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.

Channel-Wise Mixed-Precision Quantization for Large Language Models

Researchers introduce Channel-Wise Mixed-Precision Quantization (CMPQ), a novel technique that reduces Large Language Model memory requirements by assigning different precision levels to different weight channels based on activation patterns. The method enables fractional-bit quantization between 2-4 bits while preserving critical information through outlier extraction, addressing deployment constraints on edge devices.

On the Expressive Power of Weight Quantization in Large Language Models

Researchers establish theoretical limits on weight quantization in large language models, identifying 1.58-bit as the minimum precision threshold before expressive collapse occurs. The study demonstrates that model performance degrades polynomially as quantization bits decrease, providing theoretical foundations for optimizing model compression and inference acceleration techniques.
