Whether a run recorded any work at all worth pricing.
Token input is the TOTAL the provider processed: net-new plus cache reads plus cache writes. A
heavily-cached call can have zero net-new prompt tokens and still incur input cost, so the gate
is on the total rather than net-new alone. Continuous-media runs legitimately record zero tokens
— their work is measured in seconds or images — so units count as usage too.
