In October 2025, Musk's xAI venture unveiled Grokipedia, an AI-powered encyclopedia website that directly challenges Wikipedia's longstanding dominance. Harnessing the capabilities of the Grok large language model, Grokipedia asserts that it can deliver a more precise and impartial repository of knowledge. The platform aims to slash the error rate from 3.2% to under 0.8% and to accelerate information updates by a factor of ten.

Musk further declared that Grokipedia's content would be etched onto stable oxide media and launched into the cosmos for eternal preservation. Nevertheless, Grokipedia's debut was marred by controversy. Some of its content bore striking resemblances to Wikipedia, with even verbatim text appearing in places, sparking debates over "AI-driven plagiarism."

Moreover, Grokipedia has been found to harbor notable inaccuracies and to display a biased approach in its entries on political figures, amplifying accusations that it "professes neutrality but leans in practice." Wikipedia co-founder Jimmy Wales expressed his skepticism, stating he has "minimal confidence" in Grokipedia. He argued that current AI language models still fall short in logical reasoning, fact-checking, and grasping the nuances of context.
