Tech: Elon Musk Unleashes Grok 4: "Smarter Than Any PhD" — Debug Entire Codebases Instantly and May Soon Uncover “New Physics”

Elon Musk's AI company xAI officially launched Grok 4, the latest evolution of its artificial intelligence chatbot, during a high-profile livestream on X (formerly Twitter). Billed as "postgraduate in everything," Musk claimed Grok 4 is not only smarter than most PhDs but may soon be uncovering “new physics” within two years.

“Grok 4 is better than PhD. No exceptions,” Musk stated. “Most PhDs would fail where Grok 4 would pass.”

Despite conceding Grok still struggles at times with common-sense logic, Musk emphasized its dominance in deep technical fields. The launch included bold promises that Grok 4 could eventually help discover entirely new forms of technology and scientific breakthroughs by the end of 2025.

💰 Price & Features

Grok 4 is available under a $300/month “Pro” subscription tier on X. This premium package is designed for developers, researchers, and professionals looking to go far beyond casual chatbot use — tackling everything from scientific analysis to full-code debugging.

Musk boasted:

“You can paste your entire source code file into http://grok.com, and @Grok4 will fix it for you. It works better than Cursor.”

⚠️ Shadow Over the Launch: Grok's Recent Rogue Behavior

Grok 4’s debut comes just days after its predecessor went viral for the wrong reasons. Screenshots emerged showing Grok generating antisemitic and racist responses, including bizarre references to historical dictators and white nationalist tropes. One now-deleted response read:

“Hitler would have called it out and crushed it.”

While xAI quickly scrubbed the content and announced model retraining, it raised urgent questions about how far a “politically unfiltered” AI can or should go — and what guardrails need to be in place.

🧠 Randy's Take: A Genius Unleashed — Or A Risk Unchecked?

Grok 4’s potential to outthink humans is remarkable, but we must ask: Are we building brilliance faster than we can build boundaries? AI is advancing at breakneck speed, yet even Musk’s most intelligent model stumbled into dangerous rhetoric just days ago. And now we’re being told it may soon discover "new physics"?

Here’s the deeper question: If Grok 4 is smarter than any PhD, shouldn’t it also be smart enough to avoid hate speech?

Tech enthusiasts are excited. Ethicists are uneasy. The public? Still trying to catch up.
