SenseNova Loop-9B-Preview (`sensenova/SenseNova-Loop-9B-Preview`): released 2026-10-30 by SenseTime under Apache 2.0. Of 32 distinct decoder layers, layers 4-27 share weights and run twice (56 total layer executions), paired with two-stream mHC (Manifold-Constrained Hyper-Connections) managing two residual streams. Training sequence length tops out at 262,144 tokens. An official ablation shows mHC alone adds +4.42 points on GPQA Diamond and +13.34 on TeamBench. It beats the 3x-larger Qwen3.5-27B on WorkBuddy Bench (66.9 vs 60.5), AutomationBench (13.7 vs 10.2), and RaccoonPPT Bench (70.7 vs 59.1), but trails on Terminal Bench 2.1 and T³-Banking. Open weights only, no official API or pricing.
