Key point

Weights & Biases is changing its Master Service Agreement (MSA) regarding data usage and ownership.

Details

Weights & Biases (W&B) has announced a new Master Service Agreement (MSA) that takes effect on May 11.

The key change concerns the definition of Customer Data and the expansion of W&B's rights to use that data. Under the new terms, Customer Data is defined to include machine learning models, deep learning research projects, and visualization and analytics reports.

The previous agreement stated that customers retained all rights to their data, but that language has been removed in the new agreement. Instead, W&B is granted the right to use Customer Data for the following purposes:

  • Providing and improving W&B's assets
  • Developing new products
  • Enhancing AI capabilities
