The premise
A rough confidence number, even imperfect, beats no signal at all when routing humans into the loop.
What AI does well here
Ask for a 0-100 score with a one-line rationale
Route low-confidence answers to humans
What AI cannot do
Trust the absolute number
Replace measured calibration on real data
Understanding "Asking Claude and GPT for calibrated confidence scores" in practice: Prompts are the primary interface to language model capability. Precision in prompt structure directly maps to output quality. Get a self-estimated confidence number you can route on, without pretending it is perfectly calibrated — and knowing how to apply this gives you a concrete advantage.
Apply calibration in your prompting workflow to get better results
Apply uncertainty in your prompting workflow to get better results
Apply self-evaluation in your prompting workflow to get better results
Rewrite one of your best prompts using role + context + task + format
Ask an AI to critique your prompt and suggest improvements
Compare outputs from two models using the same prompt
