"This feels like AGI": Epic Games CEO Tim Sweeney thinks Grok 4 might be the first step toward real AI

Epic Games CEO Tim Sweeney thinks Elon Musk’s AI chatbot, Grok 4, is starting to feel like the real deal. In a series of tweets, Sweeney shared that Grok 4 gave him the impression of Artificial General Intelligence, or AGI, a level of AI that can think and reason more like a human.

He said Grok 4 didn’t just connect obvious dots or predict words based on statistics. Instead, it gave thoughtful, deep insights into problems it had never seen before. “It is clearly not just constructing statistically likely connections,” he wrote, “but is drawing fairly deep insights… in ways I haven’t seen elsewhere.”

But Sweeney also pointed out where Grok 4 still needs work. According to him, the AI sometimes pulls in confused ideas from online forums and treats them as facts. It also struggles when it comes to understanding information that’s mixed with visuals, like charts or diagrams.

He suggested that one way to improve AI models like Grok would be to train them using expert-written content rather than relying heavily on user-generated posts from the internet. “There are hundreds of thousands of topics where a professional could write a definitive guide,” he said, “and that could be used to clean up the nonsense.”

Grok 4 is part of Musk’s AI company xAI, and is now available under a steep $300/month “Pro” subscription tier for users of X (formerly Twitter). The subscription includes access to Grok 4's most advanced features, built for users who want a chatbot that can not only answer questions, but also engage with complex ideas.
