: Neural network weights typically follow a normal distribution. NF4 concentrates its 16 "bins" where most weights exist (near zero), minimizing rounding errors.
: Recent research (April 2026) has further optimized this by creating Fast NF4 Dequantization Kernels that achieve 2.0–2.2× speedups on NVIDIA GPUs. ⚠️ Alternative Interpretation NF4.rar
: An information-theoretically optimal data type for normally distributed weights. It uses 16 quantization levels based on the quantiles of a standard normal distribution. : Neural network weights typically follow a normal
: To reduce the memory footprint of LLMs (like Llama) enough to fit on a single GPU (e.g., a 24GB RTX 3090) while maintaining full 16-bit performance. NF4.rar
