Limits of Free Tier (API vs AI studio)

I am confused about the limits in the free tier for API vs. AI Studio.

As of today (Jul 21 2025), this page reports the following API limits:

Model RPM TPM RPD
Gemini 2.5 Pro 5 250,000 100
Gemini 2.5 Flash 10 250,000 250
Gemini 2.5 Flash-Lite Preview 06-17 15 250,000 1,000

In AI Studio you can find the limits by hovering over the model, getting:

Model RPM TPM RPD
Gemini 2.5 Pro - - -
Gemini 2.5 Flash 10 ? 500
Gemini 2.5 Flash-Lite Preview 06-17 15 ? 500

Are API usage and AI Studio usages (for the same account) counted completely separately, with distinct limits?

Hi @Luigi_Acerbi,

Welcome to the Forum!

Usage is consistent whether accessed via API or AI Studio. Thank you for flagging this issue. We will file a bug internally.

Thank you!

Thank you. So which one is the correct one?

The information provided in the documentation is accurate.
