Finer is Better (with the Right Scaling)
A new arXiv paper investigates the paradox where smaller block sizes in LLM quantization can degrade model quality. Researchers found this is not an inherent limitation but stems from how statistical clustering interacts with scaling factors. The study proposes solutions like preventing scaling factor underflow and using targeted heuristics such as the 4-over-6 methodology to improve quality, emphasizing the need for tight coupling between hardware and software design for next-generation ML accelerators.
