UnverifiedUltra-low-bit quantization compresses model weights to 1-2 bits (such as the ternary weights of BitNet b1.58) to reduce storage, memory bandwidth, and matrix multiply-add overhead.76% similarUnverified4-bit quantization (such as bitsandbytes NF4 or GPTQ) weights are usually stored in blocks, with each block carrying a scaling factor and zero point, and these metadata are often stored in FP16 or FP32; embedding layers, output layers, and normalization layers may remain at higher precision, so the actual weight file is typically 5%-15% larger than the theoretical P×b/8 value.76% similarUnverifiedBitNet探索的极端量化（如2-bit或1.58-bit三值量化）在某些场景下也能保持较好性能75% similarUnverifiedDifferent quantization formats (GGUF, AWQ, GPTQ, bitsandbytes) have different metadata overhead and layouts, and peak memory during loading may also differ.71% similar
