DT-Guard: Intent-Driven Reasoning-Active Training for Reasoning-Free LLM Safety Guardrail

arXiv:2607.06326v1 Announce Type: new Abstract: Large language models deployed in open-world applications require safety guardrails that are both robust to complex risks and efficient enough for low-latency runtime moderation. Existing guardrails face a practical trade-off between lightweight classification-based models, which are efficient but often struggle with concealed intent, ambiguous semantics, and borderline safety decisions, and reasoning-based guards, which improve judgment quality but introduce additional token generation and inference latency. We present DT-Guard, a content safety

Why this matters
Why now

The rapid deployment of large language models into diverse applications necessitates advanced safety mechanisms to handle complex and evolving risks, driving innovation in guardrail technology.

Why it’s important

Improving the robustness and efficiency of LLM safety guardrails is critical for broader AI adoption, mitigating regulatory risks, and preventing misuse, which directly impacts public trust and commercial viability.

What changes

The introduction of intent-driven, reasoning-active training offers a more sophisticated and efficient approach to LLM safety, bridging the gap between accuracy in detecting concealed intent and real-time performance.
