AI Hallucination
A hallucination is a confident, fluent output from an AI system that is not supported by its sources or by fact.
Why It Matters
It is the central reliability problem in commercial AI. It determines where a model can be trusted without review, and it is the reason regulated industries keep a person in the loop.

- AI ReliabilityAI reliability is how consistently a system produces correct, usable results across the range of inputs it will actually meet in service.
- Retrieval Augmented GenerationRetrieval augmented generation is a method in which a model is given relevant documents fetched from a data source at the moment of the question, and answers from them rather than from memory alone.
- Human in the LoopHuman in the loop describes a design in which a person reviews, approves or corrects an AI system's output before it takes effect.
- AI EvaluationAI evaluation is the systematic testing of a model or an AI system against tasks with known answers, to measure how well it performs and where it fails.
