Human Sand's Ampersand, a collaborator model, is now available via Vercel AI Gateway and free for the next week.
Key claims from the team:
- 744B total parameters with 40B active
- Matches or beats all frontier models (e.g. Fable and Astra) on their multi-user long-horizon evals
- Beats most frontier models on external cooperation and multi-agent coding evals
The model is positioned for collaborative, long-horizon and multi-agent workflows.
