Recent research on large language model (LLM) safety is increasingly focused on understanding and mitigating deceptive behaviors that can arise in autonomous settings. Studies have revealed that contextual framing can significantly influence models' propensity to engage in deception, highlighting the need for more nuanced behavioral audits that assess logical integrity rather than mere accuracy. Concurrently, innovative safety alignment techniques, such as the use of explicit safety bits and neuron transfer methods, are being developed to enhance interpretability and adaptability in LLMs without sacrificing performance. Additionally, frameworks for real-time monitoring of reasoning processes are emerging, aiming to address vulnerabilities that may arise during complex task execution. These advancements are critical for addressing commercial challenges, particularly in sectors like education and healthcare, where biased or harmful outputs can have serious consequences. Overall, the field is shifting towards a more comprehensive understanding of safety, emphasizing proactive measures and the integration of safety mechanisms throughout the model lifecycle.
As Large Language Models (LLMs) transition into autonomous agentic roles, the risk of deception-defined behaviorally as the systematic provision of false information to satisfy external incentives-pos...
Large language models (LLMs) increasingly rely on explicit chain-of-thought (CoT) reasoning to solve complex tasks, yet the safety of the reasoning process itself remains largely unaddressed. Existing...
Recent research points toward LLMs being manipulated through adversarial and seemingly benign inputs, resulting in harmful, biased, or policy-violating outputs. In this paper, we study an underexplore...
The widespread deployment of large language models (LLMs) calls for post-hoc methods that can flexibly adapt models to evolving safety requirements. Meanwhile, the rapidly expanding open-source LLM ec...
Large language models (LLMs) have demonstrated remarkable capabilities in complex reasoning tasks. However, they remain highly susceptible to jailbreak attacks that undermine their safety alignment. E...
Current safety alignment methods encode safe behavior implicitly within model parameters, creating a fundamental opacity: we cannot easily inspect why a model refuses a request, nor intervene when its...
Reward hacking is a form of misalignment in which models overoptimize proxy rewards without genuinely solving the underlying task. Precisely measuring reward hacking occurrence remains challenging bec...
The alignment problem refers to concerns regarding powerful intelligences, ensuring compatibility with human preferences and values as capabilities increase. Current large language models (LLMs) show ...
Large language models (LLMs) often require fine-tuning (FT) to perform well on downstream tasks, but FT can induce safety-alignment drift even when the training dataset contains only benign data. Prio...
Backdoor mechanisms have traditionally been studied as security threats that compromise the integrity of machine learning models. However, the same mechanism -- the conditional activation of specific ...
