Noah Goodman announced that Humans& has released Ampersand, its first model built with a substantially different training paradigm.
- Training focuses on rich social simulation over long-term outcomes rather than conventional short-horizon objectives.
- Positioned as a collaborator model designed to help people achieve individual and collective goals.
- The team claims that in multi-month simulations, users collaborating with Ampersand accomplished more than with Fable and other frontier models.
- Available to everyone through the company's API.
