Researchers introduce 'future confidence distillation,' a method that trains predictors on pre-solution hidden representations using post-solution correctness probes as teacher signals, enabling reliable confidence estimation before answer generation completes. The paper compares pre-solution Feeling-of-Knowing (FOK) and post-solution Judgement-of-Learning (JOL) confidence estimates across frontier and open-source LLMs, finding post-solution estimates are better calibrated and that linear probes recover richer confidence information than models verbalize. Distilled predictors recover much of the post-solution calibration improvement while remaining sample-efficient and domain-transferable. This has practical implications for confidence-aware systems involving retrieval, tool use, and adaptive computation.
