📚 arXiv Takes Action Against AI Hallucinations
#

Cited a reference that doesn’t exist? On arXiv, that now costs you a 1-year ban. 🚫

📋 The New Policy
#

arXiv has implemented a formal policy for AI-hallucinated references:

  • 🔴 1-year ban for authors submitting papers with AI-fabricated references
  • 🔍 Active review of suspicious citations before publishing
  • ⚠️ Author responsibility — not the AI model’s

🤔 Why Does It Matter?
#

Hallucinated references are a growing problem in science:

  • LLMs generate citations that sound plausible but don’t exist
  • Some papers cited articles with fake DOIs or invented authors
  • Science is built on verifiable references — a bad citation can spread misinformation

💡 Explanation in a nutshell
#

arXiv, the most important preprint repository in exact sciences, implemented a one-year ban for authors who include AI-hallucinated references in their submissions. The policy responds to the increase in papers using LLMs to draft bibliography sections without verifying each citation. The message is clear: authors are responsible for the accuracy of their work, regardless of what tool they used to write it.
