Qwen3.8 27b INT4 AWQ 量化在长上下文时加剧循环行为

Reddit 用户在 r/LocalLLaMA 板块分享了关于 Qwen3.8 27b 模型使用 INT8 量化与 INT4 Activation Aware Quantization (AWQ) 性能对比的发现。用户观察到,在使用 INT4 AWQ 时,尤其是在超过 10 万 token 的长上下文长度下,循环行为显著增加,每项任务的成功率下降。虽然 INT8 也出现了循环,但 INT4 量化加剧了这一问题,表明上下文长度和过度压榨模型是导致这些循环的主要驱动因素。 AI

影响 量化选择对模型稳定性和性能有显著影响,尤其是在大规模应用中,长上下文应用需要仔细考虑。
