What you'll learn

Mistral Vibe is a terminal-native AI coding agent that can autonomously refactor large codebases, write documentation, and open pull requests without human intervention.
The agent can run parallel tasks in the cloud and continue working even when you close the tab or leave your computer.
Vibe integrates with VS Code and includes subagents, skills, and MCP connectors to handle complex coding tasks.

Frequently asked questions

What exactly did Mistral Vibe do with the 50,000-line codebase?

The agent refactored an entire directory, updated all cron files, rewrote the documentation, and opened a pull request, all without human intervention.

How does the cloud feature of Mistral Vibe work?

You can push a coding task to the cloud, allowing parallel agents to execute the task asynchronously while you are away or doing other things.

Where can you use Mistral Vibe besides the terminal?

Vibe also works directly in VS Code, so you can use agent capabilities within your standard code editor.

Who should wait before using Mistral Vibe?

The video mentions that certain users should wait, with more details about this advice provided later in the video.

Description from the channel

Get started with Mistral Vibe (my custom link): https://mistr.al/vibe-sirajraval-yt . Vibe runs through a Le Chat Pro or Team subscription, and the CLI is part of it. I installed Mistral's terminal-native coding agent, handed it my real 50,000-line codebase, pushed the session to the cloud, and physically walked away. It refactored an entire directory, updated every cron file, rewrote the docs, and opened a pull request while I wasn't at my desk.
