## Supported finding

The service documents a 50% discount versus synchronous processing for eligible requests with a 24-hour completion window.

## Limits and transfer

Asynchronous only, model/endpoint eligibility and expiry handling matter. The percentage applies to eligible API charges, not total business cost.

## Use in the session

Mechanism and decision conditions. Retain the qualifications when translating the finding into slide copy. No source establishes Knauf's savings.
