๐Ÿ”‘ Enhanced Key Takeaways

  • โ€ขICLR 2026 received 19,814 submissions with a 26.97% acceptance rate, contributing to the overwhelming volume straining peer review processes.[6]
  • โ€ข21% of ICLR 2026 peer reviews were fully AI-generated, with over half showing some AI involvement, and AI-heavy papers receiving lower average review scores.[1]
  • โ€ขGPTZero identified over 50 hallucinated citations in ICLR 2026 papers under review, many missed by 3-5 peer reviewers despite high ratings.[5]
  • โ€ขNeurIPS 2025 saw 100+ accepted papers with AI-hallucinated citations due to submission volumes exceeding 21,000, prompting ICLR to hire GPTZero for checks.[4]
