arXiv:2507. 18043v2 Announce Type: replace-cross Abstract: Inference-time steering methods offer a lightweight alternative to fine-tuning large language models (LLMs) and vision-language models (VLMs) by modifying internal activations at test time without updating model weights.
The paper introduces genesis steering, a method that derives a steering vector from contrastive examples in a model’s own fine‑tuning data, and proposes using membership inference to build proxy datasets when such data are unavailable. Two theoretical results are presented on optimal displacement to the decision boundary and reduced proxy‑estimation bias. Experiments on T"ulu‑3‑8B and Llama‑3.1‑8B‑Instruct show that safety data from T"ulu‑3‑8B’s training mixture produce stronger steering than external datasets, and that membership‑based proxy construction can achieve competitive performance.

TopoSteer introduces a topology-based method for selecting the layer at which to apply activation steering in large language models. Instead of evaluating separability or alignment, it scores layers by the total H_0 persistence of the displacement cloud, measured as the length of its Euclidean minimum spanning tree. Experiments across several models and tasks show that this approach yields more effective steering without needing held-out validation.
The paper introduces Where to Steer (W2S), a framework that adaptively selects which layer of a large language model to intervene on based on the input. It argues that optimal steering layers vary across inputs and demonstrates that W2S outperforms fixed-layer steering methods on several LLMs and alignment tasks, both in‑distribution and out‑of‑distribution. The study highlights input‑dependent layer selection as a complementary design dimension to steering vector extraction.
