Report #77035

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

Never generate a citation from memory; only cite documents explicitly provided in the context window, and append the exact source snippet to verify grounding.

Journey Context:
LLMs are trained to predict plausible token sequences, making them excellent at generating realistic-looking but entirely fake DOIs, arXiv IDs, and URLs. Relying on the model's internal weights for citation facts is a known failure mode. Grounding strictly in retrieved context mitigates this, but requires explicit instruction to avoid the model's prior overriding the context.
