来源：科技日报 科技日报记者 崔爽 2月25日，继除夕开源Qwen3.5-397B-A17B之后，阿里继续开源千问3.5系列模型。本次开源的三款中等 规模的新模型包括Qwen3.5-35B-A3B、Qwen3.5-122B-A10B、Qwen3.5-27B。基于架构创新和训练突 破，三款模型均超越了更大尺寸的上代旗舰模型。 据了解，千问3.5模型采用混合注意力机制，结合高稀疏的MoE架构创新，并基于更大规模的文本和视 觉混合Token上训练，新模型以更小的总参数和激活参数量，实现了更大的性能提升。 值得注意的是，千问3.5新模型可直接部署于消费级显卡，实现开发者友好。 数据显示，截至目前，阿里已开源千问模型超400个，全球下载量突破10亿次，衍生模型数超20万。同 时，除夕开源的Qwen3.5-397B-A17B 模型已登顶Hugging Face全球榜首。 ...
