According to Jinse Finance, xAI co-founder Yuhuai Wu posted on the X platform early this morning, stating: "Seeing the release of GPT-5, I feel extremely proud of xAI. With a smaller team, we are ahead in many aspects. Grok4 is the world's first unified model and has outperformed GPT-5 in benchmarks such as ARC-AGI." He believes that OpenAI is a respectable competitor and still leads in many areas. "But we are moving fast and remain relentless. We will be sharing many new models in the coming weeks!" Shortly after, Musk reposted and commented, "Well done." (Jin10)
