Researchers have introduced MuonGS, a novel pretraining method for large language models that enhances optimizer performance through relaxed weight-norm control. The method analyzes norm control using the accumulated effective learning rate and demonstrates that MuonGS, by using Gram--Schmidt projection, guarantees sustained norm accumulation and faster convergence. Experiments with models ranging from 135M to 1B parameters showed MuonGS achieving lower validation perplexity and an estimated token-equivalent speedup of up to 15% compared to existing methods like MuonH.
