BWhat changed
Added weight decay and adjusted parameter-update scales for large-model Muon, implementing ZeRO-style distributed orthogonalization and releasing Moonlight checkpoints with scaling experiments.
Scientific scope
Added weight decay and adjusted parameter-update scales for large-model Muon, implementing ZeRO-style distributed orthogonalization and releasing Moonlight checkpoints with scaling experiments. Extends rather than invents Muon/NewtonSchulz/ZeRO, and differs from KimiK2 MuonClip. Approximately twofold compute efficiency is fitted/reported for studied training regimes, not universal wall-clock superiority or tuning-free performance for every architecture.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
