Muon Operates Beyond the Edge of Stability
Niko Covic, Baraq Lipshitz, Alexander Padula +1
We study the Muon optimizer using sharpness and provide the first empirical evidence that the Flat Minima Hypothesis also applies to Muon. Further, we derive Muon's implicit precon…

Performance Foundations of Parallel & Distributed Reasoning Language Models
Maciej Besta, Leonard Schmidt, Lara Nonino +7
Reinforcement Learning with Verifiable Rewards (RLVR) and other RL-style post-training paradigms have been used for aligning large language models (LLMs) with reasoning standards.…

Accelerating Sparse Ternary GEMM for Quantized ML on Apple Silicon
Baraq Lipshitz, Alessio Melone, Charalampos Maraziaris +1
Sparse Ternary General Matrix-Matrix Multiplication (GEMM) remains under-optimized in existing libraries for Apple Silicon CPUs. We present a Sparse Ternary GEMM kernel optimized s…
