A pricing model's endpoint has normal latency, request rate, and error rate. Over the last four daily windows, the inference profile shows RMSE increasing while input drift metrics remain small. Which conclusion and next step are most defensible?

Choose the Best Answer

Investigate regression quality, model version, data-label alignment, and slices. The endpoint must be scaled up because RMSE is a CPU saturation metric. The model registry alias should be renamed because aliases determine RMSE. The trend can be ignored because small input drift proves regression error cannot increase.
