## Questions this page answers

 Are the Gemini 3 family models interchangeable?

No. These are exact catalogue rows with separate capability, pricing and rating evidence. Compare the checkpoint, serving endpoint, reasoning settings and required input types. A family name does not establish equivalent behaviour.

 How many Google rows are compared here?

15 standard rows, of which 7 have an accepted LMArena general score and 15 have known input and output token rates. 8 related free or batch variants are listed separately.

 What do the prices and frontier counts mean?

Prices below are listed US dollars per million input or output tokens, before request-specific context tiers and other billing dimensions. The frontier count comes from the global balanced view. Neither a family price range nor a benchmark difference proves your task will be cheaper or more successful.

 How current are the official notes?

The linked family research was reviewed 2026-09-22. That date is separate from each accepted catalogue observation and each vendor’s effective date. An official note applies to its named platform, not automatically to every reseller.
