What this offer includes
Gemini Developer API provides free input and output tokens for selected models. Not every model supports the free tier, and there is no universal allowance for all accounts.
How to use it
Create a project and API key in Google AI Studio, then inspect the actual limits for each model in the project quota page. Set up Cloud Billing only when choosing to move to paid usage.
Limits and billing
The published pricing terms state that free-tier content may be used to improve Google products. Projects handling sensitive data should review the data-use terms before choosing the free tier.
