Memory-Efficient LLM Pretraining via Minimalist Optimizer Design

Athanasios Glentis, Jiaxiang Li, Andi Han +1

Training large language models (LLMs) relies on adaptive optimizers such as Adam, which introduce extra operations and require significantly more memory to maintain first- and seco…

A Framework for Quantifying How Pre-Training and Context Benefit In-Context Learning

Bingqing Song, Jiaxiang Li, Rong Wang +2

Pre-trained large language models have demonstrated a strong ability to learn from context, known as in-context learning (ICL). Despite a surge of recent applications that leverage…

MuonBP: Faster Muon via Block-Periodic Orthogonalization

Ahmed Khaled, Kaan Ozkara, Tao Yu +2

Gradient orthogonalization is a simple strategy that shows great utility in speeding up gradient descent. The Muon optimizer (Jordan, Jin, et al., 2024) combines gradient orthogona…

A Note on the Convergence of Muon

Jiaxiang Li, Mingyi Hong

In this note, we inspect the convergence of a new optimizer for pretraining LLMs, namely the Muon optimizer. Such an optimizer is closely related to a specialized steepest descent…
