Tesla CEO Elon Musk denied reports from The Wall Street Journal regarding a revenue-sharing agreement between Tesla and the artificial intelligence startup xAI. Musk emphasized that while Tesla has gained valuable insights from discussions with xAI engineers that help accelerate the implementation of unsupervised FSD, there is no need to obtain any permissions from xAI. He pointed out that the xAI models are too large to run on Tesla's inference computers. xAI, founded by Musk, aims to compete with OpenAI and plans to use data from its various companies to train models and improve technology.
