Why a Price Tracker?
LLM prices change constantly — promotional launch rates expire, vendors cut prices overnight, and billing models (cached input, thinking tokens, audio) hide the real cost. This site tracks the official numbers and flags upcoming changes, so you can budget before your bill surprises you.
