Wikipedia bans AI-generated content in its online encyclopedia

Wikipedia has banned the use of LLMs (large language models, the AI systems behind tools like ChatGPT) for generating or rewriting article content, as the site's volunteer editors voted that AI often violates Wikipedia's core principles. Two exceptions allow AI for translations and minor copy edits to editors' own writing, though Wikipedia cautions that LLMs can accidentally change meaning or add unsupported information beyond what was requested.
