传闻称 Qwen 4 将发布，但内部评价不及预期
Qwen 4 据传已上线但口碑不佳，原因可能是 Anthropic 封堵蒸馏后没得学。这对关注中美模型差距和蒸馏路线可持续性的开发者来说是个值得盯着的信号。
X 用户 kimmonismus 发帖称 Qwen-4-max 似乎已上线。据其转述的传闻，Qwen 4 整体表现令人失望，未达到外界期待的水平。
帖子给出了一个可能的原因：Anthropic 采取措施防止其模型被蒸馏，使 Qwen 团队难以从 Claude 系列模型输出中提炼训练信号，拖慢了迭代速度。发帖人称真相很快会揭晓。
该帖同时提出判断：如果传闻属实，说明美国实验室在模型能力上仍明显领先。需要注意这些信息均来自未经证实的传闻，正式发布后的基准成绩才是可靠依据。
Qwen-4-max is live it seems. From what I’ve heard so far (rumors), Qwen 4 is disappointing.
It seems that preventing the distillation of Anthropic’s model is putting a brake on development. We will find out very soon.
If this turns out to be true, however, it shows that US labs remain far ahead.
