Hallucination
When a model produces plausible but factually wrong or unsupported content.
#风险#事实性#RAG
In plain language
Hallucinations arise because models generate by probability rather than verification. Common forms include invented citations, wrong numbers and nonexistent people or events. Mitigations include retrieval-augmented generation, requiring sources and human review of key claims.
Example
The model invented a paper title and authors that do not exist.
