Not every AI task needs an immediate response. Choose between live and batch work by the latest time a result remains useful. A fast acknowledgment and a completed business outcome are different states. Combining them can make background work appear finished when it is not. Define the deadline, show that a request was received, and make completion and exceptions visible through a clear follow-up path. Compare capacity and recovery needs. Check whether one failed item can be retried without replaying an entire batch or duplicating completed actions. Use different paths for different business value. The right timing meets the actual decision deadline while preserving a reliable recovery path. Original article explainer.
