_KEY`. Mistral Vibe owns this local credential; Palette does not copy it into your operating system's keychain. Access is metered by tokens and billed to your own Mistral La Plateforme account. To raise limits or manage payment, use your Mistral account. Palette does not add a markup on Mistral usage.

## Limits & notes

* Palette Desktop does not currently guarantee that Mistral loads `AGENTS.md` automatically. Mention the file in your prompt when Mistral should use those workspace instructions. See [Working with CLAUDE.md and AGENTS.md](/docs/desktop/claude-md-and-agents-md).
* **Plan mode is available with [Claude Code](/docs/desktop/claude-code) and the Palette agent.** Slash commands are specific to Claude Code. Neither is available for Mistral.
