Report #10568
[research] LLM generates plausible but non-existent academic citations or URLs
Implement strict citation verification: force the LLM to output exact quotes from the source text, and programmatically validate URLs/DOIs before presenting them to the user. Never rely on the LLM to generate the URL from memory.
Journey Context:
LLMs are trained to be helpful and fluent, leading them to synthesize realistic-looking citations \(often mixing real authors with fake titles or plausible DOIs\) rather than admitting ignorance. Prompting alone \('do not hallucinate'\) is insufficient. The only robust fix is system-level validation where the LLM is constrained to only cite from a provided context, and any external link is verified via a deterministic tool.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
