Providers outside the index, such as the hyperscalers: each one's lowest on-demand price per GPU-hour as it posts it, not standardized to the benchmark contract; a price posted in euros is converted at the European Central Bank's rate of the day, with the euro price under it (methodology).
Gemini 4 Carbon is a model from Google. Its posted API price is $2.00 per 1M input tokens, $0.10 per 1M cached input tokens and $10.00 per 1M output tokens, or $0.427 per 1M tokens at the mix of tokens agents send (87% cache read, 12% input, 1% output). Its price has not changed since Nov 11, 2026. It carries 28.6% of Google's API tokens and is one of the 4 models in the Google token price index, $0.291 per 1M tokens today. Of the 32 models in the token index it is the 10th most expensive. At today's H100 rental price of $3.74 per GPU-hour, its break-even throughput is 259 tokens per second per GPU at its list price (3 input : 1 output). Prices are collected once a day, for each UTC day.
