xAI co-founder challenges OpenAI: We have achieved a leading advantage in multiple areas with a smaller team.

Jin10 Data reported on August 8 that Yuhuai Wu, co-founder of xAI, posted on the X platform early this morning, stating: “Seeing the release of GPT-5, I feel very proud of xAI. With a smaller team, we are ahead in many ways. Grok4 is the world’s first unified model and has beaten GPT-5 in benchmark tests such as ARC-AGI.” He believes that OpenAI is a respectable competitor and still leads in many areas. “But we are moving fast and are relentless. We will be sharing many new models in the coming weeks!” Subsequently, Musk retweeted and said, “Well done.”
