UnverifiedTraining refers to repeatedly iterating model parameters with large-scale data, an offline, long-cycle task; inference is the forward computation process by which the model responds to each user request after going live, a real-time, highly concurrent online task.78% similarUnverified当前多模态模型训练在不同硬件平台上需要维护多套代码，导致高维护成本77% similarVerifiedThe hardware requirements of large model inference differ fundamentally from those of training: training requires extremely large VRAM, extremely high bandwidth, and strong interconnect, while inference's bottleneck lies more in weight loading and KV Cache storage.76% similarUnverified大模型并行训练需要掌握数据并行、张量并行、流水线并行三种策略的组合调度，并使用NCCL通信库和Megatron-LM、DeepSpeed等框架75% similarUnverifiedTrigger-based retraining (based on performance degradation monitoring and data drift detection) can replace scheduled full retraining, directing computational resources precisely where they are truly needed75% similar
