How it works
LLM token cost in this calculator is input and output tokens times their prices. With 12 M in, 4 M out, 3 price in, 15 price out the result is Estimated inference cost: $96.00.
cost = tin × pin + tout × pout. The formula uses tokens and inference.
Estimated inference cost: $96.00 is not an API bill. Another set of numbers gives Estimated inference cost: $23.00, and a further set gives Estimated inference cost: $440.00. Empty optional fields do not change the result.
API exposure answers a different question. Fairness gap does too. Here 12 M in, 4 M out, 3 price in, 15 price out leave Estimated inference cost: $96.00.
Type 12 M in, 4 M out, 3 price in, 15 price out and click Calculate. Two more ready sets sit under the form: Estimated inference cost: $23.00 and Estimated inference cost: $440.00.
Other numbers on the same labels move the result. The first example gives Estimated inference cost: $96.00.
Formula
cost = tin × pin + tout × pout.
