What is Gemini API?

The Gemini API (via Google AI Studio) gives developers access to Gemini models including Gemini 2.5 Pro and Flash. It offers a generous free tier, simple REST and Python/JS SDKs, and grounding with Google Search — making it a top choice for prototyping and production.

Our Review

The Gemini API's free tier is unmatched — 60 RPM with Gemini Flash for free makes it the best option for prototyping and low-volume production apps. Grounding with Google Search is a genuine differentiator for apps needing current information. For production scale, Vertex AI offers better SLAs.
