# 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/](https://tensorust.com/datasets/llm-api-price-index/)**.
