LLM API Price Index: free sample (Tensorust LLC)
Input and output token prices for 452 models across 85 inference providers, one row per model and provider per day.
Headline: Every model OpenRouter lists, with the per-provider price each inference host charges for it: input, output and cache-read price per million tokens, per-request and per-image fees, context length and quantization.
This repository is a free teaser, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has 1,506 rows and is sold by Tensorust LLC: https://tensorust.com/datasets/llm-api-price-index/.
