01 Has OpenAI API raised prices?
CostBench is tracking OpenAI API pricing (1 dated snapshot so far). A timeline appears here once at least two snapshots exist.
02 How does CostBench track OpenAI API pricing over time?
CostBench re-reads OpenAI API's official pricing page on a rolling oldest-first schedule and stores a dated snapshot each time. Every timeline entry above traces to one of those snapshots — nothing is estimated. What we do not do is publish a price-trend figure: comparing snapshots across a plan lineup that gets renamed and restructured produces mostly false positives, so we show the dated observations and state their limits instead. See our methodology for the full reasoning.
