Wikimedia Foundation bans LLM-generated article writing on Wikipedia (March 2026)
After years of experimenting and warnings about AI-written content — including a 2024 Princeton study finding ~5% of new English Wikipedia articles contained substantial AI content — the Wikimedia Foundation banned writing with large language models for article creation by March 2026, limiting their use to translation and minor proofreading. The move follows community concern that AI-generated text, fake sourcing, and falling editor participation could degrade Wikipedia’s reliability and autonomy amid wider shifts such as Google’s AI Overviews in search.
