VerifiedQuantization below Q4 (such as Q3 or Q2) causes excessive loss of weight information on coding tasks, leading to a sharp decline in output quality.80% similarUnverifiedQAT simultaneously optimizes for low loss and flat curvature around the low-loss point, keeping the quantization error within a controllable range.80% similarVerifiedModern quantization schemes (such as Q4_K_M and Q5_K_M) employ grouped quantization and mixed-precision strategies, typically keeping accuracy degradation within 1–3%.77% similarUnverifiedThe performance drop from 2-bit to 1-bit is far greater than the drop from Q4 to Q2, representing a clear performance cliff.76% similarVerified4-bit quantization techniques (such as GPTQ, AWQ, and the GGUF format) can reduce model VRAM requirements to 1/4 of the original, but come with a certain degree of accuracy loss74% similar
