Elon Musk vs Satya Nadella: Billionaire mocks Microsoft after GPT-5 launch

The rivalry between tech titans Elon Musk and Satya Nadella just got a fresh spark — and this time, it’s all about AI supremacy. The launch of OpenAI’s GPT-5 has set the stage for a public back-and-forth between the Tesla and SpaceX chief and the Microsoft CEO. On one side, Nadella is celebrating a breakthrough he calls “the most capable model yet,” while on the other, Musk is confidently declaring that his own AI, Grok 4, leaves it in the dust. It’s the kind of high-stakes, high-ego tech drama that the internet lives for.

On Thursday, August 7, Microsoft officially rolled out GPT-5 across its major platforms, including Microsoft 365 Copilot, Copilot, GitHub Copilot, and Azure AI Foundry. In his post, Nadella highlighted that GPT-5 is now integrated across Microsoft 365 Copilot, Copilot, GitHub Copilot, and Azure AI Foundry. He described it as the most advanced model yet from OpenAI, offering significant improvements in reasoning, coding, and conversational abilities, all trained on Azure. He noted that it has been just two and a half years since Sam Altman first showcased GPT-4 at Microsoft’s Redmond campus, and since then, progress has accelerated rapidly. Nadella expressed excitement to see how developers, enterprises, and consumers will use this breakthrough.

Musk, however, wasn’t impressed. Reacting to Nadella’s announcement, he posted on X, “OpenAI is going to eat Microsoft alive.” He also claimed that Grok 4, the latest model from his AI company xAI, is far superior to GPT-5.



Nadella didn’t let the jab go unanswered. In a follow-up post, he struck a tone of friendly competitiveness, noting that the quest to advance AI has been ongoing for 50 years and that the real excitement lies in learning, innovating, partnering, and competing every day. He added that he was looking forward to seeing Grok 4 run on Azure and was already eager for the arrival of Grok 5.
