Unverified大模型的软性失效（Silent Degradation）表现为输出质量悄然下降而服务技术层面仍正常返回，难以被常规监控告警捕捉72% similarUnverifiedPerformance degradation caused by model drift does not trigger system errors, making traditional monitoring methods (such as error logs and crash rates) completely ineffective against it.70% similarUnverifiedFor problems such as gradual performance degradation or intermittent anomalies that do not manifest as a clear failure of a single operation, Dllog's fail-then-replay model may miss important clues.69% similarUnverifiedData drift and concept drift can cause model performance degradation, but may show no anomalies in service-layer health metrics (latency, throughput, error rate), requiring active detection through statistical methods such as KL divergence, PSI, and KS tests.68% similarUnverifiedIn the context of continuous delivery, a regression specifically refers to a change introduced by a new version that causes a system capability to deteriorate, which may manifest as increased latency, higher error rates, reduced throughput, or feature failures.67% similar
