Elon Musk on Tuesday announced xAI is creating Grokipedia to compete against Wikipedia while enabling xAI to better learn about the world and the universe. In one post, Musk invited people to join xAI and "help build Grokipedia," which he described as an "open-source knowledge repository that is vastly better than Wikipedia!" "We are building Grokipedia @xAI," Musk said in another post, adding that it "will be a massive improvement over Wikipedia." Among approved Wikipedia sources are Mother Jones, GLAAD, The New York Times and The Washington Post. Such banned sources can be used for opinions, but they cannot be used as factual sources, Sanger told Carlson.
