VerifiedBF16 uses 1 sign bit, 8 exponent bits, and 7 mantissa bits, sacrificing precision while retaining the same dynamic range as FP32.68% similarUnverifiedINT4量化将原本由65536个不同值（FP16）表示的权重压缩到仅16个离散级别64% similarUnverifiedThe performance gap between a carefully quantized 4-bit model and the original FP16 model is typically within 1–3 percentage points.64% similarUnverifiedWhen the cumulative sum reaches 1.0, the smallest change representable by FP32 is 1 ULP = 2⁻²³ ≈ 0.00000012.63% similarUnverifiedIn the same test, the bf16 baseline exceeded the self-developed W4 kernel (25.5 tok/s) and bitsandbytes NF4 (25.7 tok/s) at 31.3 tok/s, reaching 29.8% of the theoretical roofline.62% similar
