[research] Relying on token logit probabilities to gauge factual confidence

Prompt the model to output an explicit self-assessed confidence score \(e.g., 1-10\) or verbalize its uncertainty before answering, as this is better calibrated than raw logits.

Journey Context:
Developers often assume high softmax probabilities equal high factual certainty. However, LLMs are poorly calibrated out-of-the-box; they are frequently highly confident when wrong. Prompting the model to think step-by-step about its own certainty exploits its linguistic understanding of uncertainty, yielding much better calibration for factuality checks.
