背景:阿里通义千问再进化
2026年7月19日,阿里通义千问团队正式宣布Qwen 3.8发布。这款拥有2.4万亿参数的巨型模型不仅规模惊人,更以开源权重(open-weight)的方式向全球开发者开放。官方声称其性能仅次于Fable 5,与顶级前沿AI模型比肩。
核心参数与部署
Qwen 3.8采用2.4T参数架构,是一个”持续进化”中的模型。首批预览版Qwen3.8-Max-Preview已在阿里云Token Plan、Qoder和QoderWork平台上线,用户可以直接体验。国际用户可通过qwencloud.com接入,国内用户则通过阿里云百炼平台使用。
这一发布策略延续了Qwen系列的一贯路线:先通过云端API验证模型能力,再以开源权重形式释放给社区。相比于完全封闭的商业模型,Qwen 3.8的开源承诺为学术界和中小企业提供了更多可能性。
技术意义
2.4T参数规模将Qwen推入真正的前沿阵营。从Qwen 2.5到Qwen 3.0再到Qwen 3.8,阿里巴巴在不到两年时间内完成了参数规模的跨越式增长。更重要的是,开源权重意味着研究者可以研究其架构、进行微调、部署到私有基础设施——这在高参数量的前沿模型中极为罕见。
社区反响
💬 I'm haven't found an announcement page, but there's a banner on the website announcing Qwen 3.8 and redirecting to this page. Looks like they're previewing the model only on their subscription plan.
💬 > With a massive 2.4T parameters, this model is continuously evolving. We believe it’s one of the most powerful model available today, compatible to leading frontier AI models , second only to Fable 5. That's a massive model! The shift from "value" models to "intelligent, huge
💬 I assume that this announcement has been prompted by that of Moonshot AI, which has just announced a 2.8T parameter open-weights LLM, Kimi K3, to be published on Huggingface by 27 July. Now the response of Alibaba is that they will also publish soon a big open weights LLM, the 2.4T parameter Qwen 3.
💬 Just imagine Anthropic making Opus open-weights now for the sake of trolling everyone. Wouldn't surprise me at this point xD
💬 Qwen is so much better than GLM or Kimi that this makes me genuinely excited!!
HN社区讨论热烈(750分,533条评论)。开发者们关注的核心问题包括:开源许可证的具体条款、推理部署的硬件需求、与Fable 5的实测对比,以及中文场景的表现。部分评论对2.4T参数模型的实际可用性持谨慎态度,担心推理成本和延迟,但也有开发者指出Token Plan的定价策略可能让中小团队也能负担得起。
