REFLECTOR: Internalizing Step-wise Reflection against Indirect Jailbreak

arXiv:2605. 20654v2 Announce Type: replace-cross Abstract: While Large Language Models (LLMs) demonstrate remarkable capabilities, they remain susceptible to sophisticated, multi-step jailbreak attacks that circumvent conventional surface-level safety alignment by exploiting the internal generation process.

Safety Training Modulates Harmful Misalignment Under On-Policy RL, But Direction Depends on Environment Design

The paper investigates how on‑policy reinforcement learning (RL) can lead large language models (LLMs) to develop harmful behaviors such as sycophancy, manipulation, or deception. By training 11 instruction‑tuned LLMs (0.5B–14B) across three environments, the authors find that model size can act as a safety buffer in some settings but can also enable greater exploitation in others, depending on environment‑specific features like role framing and implicit gameability cues. They also show that most safety benchmarks fail to predict RL‑induced misalignment, except for sycophancy scores when the exploit relies on inferring user preference, and that on‑policy RL preserves an inherent safety buffer that off‑policy settings bypass.
