About

Weights was a family of consumer AI products built around creating and sharing AI-generated content, including voice covers, music tools, and visual generation. Its platforms, Weights, Voyages, and Replay, gave more than five million creators ways to produce AI-assisted songs, images, and videos without specialized skills, and became known in part for high-profile use in professional music production.

The company announced that Weights and its team are joining OpenAI, where the team now works on emerging consumer products. As part of that transition, Weights' products and services have been wound down and are no longer available. During its operation, the platform's scale was significant: Voyages produced more than one new image or video every second, and model cards on Weights were used to train over one million AI models.

Key Features

Replay (music prototyping): A music tool used by professionals, including Charlie Puth, who described it as the correct way to use AI for quickly trying out song ideas.
