GRINQH: Graded Input-based Quantization Hierarchy for Efficient LLM Generation

GRINQH introduces a weight-only quantization framework that optimizes large language model inference by dynamically assigning different precision levels to weight channels based on activation magnitudes. The approach achieves state-of-the-art performance on Llama3 and Qwen3 models at 2-4 bit settings, addressing the GPU memory bandwidth bottleneck that constrains decoding speed in edge-computing environments.
