Verified4-bit量化使模型存储空间缩减为FP16的约1/485% similarVerified4-bit quantization in GGUF format can compress model weights from 32-bit floating point to 4-bit integers, reducing model size by approximately 8 times.83% similarPartially VerifiedA standard FP32 model occupies 4 bytes per parameter, while INT4 quantization compresses this to 0.5 bytes, theoretically achieving an 8x memory saving.78% similarVerified4-bit quantization (such as Q4_K_M) can typically compress the memory footprint of a 3B model from approximately 6GB to approximately 2GB, with a precision loss of less than 2–3%.78% similar
