A new research paper explores the transferability of linear probes, a type of classifier used to detect harmful requests in language models. The study found that probes trained on base models could be effectively reused on distilled or instruction-tuned successor models, even with significant rotation in the model's internal representations. This reusability was observed across different models and evaluation benchmarks, suggesting that linear probes offer a cost-effective method for auditing models without requiring retraining for every new release.
