What happened
Pinterest uses Weights & Biases as a core part of its standardized ML engine, MLEnv, for experiment tracking across the organization and for model management through the W&B Registry. It also uses W&B Artifacts as a checkpoint manager and sanity check for fault tolerance training, and W&B logging for training observability.
