Names such as GSQ-RCO-IQ2_XS and Q8_K_XL belong to llama.cpp's GGUF quantization formats, where smaller numbers indicate more aggressive weight compression (IQ2 is at roughly the 2-bit level).

VerifiedThe llama.cpp project brought the GGUF quantization format into the mainstream, supporting multiple precision levels ranging from Q2_K to Q8_0.67% similarVerifiedThe IQ series is a quantization scheme in llama.cpp targeting extremely low bit-rate (2–3 bit) scenarios, introducing non-uniform quantization grids based on importance matrices, vector quantization, and finer super-block structures63% similarUnverifiedIQ3 is a non-uniform quantization scheme under the GGUF format, developed by the llama.cpp community; compared to earlier uniform quantization methods such as Q3_K, it better preserves critical weights at the same compression ratio.62% similarUnverifiedQ3_K_XL is a mixed-precision quantization scheme in the GGUF format, where Q3 indicates that the main weights are quantized to 3-bit, K denotes the k-quant algorithm, and XL means that higher bit-width is used in key layers to preserve precision.61% similarUnverified实践中所谓的1-bit GGUF通常采用混合方案：embedding层和lm_head等关键组件保留较高精度，中间transformer层使用极低比特，整体平均比特率可能在1.5-2.0 bit/参数之间60% similar
