UnverifiedStep 5 frequently triggers runtime errors on some complex tasks under Q4 quantization, requiring a higher quantization precision such as Q5 or above for stable output.76% similarUnverifiedQ4_K_M通常是兼顾内存效率与生成质量的最优折衷点，而Q2_K虽压缩率更高但在逻辑推理类任务中质量下降明显75% similarUnverifiedQ4 quantization is sufficient for casual conversation and code completion, but for scenarios involving rigorous analysis, long document processing, or the need to reduce hallucinations, switching to Q6 or Q8 versions is recommended.73% 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%.73% similarVerifiedUsing quantized versions (such as Q4, Q5) can significantly reduce VRAM usage with minimal performance loss.72% similar
