[Read the method](https://undominated.ai/methodology/) and [correction policy](https://undominated.ai/corrections/). ## Questions this page answers Are the Google Gemma 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? 6 standard rows, of which 6 have an accepted LMArena general score and 6 have known input and output token rates. 2 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. ## Continue your investigation - [Compare exact models](/compare/) - [Inspect model evidence](/models/) - [Check lifecycle notices](/deprecations/) - [Estimate local capacity](/self-host/)
