Question About Gemini API Tier 3 Limits and Future Scalability

Gemini API
1

Hello,

I am currently planning a production application using the Gemini API. I am not requesting a rate-limit increase at this time; I only want to understand the limits and scalability before building my application.

I have the following questions:

  1. What is the exact RPM limit for Gemini models on Tier 3?

  2. What is the exact TPM limit for Tier 3?

  3. When RPD is shown as “Unlimited”, does that mean there is no daily request limit?

  4. If my application eventually receives 10,000+ requests at the same time, can Gemini API support this type of workload?

  5. If the current RPM/TPM limits are not sufficient, can I request higher limits later when I move to production?

  6. Is there a maximum RPM/TPM limit that Google can provide for a large-scale production application?

  7. For an application that may eventually have 10,000+ concurrent users, what architecture does Google recommend for handling the requests reliably?

I am only looking for clarification at this stage. I will consider purchasing/upgrading the appropriate API tier later when the application goes into production.

Thank you.
