Sage introduced Sage-A1.5, a 35B Mixture-of-Experts agentic model that builds on its predecessor, A1, to advance long-horizon problem solving through adaptive capability composition. Sage-A1.5 learns not only to solve individual tasks but also to organize work and revise its approach, extending the A1 line from long-horizon execution toward scientific exploration.
In this report, we introduce Sage-A1.5, a 35B Mixture-of-Experts agentic model that builds on A1 to advance long-horizon problem solving through adaptive capability composition. Compared with A1, Sage-A1.5 learns not only to solve individual tasks, but also to organize work and revise its approach d
