UnverifiedIQ3_S is a non-uniform 3-bit integer quantization scheme that has greater precision loss compared to standard Q4 quantization but requires less storage space and VRAM.79% similarUnverifiedIQ3_S is one of the solutions in the Importance-aware Quantization series.77% similarUnverifiedIn the name IQ3_S, the number 3 indicates that each weight uses approximately 3 bits of storage on average, and the suffix S represents a finer grouping strategy at the same bit count.75% similarUnverifiedThe benchmark performance of IQ3_S is essentially close to the original BF16 precision.72% similarUnverifiedIQ3_S shows a significant overall performance improvement compared to the earlier IQ3_XXS version.70% similar
