Elon Musk said his next-generation artificial-intelligence system, Grok 5, will enter training next month and could be the first iteration of the technology to reach artificial general intelligence, or AGI. In a post on Thursday, the entrepreneur added that he had “not felt that about anything before,” underscoring his confidence in the forthcoming model. Musk did not give technical specifications, a training-data timeline or a release date, but the remarks mark the clearest indication yet of progress at his xAI venture, which is developing Grok as a conversational rival to OpenAI’s ChatGPT and Alphabet’s Gemini. Achieving AGI—software that can perform a wide range of intellectual tasks at or beyond human level—remains an industry benchmark that major labs have yet to meet.
