The Wikimedia Foundation, the nonprofit organization which hosts and develops Wikipedia, has paused an experiment that showed users AI-generated summaries at the top of articles after an overwhelmingly negative reaction from the Wikipedia editors community.

“Just because Google has rolled out its AI summaries doesn't mean we need to one-up them, I sincerely beg you not to test this, on mobile or anywhere else,” one editor said in response to Wikimedia Foundation’s announcement that it will launch a two-week trial of the summaries on the mobile version of Wikipedia. “This would do immediate and irreversible harm to our readers and to our reputation as a decently trustworthy and serious source. Wikipedia has in some ways become a byword for sober boringness, which is excellent. Let's not insult our readers' intelligence and join the stampede to roll out flashy AI summaries. Which is what these are, although here the word ‘machine-generated’ is used instead.”

Two other editors simply commented, “Yuck.”

For years, Wikipedia has been one of the most valuable repositories of information in the world, and a laudable model for community-based, democratic internet platform governance. Its importance has only grown in the last couple of years during the generative AI boom as it’s one of the only internet platforms that has not been significantly degraded by the flood of AI-generated slop and misinformation. As opposed to Google, which since embracing generative AI has instructed its users to eat glue, Wikipedia’s community has kept its articles relatively high quality. As I recently reported last year, editors are actively working to filter out bad, AI-generated content from Wikipedia.

A page detailing the the AI-generated summaries project, called “Simple Article Summaries,” explains that it was proposed after a discussion at Wikimedia’s 2024 conference, Wikimania, where “Wikimedians discussed ways that AI/machine-generated remixing of the already created content can be used to make Wikipedia more accessible and easier to learn from.” Editors who participated in the discussion thought that these summaries could improve the learning experience on Wikipedia, where some article summaries can be quite dense and filled with technical jargon, but that AI features needed to be cleared labeled as such and that users needed an easy to way to flag issues with “machine-generated/remixed content once it was published or generated automatically.”

In one experiment where summaries were enabled for users who have the Wikipedia browser extension installed, the generated summary showed up at the top of the article, which users had to click to expand and read. That summary was also flagged with a yellow “unverified” label.

Wikimedia announced that it was going to run the generated summaries experiment on June 2, and was immediately met with dozens of replies from editors who said “very bad idea,” “strongest possible oppose,” Absolutely not,” etc.

“Yes, human editors can introduce reliability and NPOV [neutral point-of-view] issues. But as a collective mass, it evens out into a beautiful corpus,” one editor said. “With Simple Article Summaries, you propose giving one singular editor with known reliability and NPOV issues a platform at the very top of any given article, whilst giving zero editorial control to others. It reinforces the idea that Wikipedia cannot be relied on, destroying a decade of policy work. It reinforces the belief that unsourced, charged content can be added, because this platforms it. I don't think I would feel comfortable contributing to an encyclopedia like this. No other community has mastered collaboration to such a wondrous extent, and this would throw that away.”

A day later, Wikimedia announced that it would pause the launch of the experiment, but indicated that it’s still interested in AI-generated summaries.

“The Wikimedia Foundation has been exploring ways to make Wikipedia and other Wikimedia projects more accessible to readers globally,” a Wikimedia Foundation spokesperson told me in an email. “This two-week, opt-in experiment was focused on making complex Wikipedia articles more accessible to people with different reading levels. For the purposes of this experiment, the summaries were generated by an open-weight Aya model by Cohere. It was meant to gauge interest in a feature like this, and to help us think about the right kind of community moderation systems to ensure humans remain central to deciding what information is shown on Wikipedia.”

“It is common to receive a variety of feedback from volunteers, and we incorporate it in our decisions, and sometimes change course,” the Wikimedia Foundation spokesperson added. “We welcome such thoughtful feedback — this is what continues to make Wikipedia a truly collaborative platform of human knowledge.”

“Reading through the comments, it’s clear we could have done a better job introducing this idea and opening up the conversation here on VPT back in March,” a Wikimedia Foundation project manager said. VPT, or “village pump technical,” is where The Wikimedia Foundation and the community discuss technical aspects of the platform. “As internet usage changes over time, we are trying to discover new ways to help new generations learn from Wikipedia to sustain our movement into the future. In consequence, we need to figure out how we can experiment in safe ways that are appropriate for readers and the Wikimedia community. Looking back, we realize the next step with this message should have been to provide more of that context for you all and to make the space for folks to engage further.”

The project manager also said that “Bringing generative AI into the Wikipedia reading experience is a serious set of decisions, with important implications, and we intend to treat it as such, and that “We do not have any plans for bringing a summary feature to the wikis without editor involvement. An editor moderation workflow is required under any circumstances, both for this idea, as well as any future idea around AI summarized or adapted content.”
