Provenance
Where this claim has been said, linked to its canonical form.
CoT monitoring relies on the assumption that the visible reasoning trace is faithful to the process that produces the answer, and a growing body of work shows that this assumption holds only partially.
Introduction, citing work showing models fail to verbalize cues that determine their outputs.
While thinking models generally exhibit improved faithfulness in their reasoning chains, our findings indicate they still demonstrate measurable levels of unfaithfulness across various reasoning tasks.
