A safety classifier is a lightweight discriminative model independent of the main model, typically built on encoder architectures such as BERT and RoBERTa or fine-tuned small language models, which scores the risk of input content before the request enters the main model for inference.

Unverified现代安全分类器通常采用多层级架构：基于规则的快速过滤、轻量级机器学习模型、基于大型语言模型的深度语义理解76% similarUnverifiedSafety filters typically run as a separate classifier or rule layer before model output, performing intent assessment on requests and generated content to identify whether they involve patterns such as malicious code, credential theft, or authentication bypass.76% similarUnverifiedA safety probe is a defense mechanism that detects malicious prompts by reading vectors from the model's internal hidden layers, without relying on the model's output.73% similarUnverifiedCodex's auto-review mode introduces a lightweight risk assessor that gives a risk score based on the type of operation; low-scoring operations pass silently, while high-scoring operations require manual confirmation.73% similarUnverifiedContent safety filters are typically based on large-scale pre-trained classification models that map input text to risk categories, with judgments relying on word co-occurrence patterns rather than a deep understanding of conversational intent.70% similar
