Wikipedia Bans LLM-Written Articles, Limits AI to Translation and Proofreading After 5% Content Breach

Summary
By March 2026, Wikipedia had barred contributors from using large language models to write articles, allowing AI only for translation and minor proofreading.
A Princeton study found about 5% of nearly 3,000 new English Wikipedia articles in August 2024 contained substantial AI-generated text, often marked by generic filler, fake sources and prompt residue.
Editors first tried to manage and clean up AI output, but a widely read essay, “Death of Wikipedia,” argued that pervasive machine-written content would drive away human contributors and trap volunteers in endless cleanup.
The clampdown comes as Wikipedia faces broader pressure from AI: the site lost almost a quarter of its readership since 2022, or more than 1.1 billion monthly visits, as users increasingly turn to AI summaries instead.
