LLM API Prices is an independent comparison of official LLM API token rates and OpenRouter rates, with source links for each price. It tracks 51 models and includes an in-browser cost calculator (it needs JavaScript), guides, price history and a methodology page.
No API key is needed and the site is not affiliated with the providers. It has no paid plans of its own. The page says some official data is held for review, so check the linked source before relying on a price.
Official LLM API prices and OpenRouter rates are hard to compare for the same workload when channels get mixed. LLM API Prices lists source-linked token rates so monthly cost can be estimated side by side.
