商汤开源 SenseNova Loop-9B-Preview,以 9B 参数对标 27B 模型

商汤科技 10 月 30 日宣布开源 SenseNova Loop-9B-Preview。该模型采用 Looped Transformer 架构,将中间层改造为参数共享的循环计算模块,以多轮迭代扩展有效计算深度,官方称 9B 参数可媲美 27B 模型。模型还引入 mHC(Manifold-Constrained Hyper-Connections)机制,消融实验显示 GPQA Diamond 和 TeamBench 分别提升 4.42 分和 13.34 分。在 WorkBuddy Bench、RaccoonPPT Bench 和 AutomationBench 等评测中,该模型超过 Qwen3.5-27B。代码已在 GitHub 和 Hugging Face 开源。
