How do I switch models on the fly without restarting

Use the /model command as a standalone message:
/model sonnet
/model haiku
/model opus
/model gpt
/model gpt-mini
/model gemini
/model gemini-flash
You can list available models with /model, /model list, or /model status.
/model (and /model list) shows a compact, numbered picker. Select by number:
/model 3
You can also force a specific auth profile for the provider (per session):
/model opus@anthropic:default
/model opus@anthropic:work
Tip: /model status shows which agent is active, which auth-profiles.json file is being used, and which auth profile will be tried next. It also shows the configured provider endpoint (baseUrl) and API mode (api) when available.
How do I unpin a profile I set with profile
Re-run /model without the @profile suffix:
/model anthropic/claude-opus-4-5
If you want to return to the default, pick it from /model (or send /model <default provider/model>). Use /model status to confirm which auth profile is active.
