humans& Releases Ampersand, a Model Trained for Group Collaboration

humans& introduced Ampersand, a model it describes as a collaborator trained to help people reach both their individual and their collective goals, and says it is available to everyone through the company's API.

The post's one performance claim is that in multi-month simulations, users collaborating with Ampersand accomplished more than users working with Fable and other frontier models. It gives no numbers and does not say who or what the simulated users were, how long the tasks ran or how accomplishment was judged, and the attached video had no usable transcript. This is humans&'s own claim, and the available evidence cannot show how large the difference was or how it was measured. For background, humans& earlier released Persimmon, a model built to simulate how people talk and interact, which it described as a way to play out hypothetical situations; the Ampersand post does not say whether Persimmon was used in these simulations.
