project name: Le Bac à Sable

Add a sandbox to Le Chat to supercharge its capabilities. Iterate on your files and datasets directly in your sandbox and deploy your product—all from Le Chat.

Le Bac à Sable attaches a Linux container sandbox to every chat, enabling the model to create, modify, and execute files during the conversation in a stateful way. No more document copy jungle, in modify your file in place. While Mistral Medium excels at coding tasks, the native code interpreter tool has limitations (one shot input/output). Le Bac à Sable is especially useful when working with medium to large files or transferring them between tools.

**Examples:**

- Ask Le Chat to download and clean a dataset. Le Bac à Sable’s MCP provides a tool to run commands for that.
- Build a full-stack app, iterate on the generated code, and deploy it—all from Le Chat.
- Convert video or audio files to your desired format.
