How do enterprises implement experiment tracking and reproducibility in ML training?

MLflow (open source, deeply integrated with Databricks) tracks parameters, metrics, and artifacts with a model registry. Weights & Biases (W&B) provides richer experiment visualization, hyperparameter optimization, and team collaboration features. Both integrate with SageMaker, Vertex AI, and Azure ML for cloud-agnostic experiment management.

What distributed training strategies work best for large language model training?

LLM training uses combination strategies: Data Parallel (DDP) for batch distribution, Tensor Parallel for splitting model layers across GPUs, Pipeline Parallel for splitting sequential model stages, and ZeRO (Zero Redundancy Optimizer in DeepSpeed) for optimizer state sharding. Libraries like Megatron-LM, DeepSpeed, and PyTorch FSDP implement these patterns.

How should enterprises select between AutoML and custom model training approaches?

AutoML (SageMaker Autopilot, Vertex AI AutoML, Azure AutoML) is appropriate for tabular data classification/regression where data scientists want baselines quickly without manual feature engineering. Custom training is necessary for: custom architectures, fine-tuning foundation models, computer vision/NLP beyond AutoML scope, and achieving state-of-the-art performance on specialized domains.
