Cost-per-token

What each token of input or output costs you — measured in fractions of a cent. High-volume automated tasks like parsing hundreds of client emails can accumulate costs if the prompt is inefficiently written.

Cost-per-token is the granular billing metric for LLM API consumption, defined as the monetary value assigned to each discrete token processed during the inference lifecycle. Providers typically quote rates per million tokens (MTP). In high-throughput production environments, the cumulative cost is a function of the total token volume; therefore, prompt engineering and output constraint strategies are required to minimize the financial impact of inefficient token utilization.
