01 Has LangSmith raised prices?
CostBench is tracking LangSmith pricing (1 dated snapshot so far). A timeline appears here once at least two snapshots exist.
02 How does CostBench track LangSmith pricing over time?
CostBench re-reads LangSmith'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.
03 Can I get an alert when LangSmith changes pricing?
