Request Tier 2 upgrade - stuck in rate limit loop on gemini-3-pro-image-preview

Hi everyone,

I’m currently on Tier 1 and trying to upgrade to Tier 2,
but I’m stuck in a circular problem:

  • I’m using gemini-3-pro-image-preview (Nano Banana Pro)
    for an image generation app
  • Tier 1 limits me to ~10 images/minute
  • This rate is too low to accumulate the $250 spend
    required for Tier 2
  • So I can never reach Tier 2 naturally

I’ve already:
:white_check_mark: Linked a valid billing account
:white_check_mark: Submitted a quota increase request form
:white_check_mark: Been on Tier 1 for over 30 days

Could any Google staff help manually review my account
for a Tier 2 upgrade? Or is there another way to break
out of this loop?

Thank you!
