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).
Step 5 Preview is a model from StepFun. Its posted API price is $1.00 per 1M input tokens, $0.10 per 1M cached input tokens and $2.70 per 1M output tokens, or $0.234 per 1M tokens at the mix of tokens agents send (87% cache read, 12% input, 1% output), unchanged since yesterday and unchanged over the past week. Since Oct 8, 2026 its price at the mix has ranged from $0.191 to $0.234. It carries 93.1% of StepFun's API tokens and is one of the 2 models in the StepFun token price index, $0.223 per 1M tokens today. Of the 34 models in the token index it is the 12th most expensive. At today's H100 rental price of $3.71 per GPU-hour, its break-even throughput is 724 tokens per second per GPU at its list price (3 input : 1 output). Prices are collected once a day, for each UTC day.
