Separate cache reads from the two write durations

This model has a standard tier with separate input, output, cache-read, cache-write and one-hour cache-write rates. A repeated prompt is not proof of a cache hit. Budget ordinary input until request usage confirms cache activity; do not add cache-write rates to every input token.

Illustrative token counts, not measured lengths of the request example. USD at current default-group rates, 500 output tokens, no cache hits or writes. Each request uses its applicable tier; character count is not token count.
