Thanks for the report and the screenshot β that's helpful.
We've forwarded this to the product team so they can investigate why Opera AI returned a blank response.
To help us reproduce it, could you let us know your Opera version (Settings β "About Opera"), your device model and Android version, and whether it happens with every question or only certain ones? Any of those details will help the team narrow it down.
Thanks again for helping us improve Opera for Android.
