xAI Grok API Price History

CostBench has captured 2 dated snapshots of xAI Grok API's pricing page over the period it has been tracked, and 2 differ from the snapshot before it — listed below with dates. Those differences include plan renames and lineup restructures as well as genuine repricing, so read them as observations rather than as a price-change count.

The most recent snapshot that differs from the one before it is dated 2026-05-23: Highest tier decreased from $30 to $3/month. That is an observed difference between two captures of the pricing page, which is not the same as a confirmed price change.

CostBench re-reads xAI Grok 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.
