UnverifiedTaking the Q4_0 format as an example, every 32 FP32 weights are packed into one quantization block containing one scale factor and 32 4-bit integers, averaging approximately 4.5 bits per parameter, reducing memory usage to approximately 1/8 of the original.75% similarUnverifiedQ3_K_M compresses each weight to approximately 3 bits, reducing the weight size of a 27B model to approximately 12–13 GB.75% similarVerifiedQuantization technology compresses model weights from FP32/FP16 to low-precision formats such as INT8/INT4, which can reduce model size by 50%–75%.75% similarUnverifiedQuantization techniques such as Product Quantization can compress vectors to 1/4 to 1/32 of their original size.75% similarUnverified原版QW3.6 27B模型文件体积约为54GB，Prismo通过数学压缩技术压缩至不到4GB，压缩比超过13倍，且声称不影响模型性能74% similar
