[research] Generating plausible but non-existent URLs, DOIs, or arXiv IDs when asked to cite sources

Never generate citations from parametric memory. Use a strict retrieval-tool-only approach: search, extract the exact URL/DOI from the tool output, and quote it verbatim. If no tool is available, explicitly state 'No live citation available.'

Journey Context:
LLMs are trained to produce well-formed outputs. When asked for a citation, they generate syntactically valid but factually hallucinated identifiers \(e.g., a fake arXiv ID that follows the YYMM.NNNN format\). This is one of the most dangerous failure modes because it produces highly convincing, actionable-looking fake references that users actually click on.

environment: citation-generation · tags: hallucination citations fabrication · source: swarm · provenance: ALCE Benchmark / Enabling Large Language Models to Generate Text with Citations \(Gao et al., 2023, arXiv:2305.14627\)
