Graceful Degradation
Preserving a bounded core service when capacity or dependencies are impaired by reducing optional quality, features, freshness, or workload instead of failing every request.
Why it matters
AI systems often depend on several slow or fallible components, so an explicit reduced mode can protect essential user outcomes during partial failure.
In practice
Predefine which capabilities may be disabled, keep the reduced mode visible to operators, protect safety checks, test the fallback under dependency failure, and restore full service deliberately. Tell users when correctness, safety, freshness, or a promised contract materially changes.
Common confusion
Graceful degradation is not silently returning a worse answer as if nothing happened. Operators always need visibility; users need disclosure when the reduced mode materially changes the result or service contract.
