What is Weights & Biases?
Weights & Biases is the machine learning platform for developers to build better models faster. Use W&B's lightweight, interoperable tools to quickly track experiments, version and iterate on datasets, evaluate model performance, reproduce models, visualize results and spot regressions, and share findings with colleagues. Set up W&B in 5 minutes, then quickly iterate on your machine learning pipeline with the confidence that your datasets and models are tracked and versioned in a reliable system of record.
Are you a first-time user of W&B?โ
If this is your first time using W&B we suggest you explore the following:
- Experience Weights & Biases in action, run an example introduction project with Google Colab.
- Read through the Quickstart for a quick overview of how and where to add W&B to your code.
- Read How does Weights & Biases work? This section provides an overview of the building blocks of W&B.
- Explore our Integrations guide and our W&B Easy Integration YouTube playlist for information on how to integrate W&B with your preferred machine learning framework.
- View the API Reference guide for technical specifications about the W&B Python Library, CLI, and Weave operations.
