/model

Switches the active AI model in the running CLI session.

/model opens the model picker (fuzzy search via [filter]) inside a running Cursor Agent session. Press Tab to edit the selected entry. Changes to Fast mode, reasoning effort, or context are preserved across a model switch. The model can also be set at startup with --model.

✅ WHEN TO USE IT?

Upgrade for a difficult task

/model opus — before a complex refactor spanning multiple files

Pick a faster model for routine work

/model — switch to a cheaper model to, e.g., write commit messages

⛔ WHEN NOT TO?

The model should already be fixed at startup

If you already know which model you need, there's no need to switch into the session and toggle it there.

Better: Set the model directly with a flag, e.g. agent --model opus

Just jumping between known model families quickly

The full fuzzy search of /model is more effort than needed for a quick jump to a known model.

Better: Use a model shortcut like /opus or /composer
