From raw interaction to reusable knowledge: Rethinking memory for AI agents
It seems counterintuitive: giving AI agents more memory can make them less effective. As interaction logs accumulate, they grow large, fill with irrelevant content, and become increasingly difficult to use. More memory means that agents must…

Dion2: A new simple method to shrink matrix in Muon
Dion2 reduces the cost of Muon’s orthonormalization step by orthonormalizing only a small, selected submatrix at each iteration. This lightweight approach preserves Muon’s strong performance while significantly improving scalability of optimizer at scale.
