On Thursday, August 7, Elon Musk issued a bold warning to Microsoft CEO Satya Nadella, claiming that OpenAI is “going to eat Microsoft alive.” The Tesla and SpaceX CEO’s remarks came in response to the launch of OpenAI’s newest AI model, GPT-5. Musk further asserted that his company xAI’s model, Grok 4, outperforms GPT-5.

Earlier that day, Nadella had announced the integration of GPT-5 across several Microsoft platforms, including Microsoft 365 Copilot, GitHub Copilot, Azure AI Foundry, and others. Calling it OpenAI’s “most capable model yet,” he highlighted advancements in reasoning, coding, and conversation, all trained using Microsoft’s Azure cloud.

In response, Musk commented on X (formerly Twitter), “OpenAI is going to eat Microsoft alive,” signaling a fierce rivalry in the AI space.

Nadella Responds to Musk’s Claim

Nadella was quick to respond to Musk’s remark with a diplomatic yet pointed reply:
“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.”

Musk Doubles Down on Grok’s Superiority

Not one to back down, Musk continued to promote Grok 4, sharing user feedback that he claimed demonstrated Grok’s superiority over GPT-5.
“Bottom line, though: Grok 4 Heavy was smarter 2 weeks ago than GPT-5 is now, and G4H is already a lot better. Let that sink in,” he posted.

He also teased the upcoming release of Grok 5, saying it will launch before the end of 2025 and describing it as “crushingly good.”
