Corrupt Plans, Clean Traces: Evading Chain-of-Thought Monitoring with Plan Injection

via Arxiv 👤 Keertana Chidambaram, Andrew Ilyas, Vasilis Syrgkanis 📅 2026-09-14

⚡ Score: 7.9

"Chain-of-thought (CoT) monitoring is a safety strategy where the reasoning of a large language model "actor" is inspected by a "monitor" (often another language model) for signs of unsafe planning, deception, or misalignment. We find that planting harmful but benign-sounding reasoning in the actor's..."
