New benchmark ReasoningShield improves safety detection for LLM reasoning traces

Researchers have developed ReasoningShield, a new benchmark and model suite designed to improve the safety detection of reasoning traces in Large Reasoning Models (LRMs). Existing moderation tools struggle with Chain-of-Thought (CoT) reasoning, showing a significant drop in performance. ReasoningShield addresses this by providing a dataset of 9.2K annotated CoT pairs and lightweight models that achieve a 91.8% F1 score, outperforming current leading tools like LlamaGuard-4 and GPT-4o.

    ReasoningShield: Safety Detection over Reasoning Traces of Large Reasoning Models

    arXiv:2505.17244v3 Announce Type: replace-cross Abstract: Large Reasoning Models (LRMs) leverage explicit reasoning traces, known as Chain-of-Thought (CoT) reasoning, to decompose complex problems into intermediate steps before deriving final answers. However, these reasoning tra…
