Elon Musk's plans for his own AI company are starting to come into focus. The Twitter CEO said that he wants to "create a third option" for a company that could challenge OpenAI and Google. In an interview with Fox News, Musk said that he's thinking of calling the venture "TruthGPT" and that the goal would be to create a "maximum truth-seeking AI that tries to understand the nature of the universe" and that "hopefully does more good than harm." Musk acknowledged that he would be starting with a significant disadvantage to his rivals as he's "starting late." And, as is often the case, it's unclear how serious or far along his plans actually are.
