As answered by people managing LLM Price Watch and Layercode UseCSV.
LLM Price Watch's answer
Open-weight models are tracked at the original provider's own list price, not whichever reseller is cheapest that day, so the numbers don't jump around. And it's a free JSON API as well as a website, so apps and AI agents can check prices and get a model recommendation directly.
LLM Price Watch's answer
Prices are checked every day and new models are added the day they launch. You can plug in your own token volume and see the real monthly bill, embed the calculator on your own site for free, or get a webhook the moment a price changes instead of finding out from your invoice.
LLM Price Watch's answer
Developers, indie hackers and small teams building on AI APIs who need to know what a model will actually cost before they ship, plus agencies and resellers who have to react quickly when a provider changes its pricing.
LLM Price Watch's answer
I kept ending up with five browser tabs and a calculator every time I compared AI API prices for my own projects, so I built the page I wanted. It's run by one person in Norway, in the evenings next to a full-time job. I'm not a developer, I direct AI to do the building.
LLM Price Watch's answer
Cloudflare Workers, Pages and D1 for the site, API and daily price tracker, with OpenRouter's model data as the source, cross-checked against each provider's own listing.
