Staggering 90% of biomedical papers now show signs of AI help

TL;DR - Nature reports that 90% of biomedical papers published in December and archived in PubMed show signs of AI assistance, far exceeding earlier estimates of large-language-model use. The finding suggests AI-supported writing has become widespread in biomedical publishing.

• The reported 90% figure applies specifically to December publications indexed in PubMed.
• The evidence indicates signs of AI help, not necessarily that AI generated entire papers.
• The estimate is substantially higher than previous assessments of LLM use.
• The limited item content does not specify the detection method, sample size or types of assistance measured.
