Hidden Thoughts Are Not Secret: Reasoning Trace Exposure in LLMs
Researchers show that LLM reasoning traces used for distillation can be reverse-engineered, turning a training asset into a vector for proprietary capability extraction.

arXiv:2606.00642v2 Announce Type: replace-cross Abstract: Reasoning traces have become a valuable form of learning signals for improving and transferring the capabilities of large language models. In particular, detailed traces can help distill reasoning behavior from stronger teacher models into weaker student models. The value of capability transfer has motivated many deployed systems with reasoning models to hide raw internal traces and expose at most summaries and answers to users. As a res
Editorial Analysis
Enterprises sharing or exposing chain-of-thought outputs risk enabling competitors or attackers to replicate proprietary model capabilities.
Restrict external access to detailed reasoning traces from proprietary LLMs and assess API outputs for unintended capability leakage.
