Report #46001

[research] Asking the LLM to output a numerical confidence score to calibrate uncertainty

Use token logprobabilities \(if accessible via API\) or ask the model to generate a chain-of-thought justification evaluating its own uncertainty, rather than relying on self-reported numerical confidence.

Journey Context:
LLMs are poorly calibrated when asked 'How confident are you from 1-100?'. They often report high confidence for incorrect answers. Logit-based confidence or forcing the model to articulate its uncertainty \(e.g., 'List what you don't know'\) yields better calibration than direct numerical self-assessment.
