Report #49687

[research] LLM generates plausible but non-existent academic citations or URLs

Never generate DOIs, arXiv IDs, or URLs from parametric memory. If citing, extract strictly from provided context or use a tool/API to verify existence before outputting.

Journey Context:
LLMs are trained to be helpful and fluent, leading them to interpolate plausible-sounding paper titles and authors. This is notoriously documented in legal and academic domains where fabricated cases/papers have severe consequences. Relying on the model's internal weights for citation metadata yields catastrophic hallucination rates because it optimizes for syntactic plausibility, not factual grounding.
