Hey, this is a known bug in version 3.1.14. The model picker was broken for many users, and it’s already fixed.
Try updating Cursor to the latest version via Help > Check for Updates. After updating, Composer 2 should show up again.
If the update isn’t available yet, a temporary workaround is to roll back to version 3.0.16. The model picker works fine there.
Main thread for this bug: No way to select a model in "New Agent" in 3.1.14
Let me know if the update fixed it.
