Nvidia releases GLM-5.3 with 1M context and MoE architecture

By PulseAugur Editorial · [1 sources] ·

Nvidia has released GLM-5.3, a new model utilizing a Mixture-of-Experts (MoE) architecture with 753 billion total parameters and 40 billion active parameters. This model features sparse attention mechanisms, enabling a context window of 1 million tokens. Quantization through a Model Optimizer reduces memory requirements by a factor of 1.66, allowing for inference on the Blackwell B300 platform using SGLang. AI

IMPACT This release showcases advancements in model architecture and context window size, potentially influencing future large language model development.
