Mistral Vibe: Session-Only Model and Thinking Pickers

Mistral VibeView original changelog

In the Rust CLI, Mistral Vibe 2.26.1 lets users press s in the /model and /thinking pickers to apply a choice for the current session only, while Enter still saves it to config. Choosing a model now also opens the thinking level picker right away, and both are applied together.

Key Takeaways

  • Pressing s applies a model or thinking level for the current session only, leaving saved config untouched.
  • Enter still saves the choice to the user's config as before.
  • Choosing a model opens the thinking picker immediately, so the two settings are chosen together.
  • Esc cancels both choices, which avoids half-applied changes.
  • A session-only model pick makes the thinking level session-only too, keeping the pair consistent.
  • The change applies to the Rust CLI pickers in Mistral Vibe 2.26.1.

Try a Model Without Changing Your Defaults

Before this release, picking a model or thinking level in the Rust CLI meant changing a saved preference. Mistral Vibe 2.26.1 separates the two intents. In the /model and /thinking pickers, pressing s applies the selection for the current session only. Pressing Enter still saves it to the user's config, as before.

One Flow for Model and Thinking Level

Picking a model now immediately opens the thinking level picker for that model, and the two choices are applied as one action. Esc cancels both, so there is no half-applied state. If the model was chosen for the session only, the thinking level follows suit and is also session-only.

Why It Matters

Developers who switch models for a single hard task no longer have to remember to switch back. The paired flow also removes a common mismatch where a model was changed but its thinking level was left at a value that did not suit it.
