A request whose prompt is over 272,000 tokens is billed entirely at the long-context rates, output and cache included. The threshold and both rates are the provider's published pricing.

Reference: OpenRouter's public price, checked . You are billed the AZRouter price from prepaid credits.

Each request's total is rounded to the nearest $0.000002 (halves up), so it can differ from the per-unit math by up to $0.000001. How rounding works
