Use case
Codex Auto Review prompt caching
prompt caching notes for codex-auto-review: the rate card, a worked volume, and when to send this ID. A sample of 1 million input tokens plus 200 thousand output tokens is about $0.088 on corouter (input $0.040, output $0.048).
Cache-read rate
Cache read for codex-auto-review lists at $0.020 and is $0.0040 on corouter per million tokens. Uncached input is $0.040.
Only the input that actually hits cache is billed at the cache-read rate. This page does not promise your prompt will hit.
Where this ID sits
Codex Auto Review is a distinct review ID, not an alias of Luna, even though the list rate is in the same low band. Send codex-auto-review when the caller asks for that ID.
