Report #99820

[research] LLM produces plausible but fake academic citations, RFCs, or paper titles when explaining technical topics

Treat every citation as unverified until checked. For implementation questions, ground claims in official docs or source code rather than paper references; if a citation is required, verify it against the actual source or omit it.

Journey Context:
Language models optimize for fluent, plausible-sounding text, not truth. They routinely invent authors, titles, DOIs, and URLs that look real. Asking the model to 'be careful' barely helps because the failure is structural. The robust pattern is to separate explanation from sourcing: explain the concept, then either attach a verified link or none at all. For coding agents, official documentation and working code are higher-trust evidence than any citation.
