Wikipedia's Operator Tells Courts: AI Training Can Be Fair Use, but Chatbots Repeating Articles Should Need a License

According to The Verge, the Wikimedia Foundation, which runs Wikipedia, has filed a court brief taking neither side in the lawsuits by publishers including The New York Times against OpenAI and Microsoft. It argues for treating AI training and AI output differently, and warns that an oversimplified ruling could cost Wikipedia editors useful AI tools or endanger the open web.

Wikipedia's Operator Tells Courts: AI Training Can Be Fair Use, but Chatbots Repeating Articles Should Need a License

What happened

According to The Verge, the Wikimedia Foundation, the nonprofit behind Wikipedia, filed an amicus brief (an opinion submitted to a court by a party outside the case) on Friday. The brief concerns a set of lawsuits by publishers, including The New York Times, against OpenAI and Microsoft, and it sides with neither party.

According to The Verge, Wikimedia said in the filing that it worries both sides are pushing an overly broad and simplified application of fair use. Fair use is a principle in copyright law that allows others' works to be used without authorization in certain circumstances. Wikimedia fears that if the publishers win outright, copyright holders could "gatekeep" even innovative and transformative uses, meaning uses that turn a work into something new. If the AI companies win outright, it says, that could amount to a green light for companies to ignore licensing terms.

Wikimedia's middle-ground position

According to The Verge, Wikimedia argues that scraping websites (automatically collecting web page data with software) should not be treated as infringement. It also argues that using copyrighted works to pretrain large language models, or LLMs (the AI systems behind services like ChatGPT), should be fair use, even without a license, if they provide "something new and different from the original sources."

But according to The Verge, Wikimedia believes a license should be required when a model pulls copies of content in response to a user's query and delivers them to the user, replacing the reader's engagement with the original. In that case, the AI output merely substitutes for the original and does not transform it enough to count as fair use.

AspectWikimedia's position (per The Verge)
Scraping websitesShould not be treated as infringement
Pretraining without a licenseShould be fair use when it provides something new and different
Pulling and delivering content in response to queriesShould require a license if it replaces readers' engagement with the original
What it means for WikipediaThe original source must be credited, and adapted content must stay under the same Creative Commons license

Why this matters especially to Wikipedia

According to The Verge, Wikimedia said in the filing that its sites have become one of the most critical sources of data for all AI and machine-learning training, but that these systems also divert visitors and undermine the communities that maintain the sites. Wikimedia also argues that services like ChatGPT reproduce text freely licensed under Creative Commons (an open content license, which Wikipedia's text uses) without honoring the license terms.

At the same time, according to The Verge, Wikimedia noted that large language models are also useful to Wikipedia, helping editors fight vandalism, detect copyright violations and the publication of others' personal information (doxxing), and find articles that need improvement.

The parties' positions

According to The Verge, The New York Times argues for a more expansive definition of fair use as it applies to large language models and alleges that OpenAI infringed its copyright by scraping its website to build training datasets. OpenAI and Microsoft both argue that using large language models is fair use; OpenAI has said that regurgitating work "is a rare bug."

According to The Verge, Microsoft said in a September filing that expert analysis found Copilot rarely reproduces full sentences from news content used to ground the model, that is, content the model draws on for its answers. Microsoft said this "hardly undermines the transformative purpose of LLM training."

Wikimedia's statements

According to The Verge, Stephen LaPorte, general counsel of the Wikimedia Foundation, said: "A ruling that does not apply fair use principles carefully could threaten the sustainability of free knowledge, and stifle the development of open source technologies, ultimately impacting access to information for everyone in both cases." Wikimedia CEO Bernadette Meehan said that expanding access to knowledge through AI is a powerful goal, but it must respect the people, contributors and communities that make reliable knowledge possible.

In short, Wikimedia wants courts to treat AI training and AI output separately. The Verge's report mentions only the brief and the parties' claims, and does not say that a court has issued a ruling.

Frequently asked questions

What is an amicus brief?

It is an opinion submitted to a court by a party outside the case. According to The Verge, Wikimedia sided with neither party in these lawsuits and instead set out its view of fair use.

Does Wikimedia support OpenAI or The New York Times?

According to The Verge, neither. It believes both sides oversimplify fair use, and argues for drawing a line between training and output.

Has a court issued a ruling?

The Verge's report mentions only Wikimedia's brief and the parties' claims, and does not say that a court has issued a ruling.

Why is Wikimedia worried?

According to The Verge, Wikimedia says AI systems divert visitors and undermine the communities that maintain its sites, and that some services reproduce Creative Commons-licensed text without honoring the license terms. It also worries that an overly black-and-white ruling could cost editors useful AI tools.
