Tiered pricing: when a request's prompt (input, cached tokens included) is over 128K tokens, every token in that request is billed at the long-context rates; exactly 128K is still the base rate. This model publishes no separate cached-input price: cached tokens are billed at the input rate of their group (the "Cached input" row shows that rate).
