How to cite Weights & Biases

If you used W&B and we helped make your research successful, we’d love to hear about it. You can cite us with the information to the right but what we’d like most is to hear from you about your work. Email us at research@wandb.com and we’ll get in touch.

Log everything so you lose nothing

Experiments you can’t reproduce aren’t going to help your next big discovery. With Weights & Biases, you choose what you log and when you log it so you can do less manual admin and a lot more model training.

Integrated with every popular framework and thousands of ML repos

Weights & Biases plays well with others. From PyTorch, Keras, and JAX to niche repos across the ML landscape, chances are, you’ll find us integrated there. Check out our most popular integrations (and how they work) in our docs.

Learn from the experts

Want to learn about MLOps, CI/CD, LLMs, or just how to get started on Weights & Biases? We have free courses to get you started! You can find them all below:

Collaborate with your team in real-time

Weights & Biases is made for collaboration. With each and every experiment logged to a single system, your research team shares access to all dataset and model versions, git commits, and your recent experiments.

The Weights & Biases platform helps you streamline your workflow from end to end

Weave

Traces

Explore and
debug LLMs

Evaluations

Rigorous evaluations of GenAI applications

Track, compare, and visualize your ML models with 5 lines of code

Quickly and easily implement experiment logging by adding just a few lines to your script and start logging results. Our lightweight integration works with any Python script.
