How does Google Vertex AI Training compare to Amazon SageMaker?

Vertex AI Training provides access to Google's TPU pods (unavailable on SageMaker), tighter BigQuery and Vertex Feature Store integration, and a cleaner unified platform experience. SageMaker has a larger built-in algorithm library, SageMaker Experiments for tracking, and deeper AWS ecosystem integration. For TPU workloads (JAX, TensorFlow), Vertex is uniquely advantaged. For PyTorch-heavy workloads, SageMaker and Vertex are comparable.

What is Modal and why is it considered a training alternative?

Modal is a serverless Python cloud that runs GPU functions with millisecond cold starts and per-second billing, eliminating the need to manage training clusters. You define training code as Python functions decorated with GPU requirements, and Modal provisions and runs them on demand. For teams running frequent short-to-medium training jobs, Modal's zero-infrastructure model and cost efficiency rival managed training services.

When should I use Weights & Biases instead of SageMaker Experiments for experiment tracking?

Choose Weights & Biases when training across multiple compute platforms (local GPUs, CoreWeave, GCP, AWS), when you need richer visualization (gradient histograms, system metrics, media logging), or when your team collaborates on ML experiments across environments. SageMaker Experiments is simpler within the AWS ecosystem but less portable. W&B integrates with SageMaker, Vertex, Azure ML, and any custom training environment.
