UnverifiedIQ2_XXS以约2.06位的平均比特率对权重编码，相比IQ3_S（约3.44位）或Q4_K_M（约4.83位）压缩率更高但信息损失更大74% similarUnverifiedThe IQ (Importance-Quant) series uses activation statistics to measure the importance of each weight and allocates higher precision to more important weights.73% similarUnverifiedTwo metrics in the published benchmark data for IQ3_S are anomalous, which may cause the average score to be inflated.64% similarUnverifiedQ2_K quantization compresses model weights to an average of approximately 2.5 bits, reducing VRAM usage to roughly one-sixth of the original, but causes significant degradation of model capability, jokingly referred to in the industry as a lobotomy.62% similarUnverifiedInference compute is expected to account for two-thirds of total AI computing power.62% similar
