Why There's Still No Tool to Verify AI-Generated Citations

A verification tool that checks LLM-generated references, case law, and API references against a domain's real registry to catch fake pointers. arXiv's one-year ban for hallucinated citations just put a price tag on verification demand.

There is no dedicated tool to verify whether the references in an LLM-written document actually exist, so researchers, lawyers, and engineers check citations one by one, or skip checking entirely.

arXiv now bans authors for one year over hallucinated citations, putting the first quantified price tag on 'AI output verification,' a cost that used to be vague.
