The article argues that post-training compression techniques for large language models are fundamentally flawed. It explains that these methods, which attempt to reduce model size by quantizing weights after training, fail because they cannot handle the dynamic activation outliers crucial for model intelligence. These outliers, scaling beyond 10^5, are essential for syntactic rules and zero-shot reasoning. Aggressively quantizing them destroys the model's capabilities, while preserving them distorts the quantization scale. The author advocates for native, hardware-software co-designed low-bit architectures, such as 1.58-bit ternary networks (BitNet b1.58) and 1.25-bit architectures (Sherry), as a more effective approach to overcome the memory wall bottleneck and achieve efficient inference.
