A confidence score is a numeric estimate, usually between 0 and 1, of how likely an AI system's output is correct. In customer experience automation it governs a routing decision: above a threshold the agent acts, below it the conversation goes to a human.
A confidence score is not a guarantee of accuracy. A model can be confidently wrong, and a low score does not always mean a wrong answer. So a score is only useful when it is calibrated against real outcomes and paired with a clear audit trail, rather than treated as a green light on its own.
In Aide, the agentic AI platform for customer experience, confidence scores are part of the Action Trace, which surfaces the score alongside the full reasoning trail for every automated action. The Aide point of view is intent-first, not just answer-first: confidence is measured per intent, so you see exactly which intents the system handles cleanly and which still belong with a person.
Thresholds are there to gate automation, not to wave it through, and they are validated against real past conversations before they decide anything live. Seeing the score next to its reasoning also teaches the team where the model is strong and where its judgment is thin.
