Unable to Upgrade Tier in AI Studio (Tier 2 to Tier 3) Despite Meeting Requirements

Hello! I know there are multiple posts that address the same issue, but I’m having difficulty upgrading my Google AI Studio project from Tier 2 to Tier 3 despite meeting the requirements for the upgrade. My project is over 90 days old and I’ve spent over $1.5k on my project. I would greatly appreciate any asssistance anyone can provide in this manner – the upgrade to tier 3 would greatly accelerate my current workflow.

Is anyone able to provide assistance in my rate limit increase?

Thank you for your time.

Hi @Shivam_Singh2 , thank you for your fast response!

The most relevant error message to my situation would be this message:

You exceeded your current quota, please check your plan and billing details. For more information on this error, head to: https://ai.google.dev/gemini-api/docs/rate-limits. To monitor your current usage, head to: https://ai.dev/usage?tab=rate-limit. 
* Quota exceeded for metric: generativelanguage.googleapis.com/generate_content_paid_tier_2_input_token_count, limit: 3000000, model: gemini-3-flash

However, the true error I’m encountering is being unable to upgrade from Tier 2 to Tier 3. Here’s an image of my projects in AI Studio (with the project numbers censored). While there’s an upgrade option for my Tier 1 project, there is no upgrade option for my Tier 2 project.

This is despite meeting the requirements of spending > $1000 and having an account that’s > 30 days old.

If there’s anything else I can send over to help, please let me know!
