Towards understanding and monitorability of reasoning LLMs
Nature Machine Intelligence, Published online: 19 October 2026; doi:10.1038/s42256-026-01333-6 Frontier LLMs are trained to solve problems in a step-by-step way, generating reasoning text in human-understandable language. However, these reasoning tokens are not accurate explanations of LLMs’ internal computations, raising challenges for monitorability.
