Controlled LLM Training on Spectral Sphere

arXiv — cs.LGWednesday, January 14, 2026 at 5:00:00 AM
  • A new optimization strategy called the Spectral Sphere Optimizer (SSO) has been introduced to enhance the training of large language models (LLMs) by enforcing strict spectral constraints on weights and updates, addressing limitations found in existing optimizers like Muon.
  • This development is significant as it promises to improve the stability and convergence speed of LLM training, potentially leading to more efficient model performance across various architectures, including Dense 1.7B and MoE 8B-A1B.
  • The introduction of SSO highlights a growing trend in AI optimization, where researchers are increasingly focused on developing robust methods that ensure stability and efficiency, as seen in parallel advancements like AuON and ROOT, which also aim to tackle similar challenges in model training.
