[research] Relying on verbalized confidence scores to gate high-stakes autonomous actions

Use logit probabilities \(if accessible via API\) to gauge uncertainty. If logits are unavailable, prompt the model to generate its reasoning first, then explicitly ask if it is unsure. Never rely solely on a 1-10 verbalized confidence rating to prevent hallucinations.

Journey Context:
Verbalized confidence is notoriously poorly calibrated; models often state 'Confidence: 9/10' while confidently hallucinating. Logit probabilities \(the mathematical likelihood of the generated sequence\) correlate much better with factual accuracy. If logits aren't available, forcing the model to verbalize its uncertainty after generation is better than before, but still flawed. Relying on verbalized confidence for autonomous action gates is a common trap.
