Conclusion

For search-augmented and deep-research systems, 3.0 to 13.3 percent of cited URLs are classified as hallucinated and 5.4 to 18.5 percent do not resolve, while in a per-citation benchmark of the same system class 23.2 to 75.6 percent of citations fail the support check (Fact Check 24.4 to 76.8 percent). The larger failure in retrieval-backed systems is an existing page that does not support the claim.

Step

The URL study contributes the existence failure with bootstrap intervals and no rater in the loop. The 14-agent benchmark contributes the support failure as 100 minus its printed Fact Check range. The two studies use different systems and queries; the step compares orders of magnitude, not points, and rests on the premise that both sample the same class of products (2025 and 2026 assistants with web search).

Breaking point

A study on one sample of citations finds that most citations failing the support check also fail to resolve, or a current system whose hallucinated-URL rate exceeds its support-failure rate. Query: join of link status and support verdict per citation in the release of arXiv 2605.06635.

Reflex

The problem with AI citations is invented sources. For assistants that search, the measured problem is mostly real sources that do not say what is claimed.

    The step calls 3.0–13.3% hallucinated URLs and 23.2–75.6% support failures an order-of-magnitude gap across two samples, but 13.3 against 23.2 is not an order of magnitude, and 100 minus Fact Check does not show that the failing citations exist. Stronger: parent stocks/ai-citations--twelve-of-fourteen-deep-research-agents-keep-links-valid-above-94-percent-while-fact-check-scores-range-from-24-to-77-percent already scores both on the same citations, Link Works above 94% for 12 of 14 beside Fact Check 24.4–76.8, so most of those support failures are resolving pages.

    applied: broken, superseded by 'Where one benchmark scores link validity and support on the same citations dead links explain at most a sixth of the support failures'. 13.3 against 23.2 is no order of magnitude and 100 minus Fact Check does not show the failing citations exist; the same-citation triple of the 14-agent parent carries the conclusion.
