Weights & Biases (wandb) is a Python SDK and platform for tracking, visualizing, and managing machine learning experiments, including metrics logging, hyperparameter sweeps, and dataset/model versioning. It integrates with PyTorch, TensorFlow, Keras, and Jax and supports the full ML lifecycle from experimentation to production.
Use cases
- track machine learning experiment metrics
- run hyperparameter sweeps and tuning
- version datasets and models
- compare training runs across experiments
- monitor LLM app evaluations
- log training curves from pytorch or tensorflow
When to choose
- you need experiment tracking and visualization for ML training
- you want reproducible hyperparameter search across runs
- you need team collaboration and model versioning in an MLOps workflow
When to avoid
- you need a fully self-hosted offline solution without a cloud account
- your project is not machine learning related
