🔑 增強重點摘要

•NVIDIA leverages TensorRT-LLM and quantization techniques (such as INT4 and FP8) specifically tuned for the Jetson Orin architecture to reduce the memory footprint of Large Language Models (LLMs) and Vision-Language Models (VLMs).
•The optimization strategy utilizes memory-efficient attention mechanisms like PagedAttention, which manages KV cache memory dynamically to prevent fragmentation and allow larger context windows on constrained hardware.
•NVIDIA provides specialized software stacks, including the JetPack SDK and the Jetson Generative AI Lab, which offer pre-optimized containers and model deployment workflows to streamline the transition from cloud-based training to edge inference.
