  • AI-written content appears to have stalled this year

More new articles on the Internet are written by artificial intelligence than by humans, according to a study. new research from Graphite. Using data from Common Crawl, Graphite found that the number of newly published web articles generated by AI surpassed 50% last November. This figure has stabilized in recent months, but it is still a huge change in how content is created.

The study used AI detection tools applied to 65,000 English-language URLs from the Common Crawl archive, filtering content with article markup and publication dates between 2020 and 2025. They classified each article as AI-generated or human-written based on whether more than 50% of its content met AI detection criteria. Not that the detector is perfect. The study authors estimated the false-positive and false-negative rates to be approximately 4.2% and 0.6%, respectively.
