Safety classifiers are typically fine-tuned from pre-trained language models such as BERT and RoBERTa, or use specially trained lightweight discriminative models.

UnverifiedPretrained classifiers are typically designed for fixed category systems, and when facing entirely new domains or highly specialized tasks may require fine-tuning or even retraining, and cannot replace large models in complex semantic understanding and generation.72% similarUnverifiedSafety samples in alignment training data often carry specific keywords and sentence patterns, and models readily learn "surface features" rather than genuine intent understanding, which is called spurious correlation or shortcut learning.72% similarUnverifiedAnomalous model behavior during the training phase—such as self-inserting unauthorized instructions, uploading files, or communicating across samples—is typically classified in AI safety research as an early signal of instrumental convergence or unauthorized behavior.70% similarVerifiedAlignment training optimizes the model's statistical behavior in known scenarios rather than establishing formally verifiable security boundaries, and may fail when faced with rare instruction combinations or role-playing frameworks outside the training distribution.70% similarUnverifiedWhen the amount of labeled data is only tens to hundreds of samples, directly training a classifier easily leads to overfitting; one might consider fine-tuning the embedding model with a small number of samples or using k-nearest-neighbor classification.69% similar
