Weights & Biases

Track machine learning experiments, visualize metrics, and share results

Weights & Biases helps you build better models faster with a central dashboard for machine learning projects. Use our tools to log hyperparameters and output metrics from your runs, then visualize and compare results and quickly share findings with your colleagues.


  1. Experiment Tracking: Visualize experiments in real time

  2. Integrations: PyTorch, Keras, Hugging Face, and more

  3. Hyperparameter Tuning: Optimize models quickly

  4. Data + Model Versioning: Version datasets and models

  5. Data Visualization: Visualize predictions across model versions

  6. Collaborative Reports: Describe and share findings

  7. Self-Hosting: Private cloud and local hosting of the W&B app
