FP4 Popularity May Stem From Low Information Density

The author theorizes that the popularity of FP4 / 4-bit quantization stems from the fact that in current LLM training sets, 平均到每个参数的信息量可能还不到 4 bit.
They further pose a question: 如果未来智能的“保真度”继续提高，模型参数中是否需要存储更多 bit—meaning, will quantization requirements shift as model capabilities evolve?
