Memory-Induced Tool-Drift in LLM Agents

Mahavir Dabas, Jihyun Jeong, Ming Jin +1

LLM agents increasingly combine long-term memory for personalization with tool calling for taking actions. We study a failure of this combination: personality-driven preferences st…

Remembering More, Risking More: Longitudinal Safety Risks in Memory-Equipped LLM Agents

Ahmad Al-Tawaha, Shangding Gu, Peizhi Niu +2

Safety evaluations of memory-equipped LLM agents typically measure within-task safety: whether an agent completes a single scenario safely, often under adversarial conditions such…

Just Enough Shifts: Mitigating Over-Refusal in Aligned Language Models with Targeted Representation Fine-Tuning

Mahavir Dabas, Si Chen, Charles Fleming +2

Safety alignment is crucial for large language models (LLMs) to resist malicious instructions but often results in over-refusals, where benign prompts are unnecessarily rejected, i…
