SenseTime open-sources 9B looped model, claims 27B-level performance
KEY FACTS
- SenseTime open-sourced the SenseNova Loop-9B-Preview model on October 30.
- The model uses a Looped Transformer architecture that expands effective computational depth through recurrent computation.
- The model keeps the original decoder's first and last 4 layers, replacing the middle layers with parameter-sharing recurrent computation modules.
- SenseTime claims performance at the 9B parameter scale is comparable to 27B-parameter models.
- The model outperforms Qwen3.5-27B on three benchmarks, including WorkBuddy Bench.

PHYSIX OBSERVATION
Small-parameter models catching up to large models through architectural innovation rather than parameter stacking is a route that now has verifiable benchmark results. For the industry, inference costs are expected to fall; but the preview results need third-party reproduction, and the actual inference latency of recurrent computation has not been disclosed, so real-world deployment remains to be seen.
