Definition
The generation of statistically plausible but factually unsupported output by an LLM; while mitigating it via RAG improves accuracy, it introduces trade-offs in system latency and the risk of 'refusal to answer' if retrieval fails.
Distinguishes 'filling in the blanks' with false logic from simple retrieval failures or software bugs.
