The change in gradient routing may affect training stability, especially when the loss surface is steeper in the early stage of training, and it is recommended to start with small-scale experiments for validation.

UnverifiedDuring large model training, operations such as gradient accumulation, momentum updates, and weight decay are essentially additions, and when weights are large while gradient updates are extremely small, some learning signals may be silently discarded.79% similarVerifiedDuring the post-training phase, an excessively low loss may correspond to overfitting, where the model memorizes the training data and loses generalization ability.78% similarVerifiedThe core process of training a model is to iteratively update parameters in the direction of the loss function's gradient via gradient descent.78% similarUnverified诊断训练瓶颈的核心效率差异来自于是否提前建立了性能基线（baseline），如已知模型健康状态下的MFU则可快速发现偏离76% similarUnverifiedFor teams using MoE architectures, it is recommended to monitor expert load distribution and token coverage early in training; once routing collapse occurs, it is very difficult to fix later by continuing training.75% similar
