Unverified从BF16到FP8，内存占用减半，但数值表示精度大幅下降71% similarUnverifiedAfter INT8 quantization, a model at the 0.9B scale can theoretically reduce its inference memory footprint to below approximately 1GB.68% similarUnverifiedQ4_K_M is the most mainstream balanced quantization choice, with perplexity loss typically below 1%; Q2_K can compress a 70B model to approximately 26GB but with a noticeable quality degradation.68% similarVerifiedINT8 quantization loses approximately 0.5% accuracy while halving VRAM usage; INT4 quantization compresses VRAM to 1/4 of the original with an accuracy loss of approximately 1–3%.65% similarUnverifiedDuring epochs 29 to 50, the variance of the sign-pattern loss is only ±0.40%, whereas the magnitude-based variant reaches as high as ±2.25%65% similar
