Elon Musk launched an early version of an AI-powered encyclopedia called 'Grokipedia' on Monday, with its website temporarily crashing before coming back online hours later.
The new AI service, named after xAI's large language model Grok, has been promoted by Musk as an improved and less biased version of the popular free and web-based Wikipedia.
The Tesla and SpaceX CEO announced last month that he was working on a Wikipedia rival after a suggestion from David Sacks, a fellow tech mogul who is serving as U.S. President Donald Trump administration's AI and crypto czar.
Musk, who has endorsed Germany's far-right extremist party AfD, has previously lambasted Wikipedia as "woke" and criticized it for citing news outlets such as The New York Times and NPR as sources in many of its articles.
In a post on X, Musk said that the launch was only "Grokipedia version 0.1," but that a later "version 1.0 will be 10X better." However, he argued the current version was better than Wikipedia.
Reports and copies of the site on the web archive, The Way Back Machine, indicate the site was down for a few hours.
The Grokipedia.com page features a search bar on a dark background and says it has logged 885,279 articles, which appear to be in a style reminiscent of Wikipedia.
For comparison, the Wikipedia website said it had over 7 million articles on its English Wikipedia as of Tuesday. Wikipedia's articles are also written and edited by a community of volunteer writers and editors, while Grokipedia appears to be solely generated by AI.
