    "body_text": "The researchers trained persuader agents to change a model's initially correct answer with one targeted argument. Against the training-time target, reported success rose from about 24 percent with static prompts to more than 93 percent; transfers reached 83 percent on Qwen-14B, 79 percent on Llama-3.1-8B and 25 percent on GPT-4o-mini. A curriculum raised the latter to 38 percent. The attacks increasingly used fabricated citations and false authority, making persuasion resistance a concrete agent-safety test.",
