/model

Picks the reasoning model, persisting across sessions.

/model belongs to the Configurations category. The choice applies beyond the current session until changed again. Complements the --model startup flag and the agy models subcommand, which lists available models from the Shared Agent Engine (including Gemini 3.1 Pro/3.5 Flash on all plans, and Claude Sonnet/Opus 4.6 plus GPT-OSS-120b on Google AI Ultra only).

✅ WHEN TO USE IT?

Pick a stronger reasoning model for a more demanding task

Open /model and switch to a more capable model

⛔ WHEN NOT TO?

You only want the model set for the next start, not permanently

/model changes the choice persistently across sessions.

Better: Use agy --model <name> at startup
