UnverifiedPerformance drift refers to the phenomenon of gradual degradation in model output quality over time, which may stem from silent updates by the model provider, changes in the distribution of contextual data, and updates to the knowledge base of the RAG system.75% similarUnverifiedCovariate shift and model drift can trigger negative transfer, causing additional data to drag down model performance.75% similarUnverifiedThe cascading fallback mechanism automatically escalates requests to a more powerful model when the smaller model's output confidence falls below a preset threshold or is judged substandard by a quality evaluation model.74% similarUnverifiedMulti-step reasoning means multiple model calls, and under real traffic, token consumption and response latency grow non-linearly.71% similar
