Hey, thanks for the report! This is a prompt engineering issue where internal system instructions are “leaking” into user-visible responses for Gemini 3.0 Pro.

Since Gemini 3.0 Pro only launched yesterday, the team is still working through a number of integration issues. I’ll pass this on to the team.

In the meantime, the model should still function correctly, and the tags are just visual noise in the output.
