Startup Humansand introduced Ampersand, billed as the first model built for people—a collaborator trained to help individuals and groups achieve their goals ("No one changes the world alone"). According to the company, in multi-month simulations users collaborating with Ampersand accomplished more than with Fable and other frontier models. The model is available to everyone through the company's API, with team members vouching for its quality.
