New users get a general-purpose free quota on signup, usable across the full model lineup; a 15-day Mini Plan trial is also available

Third-party sources put the free tier's rate limit at roughly 5 RPM / 10 QPM, with a monthly total of roughly 5 million TPM; the exact figures couldn't be directly verified on the official page. A paid subscription is required once the 15-day Mini Plan trial ends.

⚠️The exact free-quota figure couldn't be directly verified on the official page and comes from third-party articles — check your console for what's actually shown. The rate limit is low and unsuited to production use.
