ULTRA USER reach the usage limit after 10 prompts

Dear Google AI Studio Support Team,

I am writing to inquire about an unexpected usage limitation I have been experiencing when using Gemini 4 Argon in Google AI Studio.

Starting approximately three days ago, I noticed that I consistently reach the usage limit after sending only around ten prompts in each session. This issue occurs repeatedly, even when my prompts consist entirely of ordinary text-based questions and discussions. I have not asked the model to generate code or perform other particularly resource-intensive tasks.

Considering that I am an ultra subscriber,It’s definitely NOT acceptable.Although the usage limits may reset after approximately one hour, I find that I run out of the rates again within just a few minutes of resuming use. This is an extremely restrictive limitation for an Ultra subscriber, and I suspect that there may be a bug or an issue with how usage quotas are being calculated or enforced.

Previously, I was able to use the model without encountering such restrictive limits. I am therefore wondering whether there have been any recent changes to the model’s usage quotas, rate limits, or access policies that might explain this behavior.

I would appreciate it if you could clarify the following:

Have there been any recent changes to the usage limits for Gemini 4 Argon in Google AI Studio?

Is it expected that users may reach the usage limit after approximately ten text-only prompts?

If this behavior is unexpected, could you please advise me on how to resolve it?

I would be grateful for any clarification or assistance you can provide. Thank you for your time and support.

This issue still happens today.I don’t know what happened to my account.

Can anyone help me solve this?
