Limitations and caveats

API vs. apps. These limits and prices describe the Gemini API model. The Gemini app and Google AI plans can apply different limits and are billed through subscriptions, not per token.

Google's model card gives a March 2026 knowledge cutoff and says knowledge in some domains may be limited to January 2025.
