I've also seemingly hit a rate limit on Gemini Pro 2.5 (on an account not subscribed to Gemini Advanced) yesterday, even though my last query is weeks past.
Possibly there's a capacity shortage (I'd presume it all runs on the same Google hardware in the end), and they are prioritizing paid inference?
I hit this yesterday even though my account is on Tier 2 or 3. In my case, the issue was that I was using an old model name (exp-03-25 or something) in requests. Update to the latest pro-preview-whatever and the rate limit issues should go away.
This sounds unintuitive, but in Google's defense the rate limit errors include a link to docs that explain this.
