During Wikimania, the global convention for Wikipedia and related projects, held in Paris in July, several discussions and presentations focused on artificial intelligence (AI), a topic of growing importance for the online encyclopedia. Wikipedia, which relies on a vast community of volunteers to create and maintain its content, has been grappling with the use of generative AI—software that can produce text, such as articles or summaries. In the English version of Wikipedia, the use of generative AI to write articles has been banned since March 2024. In the French version, which contains 2.782 million articles, the use of generative AI had been "strongly discouraged" since June. However, users did not follow this guidance consistently, prompting a stricter policy. In mid-September, the Wikipedia community overwhelmingly approved a proposal to prohibit the use of generative AI (GAI) based on large language models (LLM) for writing articles in the French version. This decision followed concerns that GAI tools often violate Wikipedia's core principles, such as the need for verifiable content. Issues such as plagiarism, false information, fabricated sources, and low-quality content have been linked to the misuse of AI. While GAI may seem to save time for individual users, it has led to a greater burden on the community, which must review and correct the errors introduced by AI-generated content. Community members expressed mixed feelings about the new rules. Some emphasized the importance of user responsibility and warned that the volume of AI-generated content could overwhelm Wikipedia's system for monitoring changes. Others acknowledged that many new users misunderstood the "strongly discouraged" guideline as permission to use AI, rather than a clear prohibition. Despite these concerns, some presentations at Wikimania 2026 highlighted instances where AI was used appropriately, such as for spelling correction or as a tool to assist experienced contributors who understand Wikipedia's rules. The new policy includes exceptions: GAI can be used for basic spelling corrections, and experienced contributors may use it for writing assistance under specific conditions. A second proposal, also adopted by the community, prohibits the use of AI-generated text in discussions with other volunteers. This rule aims to ensure that users engage directly with each other, rather than relying on AI-generated responses that may misrepresent Wikipedia's guidelines. While this approach is seen as necessary to maintain the integrity of discussions, it also encourages new users to learn the platform's rules through direct interaction.
