    A single prefilled token can substantially improve control over AI reasoning traces

    Identifies entropy collapse in early reasoning tokens and shows that prefilling a single token improves control over chain-of-thought traces.

    Language models often duplicate the work of their assigned solvers

    Documents that LLMs asked to translate to programs first solve the task in 85% of traces, a reasoning trace content control failure.
