- What it is
- Google's price list for the Gemini Developer API. It gives per-token and per-minute rates for the Gemini 3.5 Transcribe and Gemini 3.5 Transcribe Live speech-to-text models, and the token rate Google uses to estimate their cost.
- How much weight it carries
- Official Google page, read on 2026-10-17. Rates change, and the page shows some prices that take effect on a later date, so check it before you budget. The per-minute figures are Google's estimates from its stated token rates, not a metered price for every file.
