Hallucination

In the context of AI and large language models, the generation of content that is plausible-sounding but not grounded in the input data or factual reality. Hallucinations pose a particular risk in accessibility applications such as captioning, audio description, or alt text generation, where users depend on AI output for accurate information access. Managing hallucination risk through confidence indicators, user verification, and post-processing safeguards is essential when deploying AI in accessibility-critical contexts.
