Survival of the Fitted: Qwen3.6-27B’s Jacobian lens reads and steers Qwen3.8-27B with zero refitting [R]

Recent research demonstrates surprising stability in interpretability lenses across model updates. Specifically, a Jacobian lens fitted to Qwen3.6-27B effectively steered Qwen3.8-27B, a subsequent version, with zero refitting. This study, detailed in a new Hugging Face dataset, reveals that transferred lenses maintain their ability to identify latent entities, even exhibiting improved performance at mid-depth layers. The findings suggest a measurable transferability of these instruments, potentially streamlining monitoring pipelines and reducing the need for constant refitting.
