LionMuon optimizer offers efficient large-scale model training

Researchers have introduced LionMuon, a novel optimizer designed for efficient large-scale training of machine learning models. This new method alternates between Lion's and Muon's update steps, utilizing a shared momentum buffer to reduce computational cost while maintaining strong directional accuracy. Experiments show LionMuon outperforms existing optimizers like Muon, Lion, Signum, and AdamW across various datasets and model sizes, achieving lower validation loss with less compute. AI

IMPACT LionMuon's efficiency could accelerate the training of large-scale AI models, reducing compute costs and time.

    LionMuon: Alternating Spectral and Sign Descent for Efficient Training

    arXiv:2605.19811v3 Announce Type: replace Abstract: In large-scale optimization, the cheapness and effectiveness of update steps are the most crucial factors for a successful optimizer. Sign-based optimizers like Lion or Signum produce cheap per-step updates, whereas Muon's spect…
