Elon Musk, founder of xAI, described the company's AI encyclopedia "Grokipedia," launched in October, as the "modern Alexandria Library" during an interview with Baron Capital. He promised that the project would be completely open source and planned to etch the knowledge base onto stable oxide media and send it to the moon, Mars, and deeper space to avoid the tragedy of "knowledge disappearing again due to civilization's destruction."

Grokipedia currently includes about 885,000 articles, all generated by the Grok large model and marked with real-time verification times. Users can highlight text and interact with the model, submitting correction suggestions. However, the number of entries is still far less than Wikipedia's seven million plus English entries. Musk said that when the content quality is "good enough," the project will be renamed "Encyclopedia Galactica," paying tribute to the "Foundation" series, and will open up its API and full database for download to the public.

To achieve "permanent preservation," xAI is collaborating with a materials laboratory to etch the encyclopedia data onto heat-resistant oxide wafers. Starting in 2026, they plan to deploy them gradually with SpaceX lunar and Martian cargo missions. At the same time, the open-source version will be kept in Earth orbit, ground data centers, and GitHub repositories, achieving "multi-planet backup." Industry experts believe this strategy not only accumulates high-quality training data for xAI but also attempts to occupy a cultural high ground in the narrative of "AI + space."
