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.
