Startup humans& introduced Ampersand, billed as the first model built as a collaborator to help people achieve individual and collective goals. According to the team, in multi-month simulations users collaborating with Ampersand accomplished more than with Fable and other frontier models. It's available to everyone via API. Researchers praised the shift beyond single-turn reward optimization toward socially intelligent multi-user agents.
