Gemini API 429 Error Despite Low Quota Usage on Paid Tier (gemini-2.5-flash)

Sorry to bother u @chunduriv

I am dealing with the very same problem right now, my TPM is not being reset, im on Tier 1, have some quota left on RPD, however TPM is sitting on 1.12m tokens used for the last 20+ minutes.

What should I do about it?

Hello @chunduriv,
I am on Free Tier and have the same problem when gemini-2.5-flash, even it’s my first request, I still receive rate limit error: 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.

{"error":{"message":"{\n \\"error\\": {\n \\"code\\": 429,\n \\"message\\": \\"Resource has been exhausted (e.g. check quota).\\",\n \\"status\\": \\"RESOURCE_EXHAUSTED\\"\n }\n}\n","code":429,"status":"Too Many Requests"}}

Is the only response, I am using Cline AI agent.

AI Studio dash shows the following:

I also have the same problem: error 429 “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.”

And i am not able to see any information about my limits, quota or current usage in ai.dev

Why doesn’t TPM reset every minute as stated in the documentation? Mine has been full for several hours now.

Hi there, I am still facing the same issue. When I call gemini-3-flash-preview, it raised ‘error’: google.genai.errors.ClientError: 429 RESOURCE_EXHAUSTED. {‘error’: {‘code’: 429, ‘message’: ‘Resource has been exhausted (e.g. check quota).’, ‘status’: ‘RESOURCE_EXHAUSTED’}}

I believe my account is already set to be paid and it’s currently a paid Tier 1 account.
(Gemini-2.5-flash works fine, but this model is not desired for my project.)

even I am facing same issue

I am on Tier 3 and am receiving the same issue in my production! My users are receiving errors!

Having this issue with Tier 3 paid account for Gemini 2.5 Flash Lite batch API… less than 10% of the rate limit and it gives me this issue: ERROR: 429 RESOURCE_EXHAUSTED. {‘error’: {‘code’: 429, ‘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/rate-limit. ‘, ‘status’: ‘RESOURCE_EXHAUSTED’, ‘details’: [{’@type’: ‘type.googleapis.com/google.rpc.Help’, ‘links’: [{‘description’: ‘Learn more about Gemini API quotas’, ‘url’: ‘https://ai.google.dev/gemini-api/docs/rate-limits’}]}]}}

NEED HELP URGENTLY! I’m experiencing the same issue with Gemini 2.5 Flash on my client’s Paid Tier 1.

Setup:

  • 5 separate Google Cloud projects, all Tier 1, IDs below:

  • All projects under the same billing account with Paid Tier 1

  • Using gemini-2.5-flash for YouTube video URL analysis

What happens:

  • All 5 API keys return 429 “Resource has been exhausted” within milliseconds of each other
  • Dashboard shows we’re well under limits:
    • RPD: 1.13K / 10K (11% used)
    • TPM: 687K / 1M (69% used)
    • RPM: 14 / 1K (1.4% used)

Evidence from logs:

02:47:20,369 - Key 2 → 429 Resource exhausted
02:47:20,495 - Key 3 → 429 Resource exhausted (126ms later)
02:47:20,614 - Key 4 → 429 Resource exhausted (119ms later)
All 5 keys exhausted within ~250ms

Questions:

  1. What is the actual fix? The Dec 18, 2025 fix mentioned in other threads didn’t resolve this. NEED HELP URGENTLY as this is a PRODUCTION app for a client.
  2. Is there a hidden video/YouTube URL quota not shown in the dashboard?
  3. Do multiple projects under one billing account actually share quota?

Please help! Thank you.

I have the exact same issue and im tier 1. what’s happening?
