Paraphrased finding

Asynchronous batch processing has 50% lower model costs versus synchronous API with a 24-hour processing window. Expired jobs are explicitly possible.

Limits

Not an interactive SLA or guarantee every request succeeds. Eligibility, result reconciliation and failed/expired items require handling.
