On May 28, 2026, Mistral released an announcement titled “Vibe gets to work.” One sentence sums it up: Le Chat is now Vibe, a single agent and license for work and code, with every conversation, setting, and subscription carried over. If you used Le Chat, nothing is lost; but the interface, vocabulary, and feature organization have changed. This lesson provides the mappings.

Three Modes in One App

Vibe always opens at chat.mistral.ai and offers three modes, which you select in the sidebar.

ModePurposeWhere
WorkDelegate long, multi-step tasks across your tools: email, calendar, deep research, drafting deliverables, scheduled tasksWeb and mobile
CodeDevelopment: from request to merged change, with the Vibe CLI, VS Code extension, and Vibe Code Web for remote sessionsTerminal, editor, web
ChatThe legacy Le Chat experience, kept for existing use casesWeb and mobile

In Work mode, the documentation specifies that quick conversations happen in the same place by switching the “fast/think” toggle to fast. Work breaks down a request into steps, selects tools, and asks for confirmation before sensitive actions.

Where Le Chat Features Went

The Vibe documentation provides the equivalences itself. Le Chat agents now correspond to skills, which you invoke with @. Memories correspond to the knowledge base. Deep search becomes the “Deep Research” skill. The code interpreter becomes a native sandbox in Work, reserved for paid plans. Work mode also relies on connectors (email, calendar, Slack, Notion, GitHub, Google Drive, SharePoint…), libraries of indexed documents, files and canvas, and web search.

If you are following any of our courses written before the name change—Advanced Le Chat, Le Chat and MCP, Le Chat Enterprise—keep this mapping table handy: the concepts remain valid, but menus and names may have changed.

Plans

Plans now bear the Mistral name and provide access to Vibe: Free, to explore; Pro, at $14.99 per month on the USD pricing grid, which includes API credits; Team; and Enterprise, with custom SLAs, dedicated support, and private deployments. Verified students can get Mistral Pro for $5.99 per month. According to the pricing page, the free plan gives limited access to Vibe, including the latest models, conversation, search, creation, and agentic coding in the terminal.

What to Do If You Train Users

Update your materials on three points: the product name (Vibe, no longer Le Chat), entry by mode (Work for deep work, Code for development, Chat for the legacy experience), and feature equivalences (skills, knowledge base, Deep Research). Reassure your users about continuity: history, settings, and subscriptions have been carried over.
