Imagen 4 Ultra image generation fails with “user has exceeded quota” despite paid API key

Hello Google AI Studio / Gemini API team,

I am experiencing an issue with Google AI Studio image generation using Imagen 4 Ultra.

I have already linked a paid API key / paid billing setup in order to access Imagen 4 Ultra, but image generation keeps failing with this error:

“Failed to generate image: user has exceeded quota. Please try again later.”

This has been happening for 2 consecutive days, from June 4, 2026 to June 5, 2026.

I paid specifically to use this model, but I am currently unable to generate images at all.

Details:

  • Product: Google AI Studio
  • Model: Imagen 4 Ultra
  • Issue: Image generation fails
  • Error message: “Failed to generate image: user has exceeded quota. Please try again later.”
  • Duration: June 4–5, 2026
  • Billing/API key: Paid API key already linked
  • Screenshot attached

Could you please check whether my paid quota is being applied correctly, whether there is a billing/project synchronization issue, or whether this is a temporary service-side quota bug?

Please also confirm whether failed generations are being counted toward my quota, and whether the quota can be restored or adjusted since I was unable to use the paid model during this period.

Thank you.
