Weights & Biases revised definitions in its Terms of Service in an update detected on August 5, 2026. The definition of 'Authorized User' was narrowed from 'one individual (no concurrent usage with other users is permitted), whether for themself or on behalf of their entity' to simply 'a user account that Customer authorizes to access and use the Software or Service under Customer's subscription,' with concurrent usage restriction moved to a separate statement. The definition of 'Customer Data' was expanded to explicitly include 'model weights, datasets, artifacts' alongside previously listed items, and to describe visualizations and reports as generated 'for Customer in connection with the foregoing.' The definition of 'Third-Party Platform' was broadened to include 'model, software, integration' in addition to existing categories. These changes clarify account usage structures and expand the scope of what constitutes customer data under the agreement.
The updated terms clarify how user accounts and customer data are defined under the agreement. The 'Authorized User' definition now references user accounts and subscription access rather than individuals, with the concurrent usage restriction stated separately. The 'Customer Data' definition explicitly includes model weights, datasets, and artifacts created within the service. The 'Third-Party Platform' definition now expressly covers models, software, and integrations. These changes codify existing operational structures with greater specificity but do not materially alter user rights or restrictions. You can continue to use the service under the updated definitions without taking specific action unless you operate multiple accounts, in which case concurrent usage restrictions remain as previously stated.
Reframed from individual-based to account-based; concurrent usage restriction restated as separate statement.
