Change Summary
Weights & Biases removed one sentence from its Master Service Agreement on June 30, 2026, and updated the document's last-modified date from April 22, 2026 to June 29, 2026. The removed language stated that if Customer and W&B had executed a separate written agreement governing access to W&B Assets, that signed agreement would govern and supersede the master terms. The updated agreement no longer includes this provision, meaning the master service agreement now applies without explicit language allowing a previously executed written agreement to take precedence.
