Coin World reported that xAI co-founder Yuhuai Wu stated early this morning on the X platform: "Seeing the release of GPT5, I feel very proud of xAI. With a smaller team, we are ahead in many aspects. Grok4 is the world's first unified model and has defeated GPT5 in benchmark tests such as ARC-AGI." He believes that OpenAI is a respectable competitor and is still ahead in many areas. "But we are moving quickly and not slowing down. We will share many new models in the coming weeks!" Following that, Musk retweeted and said, "Well done."
