Wikipedia bans use of AI for text except for two use cases: Read the policy update

Wikipedia has officially banned the use of artificial intelligence (AI) for generating or rewriting article content. The new policy, now in effect on the English-language Wikipedia, marks one of the biggest editorial decisions the platform has made in years. According to The Verge, Wikipedia updated its guidelines late last week, and says that AI-written articles violate “several of Wikipedia’s core content policies”.

What is now banned and the two exceptions

Under the new rules, Wikipedia editors are not allowed to use AI tools to generate article content or rewrite existing text. The concern is less about accuracy but more about the subtle ways AI can distort meaning.

The policy itself notes, 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.” In easier words, an AI tool may produce text that reads smoothly and sounds authoritative but shifts what an article is actually saying.

Wikipedia, however, has carved out two specific situations where AI tools are permitted. The first is writing assistance. Editors are allowed to use LLMs to suggest refinements to their own writing like grammar checking or light stylistic polish. The second exception is translation wherein editors can use AI to produce a first draft translation of content from another language, but only if they are sufficiently fluent in both languages to catch errors.

What the update policy says

Text generated by large language models (LLMs) often violates several of Wikipedia's core content policies. For this reason, the use of LLMs to generate or rewrite article content is prohibited, save for the exceptions given below.Editors are permitted to use LLMs to suggest basic copyedits to their own writing, and to incorporate some of them after human review, provided the LLM does not introduce content of its own. 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 use of LLMs to translate articles from another language's Wikipedia into the English Wikipedia must follow the guidance laid out at Wikipedia:LLM-assisted translation.Some editors may have similar writing styles to LLMs. More evidence than just stylistic or linguistic signs is needed to justify sanctions, and it is best to consider the text's compliance with core content policies and recent edits by the editor in question.
