Hallucinated Citations
Bibliographic entries generated by large language models during AI-assisted academic writing that are syntactically well-formed but refer to non-existent sources, including fabricated author combinations, fictitious journal names, and nonexistent page numbers. This phenomenon represents an academic integrity challenge associated with AI-assisted writing.

Hallucinated references are a common error of large models: when external resources are needed, the model generates URLs, library names or APIs that are correctly formatted and seemingly plausible but do not actually exist; in interactive web pages that need to load 3D models, textures or third-party scripts, fake links directly break the rendering pipeline, causing sliders, dates and values to lose their linkage.
In the 3D explanation question on the causes of the seasons, Gemini 4 Argon referenced a URL that does not exist, the 3D scene would not load, the slider could not be dragged, and the date and numbers stayed forever at June 21.
Some conferences and journals have begun requiring authors to submit accessible links to cited sources, or having reviewers specifically check reference lists, in order to address the problem of hallucinated citations.
Last year, ICLR desk-rejected some submissions due to hallucinated citations.
Even when the model is explicitly required to answer only based on retrieved documents, it still fills in gaps using parametric memory and generates seemingly well-formatted citations.
This phenomenon is referred to as hallucinated citations or parametric knowledge leakage.
