Report #10369

[research] LLM generates plausible but fabricated academic citations and DOIs

Never trust model-generated citations without programmatic verification. Extract the DOI or title and query an external validation API \(e.g., CrossRef, Semantic Scholar, PubMed\) before returning the citation to the user.

Journey Context:
LLMs are trained to predict plausible token sequences, not to query databases. A fake DOI follows the exact structural patterns of a real one \(e.g., 10.xxxx/xxxxx\). Prompting 'do not hallucinate citations' reduces but does not eliminate the error rate because the structural plausibility remains high. The only reliable fix is external grounding via tool use.
