Hello Google AI Studio team,
I believe I may have encountered an issue with AI Studio usage limits, and I would appreciate your help verifying whether this is expected behavior or a bug.
Environment
- Google AI Ultra subscription (active)
- Google AI Studio
- Heavy coding workflow using AI Studio
- Project: MY BRAIN AI
- Google Cloud billing enabled
- Gemini API enabled
What happened
Yesterday I upgraded to Google AI Ultra.
Yesterday’s daily limit was reached, which I expected.
Today the daily limits reset successfully.
I started working again at approximately 14:00.
After only about 4 hours of development, AI Studio stopped working and displayed:
“You’ve reached your limit for the day.”
At the same time, another message appeared:
“Encountered retriable error from model provider: Agent execution terminated due to error.”
Why this seems incorrect
I checked multiple places before opening this topic.
Google Cloud
- Billing is active.
- No quota exhaustion is visible.
Gemini API Rate Limits
For my project:
- RPM usage is not exhausted.
- TPM usage is not exhausted.
- RPD usage is not exhausted.
The rate limit dashboard still shows available capacity.
Google Cloud APIs
No API quota errors are reported.
My question
Could someone please clarify:
- Which specific limit is being reached?
- Is this an AI Studio conversation limit?
- Is this an Agent/Flow execution limit?
- Is this related to Gemini Ultra?
- Could this be a temporary backend issue?
At the moment, the message says I have reached the daily limit, but all visible API quotas appear to have remaining capacity.
If needed, I can also provide:
- screenshots of the error,
- Gemini API Rate Limit pages,
- Google Cloud quota pages,
- project configuration.
Thank you very much for your help.
