Startup Humans& has released Ampersand, billed as "the first model built for us" — a collaborator trained through long-horizon simulations of human interaction to weigh the consequences of its actions and help people reach individual and collective goals.
- The company claims that in multi-month simulations, users collaborating with Ampersand accomplished more than with Fable and other frontier models.
- Ampersand is available to everyone through the company's API.
