SenseTime open-sources Loop-9B, a looped transformer
SenseTime says the 9B model performs like a 27B model on hard tasks.
SenseTime has released SenseNova Loop-9B-Preview as open source. It is a 9-billion-parameter looped transformer that reuses its layers through parameter-shared loops, plus a technique it calls mHC.
SenseTime says it delivers 27B-class performance and beats Qwen3.5-27B on WorkBuddy, RaccoonPPT and Automation benchmarks. It also reports gains on GPQA Diamond and TeamBench.
The company says it plans to scale the approach to larger models next.
