Question 1

Which AI model is cheapest right now?

Accepted Answer

Token Price Index ranks all LLM APIs by blended cost (3:1 input-to-output ratio) in real time. The cheapest usable model with 16K+ context is shown in the top picks section and updated daily from OpenRouter's public pricing API.

Question 2

How do I compare AI model prices?

Accepted Answer

Token Price Index normalizes every model to dollars per million tokens and lets you sort by input price, output price, or blended cost. You can filter by provider, context window length, vision capability, and prompt caching support.

Question 3

What is Token Price Index?

Accepted Answer

Token Price Index is a live LLM API pricing aggregator that pulls 462 models from OpenRouter's public API, normalizes pricing to $/1M tokens, and ranks them cheapest-first. It updates daily and is free to browse.

Question 4

How often does AI model pricing change?

Accepted Answer

AI model prices change frequently — often weekly — and the spread between providers for equivalent capability can exceed 100x. Token Price Index refreshes daily so you always see current pricing before committing API spend.

Question 5

Can I get alerts when a model's price drops?

Accepted Answer

Yes. Token Price Index Pro ($9/mo) sends you an email the moment a model you use drops in price or a cheaper equal-capability model ships, plus a weekly cheapest-per-task digest and CSV/JSON export of the full feed.
