How our lightweight, interoperable tools empower your ML team
Develop better models faster
Use the single, central system of record to save all the relevant metadata for your models automatically, so you can focus on model training. Spend more time in a flow state.
Use live dashboards, with system metrics and terminal logs for each experiment, to understand bottlenecks and debug model training quickly, without hopping between tools.
Quickly understand what architecture and hyperparameter choices work, and focus on training new models. Avoid slowly digging through scattered files of manually-tracked results.
How are the latest experiments doing, compared to previous model versions?
Is this model running out of GPU memory? What are the system bottlenecks?
How does this hyperparameter affect accuracy across different classes?
What do sample predictions look like from this model?
Capture valuable insights centrally
Every time you run a new experiment, W&B captures the changes you made and gives you a place to jot down notes. Quickly compare your latest results with previous baselines.
Automatically track the exact version of the code, hyperparameters, and even the dataset your model trained on. Trace back exactly where your resulting models came from.
Annotate findings inside the central W&B system, so your models can speak for themselves. Use interactive notes, comments, and reports to clearly explain your research.
Where are all the model files stored for this project?
What have we tried already, and what avenues should we explore next for improving this model?
What are the key findings from this research?
Move quickly on big projects, and make handoffs seamless
Train on whatever compute is available - AWS, GCP, Azure, or the GPU box in the office. All results are organized in a central place.
Pick the tools that solve your problems best. With W&B, you're not locked in to an end-to-end platform. We pride ourselves on making our tools play well with other systems.
Spend more time in a flow state, and less time doing tedious tracking. With W&B, you can focus on the hard machine learning problems, and let us take care of tracking all the details to make the models reproducible.
How should new team members get started contributing to this ML project?
When someone leaves the team, how is their research saved and communicated?
How are all our projects doing, across the organization? Are any particular projects roadblocked or stuck? Are certain projects performing better than expected?
Version and track every artifact in your model pipeline
Know where a model comes from end to end, and what is running where.
Reliably capture all changes to the data you're using to train your models.
Save datasets in any system: GCP, AWS, Azure, or even uploaded directly to W&B servers.
Clearly identify what downstream steps in your pipeline were affected by a change in data.
Capture all of your trained models in one central system.
Maintain a clear picture of all the data, preprocessing, and evaluation that was done on each model.
Trace back the lineage of any production model to the exact code and data that it was trained on.
What data was this production model trained on?
How did relabeling a chunk of data affect the accuracy of this model?
This data was corrupted — what downstream models were affected by this issue?
How did changing this preprocessing step affect model accuracy?
