/models opens the in-session model picker so you can move between grok-code-fast-1, grok-4-latest, and any other models in your list mid-conversation. Use the up and down arrows to highlight and Tab or Enter to select.

The chosen model applies to the rest of the session and is saved as "model" in the project's .grok/settings.json, so it persists the next time you open that project.
