Unverified4-bit quantization is typically implemented using frameworks such as GPTQ, AWQ, or GGUF, which minimize precision loss by correcting weight distributions.59% similarUnverifiedCurrent mainstream 4-bit quantization schemes (such as GPTQ and AWQ) universally adopt a group quantization strategy with group size=128.58% similarUnverifiedBitNet b1.58, proposed by Microsoft, restricts each weight to one of three values {-1, 0, 1}, replacing nearly all multiplication operations with addition operations.57% similarUnverifiedIn QSA, a C4 block refers to every 4 adjacent tokens being organized into a single computational unit, with attention selection performed at the block level rather than the token level.57% similarUnverifiedThe 4-bit version of AWQ typically preserves more model capability than naive Round-to-Nearest 4-bit quantization.56% similar
