Why this isn't trivial
The part people underestimate: a session bundles several requests plus resent history, so per-1,000-session cost is higher than a naive per-request estimate. In practice the biggest savings come from shortening sessions and windowing history, so it is worth modelling before you commit.
How it's calculated
We estimate this by costing a full session and multiplying by 1,000 at your model's rates. 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
Why price per session?+
Sessions capture multi-turn cost, which per-request numbers miss.
What inflates session cost?+
Long conversations that resend growing history each turn.
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.
