Wikipedia Bans AI-Generated Content Amid Accuracy Concerns
The policy update states that text generated by large language models (LLMs) often fails to meet Wikipedia’s core standards.
Wikipedia has introduced new guidelines prohibiting contributors from using artificial intelligence tools to create or rewrite content on its platform, reflecting growing concerns over accuracy and reliability.
The policy update states that text generated by large language models (LLMs) often fails to meet Wikipedia’s core standards, particularly around verifiability and reliable sourcing. “For this reason, the use of LLMs to generate or rewrite article content is prohibited, save for the exceptions given below,” the platform said.
Editors are still allowed to use AI tools in limited ways, including correcting typos, formatting articles and translating content between languages. However, "Caution is required, because LLMs can go beyond what you ask of them and change the meaning of the text such that it is not supported by the sources cited," the organisation warned.
The move highlights broader challenges posed by generative AI, including risks of hallucinations and plagiarism. While the policy does not specify penalties, repeated misuse may be treated as “disruptive editing,” potentially leading to temporary suspensions or permanent bans.
Enforcing the rules may prove difficult. Wikipedia cautioned editors against relying solely on writing style to identify AI-generated content, noting that “Some editors may have similar writing styles to LLMs.” Instead, moderators are encouraged to assess compliance with content policies and review contributors’ editing histories.
The update comes as the Wikimedia Foundation continues to address the impact of AI on its ecosystem. The foundation has previously urged AI companies to use its paid API rather than scrape content, with firms such as Microsoft, Google and Amazon Web Services (AWS) agreeing to do so.
The policy also arrives amid declining traffic, as users increasingly turn to AI chatbots for direct answers instead of visiting the site.
Last year, Wikipedia outlined how AI developers should responsibly use the online encyclopedia’s content—highlighting growing concerns around attribution, sustainability, and a noticeable dip in human readership.
