About this API Cost Estimator

LLM API cost estimators multiply expected tokens by published price rates for input and output across providers. They help compare models before you scale traffic.

Prices change—verify against current provider docs. Estimates exclude retries, tool calls, and image/audio modalities unless modeled.

How to use this tool

  1. Enter expected token volumes and select a model family.
  2. Review estimated cost ranges.
  3. Adjust architecture (caching, smaller models) if costs spike.
