• 4-bit floating point FP4

  2.0

  FP4 is a 4-bit floating point format that represents a significant reduction from traditional 32-bit and 64-bit floating point standards. This compact format enables more efficient storage and computation in resource-constrained environments like edge devices and AI accelerators.

• Gaussian distributed weights for LLMs

  2.0

  This post examines the NF4 4-bit floating point format and higher precision analogs used for quantizing LLM weights. NF4 and FP4 are common 4-bit data types in bitsandbytes, often found in weights downloaded from Hugging Face.
