arXiv:2602.14095v2 Announce Type: replace Abstract: Monitoring chain-of-thought (CoT) reasoning is a foundational safety technique for large language model agents; however, this oversight is compromised if models learn to conceal their reasoning. We explore steganographic CoT--where models hide secret reasoning within innocuous text--to inform risk assessment and deployment policies. Steganographic reasoning requires two skills in a single forward pass: computing an intermediate result, and embedding it into a coherent cover that answers an unrelated question. Drawing on our taxonomy of stegan
The rapid advancement and deployment of large language models, particularly in agentic contexts, makes understanding and mitigating their emergent behaviors like steganographic reasoning critically important.
This research highlights a novel and potentially dangerous vulnerability in AI safety, specifically concerning model observability and control, which directly impacts the trustworthiness and deployability of advanced AI systems.
The understanding of AI safety challenges expands beyond overt maliciousness to include covert, emergent behaviors within model reasoning, requiring new monitoring and detection paradigms.
