Researchers demonstrate that 2-bit quantization of large reasoning models causes instability leading to longer inference traces rather than speedup, but introduce lightweight recovery techniques (FP16 planning and loop rescue) that restore accuracy from 17-65% to 74-87% while maintaining computational efficiency.
GoQuant introduces Orthogonal Residual Projection (ORP), a quantization framework that enables efficient deployment of large language models on edge devices by replacing multiplication operations with bit-shifts. The approach achieves competitive performance at 3-bit precision while reducing calibration time to 15 minutes, addressing fundamental geometric limitations in power-of-two quantization.
Researchers introduce InfoQuant, a training-free method that optimizes activation distributions for low-bit quantization in large language models by using Peak Suppression Orthogonal Transformation. The technique achieves 97% accuracy preservation under W4A4KV4 quantization and reduces performance degradation by 42% compared to previous methods, advancing efficient LLM deployment.
Researchers evaluated HiFloat (HiF8 and HiF4) formats for low-bit inference on Ascend NPUs, finding them superior to integer formats for high-variance data and preventing accuracy collapse in 4-bit regimes. The study demonstrates HiFloat's compatibility with existing quantization frameworks and its potential for efficient large language model inference.
