Gemini API — free tier with Google AI Studio
The Gemini API has a free tier with free input and output tokens on Gemini 3.x Flash and Flash-Lite models, no card needed.
- Anyone with a Google account
- Per-project RPM/TPM/RPD, see AI Studio
- Catch: Free-tier content may be used to improve Google products; paid tier does not. Rate limits are per project, can change and are not guaranteed. Flagship Gemini 4 Argon is paid only. Upgrading to Tier 1 requires linking billing.
Free tokens, no card
