Quick answers
Does this calculator only cover OpenAI?
The interactive tool also includes Claude models. This landing focuses on OpenAI search intent and deep-links into the same free calculator.
Will it match my OpenAI invoice?
Not always. It uses published list rates for planning. Discounts, batch tiers, and cache hits change the final bill — use TryTokka for synced spend.
How do I track live OpenAI spend?
Connect a billing/usage key in TryTokka. Scout syncs daily (or Sync now) and emails when you cross a threshold.
