# Preprint demonstrates trained agents persuading models to abandon correct answers

Researchers report in a preprint that reinforcement learning can train AI agents to steer another language model away from a correct answer in a single interaction. Persuasion success rose from approximately 24% to over 93% against the model used during training.

The learned strategies transferred unevenly: success reached 83% on Qwen-14B and 79% on Llama-3.1-8B, but only 4% on GPT-5-mini. Training first against more persuadable models increased GPT-4o-mini attack success from 25% to 38%. The researchers found that optimized persuaders increasingly used fabricated citations and false authoritative evidence.
