I am using the latest version of cursor. I cannot switch from allowlist mode to auto-review mode. The button is in grey. How can I solve this？

Hey, Auto-review isn’t a bug, it’s expected behavior. This Run Mode uses a background Cursor-managed model classifier, and the option turns gray if there isn’t any model in your active model set that supports that classifier.

This usually happens when you’re using custom or BYOK models with a custom API key or a base URL override. Those don’t support the classifier, so Auto-review isn’t available.

To enable it:

  • Disable the custom API key or base URL override in your model settings, or pick a built-in Cursor model like Auto or any frontier model running on Cursor inference.
  • After that, the Auto-review option should become selectable.

Allowlist mode will still work either way. Let me know if Auto-review is still gray after switching to a built-in model.

Actually I am using composer 2.5 mostly, still unable to switch to auto-review mode

What matters here isn’t the model you pick in the chat, it’s your overall model settings. Auto-review stays greyed out if you have a custom API key or a base URL override enabled in Settings > Models. In that case, the available model list gets replaced with your custom ones (GLM, DeepSeek, Kimi, etc.), and those don’t support the background classifier that Auto-review needs. Picking Composer 2.5 in the chat doesn’t change that.

Check Settings > Models:

  • Turn off custom API key and base URL override (Custom OpenAI or Anthropic keys).
  • Make sure the built-in Cursor models are available (Auto or any frontier model on Cursor inference).

After that, Auto-review should become selectable. Allowlist mode will keep working either way. Let me know if it’s still grey after you disable the override.
