Elon Musk said his artificial-intelligence firm xAI will begin training Grok 5, its next-generation large language model, in September. Musk described the new system as a potential step toward artificial general intelligence and predicted it would outperform existing frontier models. The entrepreneur added that Grok-series AI companions will be deliberately programmed with pro-natal features aimed at encouraging higher human birth rates, calling the technology "the biggest pro-birth innovation in history." Musk earlier argued that advanced AI could "one-shot the human limbic system" yet ultimately boost fertility if designed with that goal in mind. Musk’s remarks follow recent third-party evaluations that placed Grok 4 at the top of ByteDance’s FutureX live forecasting benchmark and credited the model with "superhuman" scores on several biology tests. Those results have bolstered expectations for Grok 5 as xAI prepares for the upcoming training run.
