NVIDIA Accelerates LLM Training with Advanced Optimizers
Sonic Intelligence
NVIDIA enhances large-scale LLM training with advanced optimizers like Muon.
Explain Like I'm Five
"Imagine teaching a super-smart robot (an LLM) to understand and talk better. Instead of just telling it 'good job' or 'bad job' (like simple optimizers), NVIDIA found a cleverer way to give it feedback (like Muon). This new way helps the robot learn much faster and smarter, even when it's super big, by sharing the learning work across many robot brains (GPUs) efficiently."

Impact Assessment
Scaling higher-order optimizers for LLM training is crucial for improving model efficiency and quality. NVIDIA's comprehensive support and enabling technologies address significant computational and memory hurdles, making these advanced methods practical for large-scale deployments.
Key Details
- Muon optimizer used to train open-source models like Kimi K2 and GLM-5.
- NVIDIA GB300 NVL72 system used for performance benchmarks.
- Kimi K2 training with Muon achieved 1,080 TFLOPs/s/GPU (MXFP8) on GB300 NVL72.
- Qwen3 30B-A3B training with Muon achieved 721 TFLOPs/s/GPU (MXFP8) on GB300 NVL72.
- Measurements utilized NVIDIA NeMo Megatron Bridge 26.02 library.
Optimistic Outlook
The successful integration of advanced optimizers like Muon could lead to more efficient and stable training of increasingly complex LLMs, potentially reducing training times and computational costs. This could accelerate the development of next-generation AI models with superior performance and capabilities.
Pessimistic Outlook
The inherent computational complexity and memory demands of higher-order optimizers, even with NVIDIA's optimizations, might still limit their accessibility to organizations with extensive GPU resources. This could further concentrate advanced LLM development among a few well-resourced entities.
