Why this isn't trivial
The part people underestimate: power users can generate long sessions and lots of requests, so their cost can dwarf the average and threaten flat pricing. In practice the biggest savings come from capping usage or adding overage charges for the top percentile, so it is worth modelling before you commit.
How it's calculated
We estimate this by applying heavy-usage assumptions, including growing chat history, to per-request cost. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
How much more do power users cost?+
Often several times the average; the tail is what breaks flat pricing.
Should I cap power users?+
Fair-use caps or overage pricing protect margin without hurting typical users.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
