OpenAI's latest model, GPT-5.2, has reportedly begun citing Grokipedia, an AI-generated encyclopedia from Elon Musk's xAI, as a source for some of its answers. The development creates an unexpected link between the two major AI competitors and raises concerns about large language models (LLMs) training on AI-generated content, a phenomenon experts warn could lead to "model collapse."
In tests, ChatGPT used Grokipedia to answer queries on more obscure or specific topics, such as Iranian political structures and biographical details of a British historian. While OpenAI's model did not appear to replicate Grokipedia's more controversial or debunked narratives on sensitive subjects, the reliance on a rival's AI-generated content platform has sparked debate. Grokipedia itself has faced criticism for propagating right-wing narratives and misinformation since its launch.
