Shortly after the launch of OpenAI’s latest artificial intelligence model, ChatGPT-5, Tesla CEO Elon Musk warned Microsoft chief Satya Nadella that “OpenAI is going to eat Microsoft alive.”
Musk made the comment in reply to Nadella’s post on X, where the Microsoft boss announced that GPT-5 is now available across Microsoft 365 Copilot, GitHub Copilot, Azure AI, and other major platforms.
“OpenAI is going to eat Microsoft alive,” Musk wrote, responding to Nadella’s celebratory message on Thursday.

In his post, the Microsoft chief described GPT-5 as “the most capable model yet from our partners at OpenAI,” and praised the rapid progress made in AI over the past few years.
“The pace of progress is only accelerating, and I can’t wait to see what developers, enterprises, and consumers will do with this latest breakthrough,” Nadella wrote.
Today, GPT-5 launches across our platforms, including Microsoft 365 Copilot, Copilot, GitHub Copilot, and Azure AI Foundry.It’s the most capable model yet from our partners at OpenAI, bringing powerful new advances in reasoning, coding, and chat, all trained on Azure.

Musk’s reply, though brief, carried weight, reflecting his growing criticism of OpenAI, the very company he co-founded in 2015 but later fell out with. Musk has long expressed concern about OpenAI’s close partnership with Microsoft and its direction under CEO Sam Altman.
Nadella, however, did not ignore the remark. In a calm yet pointed response, he replied, “People have been trying for 50 years and that’s the fun of it! Each day you learn something new, and innovate, partner, and compete. Excited for Grok 4 on Azure and looking forward to Grok 5!”

His reply referenced Grok, the AI chatbot developed by Musk’s xAI, which is also building on OpenAI’s breakthroughs but taking a different path.
This exchange took place just as OpenAI unveiled GPT-5 to the public on 7 August. Touted as faster, smarter, and more reliable than its predecessor, GPT-5 is now accessible to all ChatGPT users—free and paid alike. OpenAI says the new model brings major improvements in reasoning, safety, and responsiveness.
Despite their rivalry, both Microsoft and Musk’s xAI are betting big on the future of AI. While Microsoft integrates GPT models into its business and productivity platforms, Musk is focusing on building an “uncensored” and “truth-seeking” AI through Grok.
