Wikipedia just banned AI-generated content, allowing only two interesting exceptions

Wikipedia has banned AI-generated content, with just two strict exceptions, after revealing that AI could suffer from model collapse in the future. 

Wikipedia has recently celebrated its 25th anniversary, having launched on January 15, 2001, and has become the go-to source to settle just about any argument or answer any question.

However, Wikipedia has recently reported an eight percent decline in human visitors to its page, as more people rely on generative chatbots or AI-powered search results. 

But the Wikimedia Foundation has explained that AI is completely reliant on human-documented knowledge resources to survive, and has just brought in new rules banning its editors from using it.

The Wikimedia Foundation has warned of AI model collapse – here’s what that means

These days, millions of people rely on AI chatbots for everything from helping them figure out why their car is making that odd noise to writing a professional-sounding email. 

However, recently, YouTuber Hank Green questioned whether the current AI could ‘totally destroy itself’ due to model collapse. 

And it’s something the Wikimedia Foundation says could happen, as AI relies entirely on information that is already out there. 

Although it might seem like your AI assistant is ‘thinking’ it’s actually just drawing on the mountains of data it has been trained on. 

“Generative AI cannot exist without continually updated human-created knowledge – without it, AI systems will fall into model collapse,” the foundation said in a blog post

The foundation went on to explain that without continually updated human-written content, generative AI systems will fall into model collapse. 

Without new information written by people, AI would have to be trained on other AI content, and studies and experiments have shown that this leads to ‘increasingly inaccurate results’. 

“Through experiments on AI models, the team found that models trained on AI-generated data, also known as synthetic data, initially lost information from the tails, or extremes, of the true distribution of data – what they called ‘early model collapse,’ a report from IBM explained. 

“In later model iterations, the data distribution converged so much that it looked nearly nothing like the original data – which researchers termed ‘late model collapse’.”

Wikipedia has introduced a new rule banning AI-generated content, with two exceptions

This week, Wikipedia announced it was banning AI-generated content from its site.

“Text generated by large language models (LLMs) often violates several of Wikipedia’s core content policies,” the website states. 

“For this reason, the use of LLMs to generate or rewrite article content is prohibited.” 

However, it does allow for two exceptions: 

Firstly, editors are allowed to use it to make ‘basic copyedits’ to their own writing, and to incorporate some of these after a human has reviewed them, 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 policy states.

And secondly, LLMs can be used to create a first draft translation, but the editor is still required to be fluent in both languages so they can spot errors. 

This second rule only applies to the English Wikipedia site when translating text from another language into English.
