CC hits their APIs, And internally I'm sure Anthropic tracks those calls, which is what they seem to be referencing here. What exactly did Anthropic do in this test to have "inefficient use of CC" vs your proposed "efficient use of CC"?

Or do you mean that if an external user replicated this experience they might get billed less than $20k due to CC being sold at lower rates than per-API-call metered billing?
