Mistral Vibe: Opening a Session No Longer Waits on the Model Catalog

Mistral VibeNov 10, 2026View original changelog

Opening a session in Mistral Vibe no longer fetches the model catalog. The catalog is cached on disk and refreshed in the background, and running sessions pick up the refresh when their turn ends, so sessions open faster.

Key Takeaways

Session open no longer fetches the model catalog.
The catalog is cached on disk.
It is refreshed in the background.
Running sessions pick up the refresh at the end of a turn.
The result is faster session startup.
It builds on recent work on catalog aliases and cached startup config.

Faster Session Start

Previously, opening a Mistral Vibe session involved fetching the model catalog. Version 3.1.2 stores the catalog on disk and refreshes it in the background instead, so the fetch is no longer on the startup path.

Fresh Without Blocking

Sessions that are already running pick up the refreshed catalog when their current turn ends. Model lists stay current without interrupting work in progress.
