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Google's entry tier (Free) allows an unpublished number of requests/min and an unpublished number of tokens/min for documented default/model family.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 2026-08-15.
