Most model pricing pages list per-million-token rates. ModelMeter converts those rates into the number teams actually need: estimated monthly API cost for a realistic request volume and token profile.
Cost is only half of the decision. ModelMeter pairs pricing pages with benchmark and source-status pages so builders can weigh speed, quality, context window, and price together.
View benchmark snapshotEach model page includes last-updated dates, source links, status labels, FAQ sections, and internal links so the site can expand without publishing thin keyword pages.
Open Gemini 3.5 Flash pageEnter expected monthly requests, input tokens per request, and output tokens per request. ModelMeter multiplies those estimates by each model's listed per-million-token prices.
Version one focuses on text input and output token pricing. Source links and status labels show where pricing should be checked before purchase decisions.
Yes for early planning, but final procurement decisions should verify provider pricing, discounts, caching, batch pricing, and regional terms.
