Google Rate Limits by Tier
What are Google's API rate limits?
Google's entry tier (Free) allows an unpublished number of requests/min and an unpublished number of tokens/min for documented default/model family. Limits scale up through Tier 2 as cumulative spend and account age increase — see the full table below, verified 2026-08-14.
Limits by tier
| Tier | Qualification | Model class | RPM | TPM | RPD | Concurrent |
|---|---|---|---|---|---|---|
| Free | Active project or free trial | documented default/model family | — | — | — | — |
| Tier 1 | Linked billing account | documented default/model family | — | — | — | — |
| Tier 2 | $100 paid and 3 days since first payment | documented default/model family | — | — | — | — |
— means not documented by Google, never a guess.
