Elon Musk Unveils Grok 4: xAI’s Most Advanced AI Yet, Priced at $300/Month

In a high-profile livestream on X (formerly Twitter), Elon Musk and his xAI team pulled back the curtain on Grok 4 — the latest evolution of their artificial intelligence chatbot. Billed as the most capable version yet, Grok 4 is being positioned not just as a digital assistant, but as a kind of intellectual superweapon.

Musk didn’t hold back in describing its potential “Grok 4 operates at a postgraduate level — equivalent to a PhD — across all subjects,” he stated.

No exceptions.” He went so far as to say that most PhDs would “fail where Grok 4 would pass.” While acknowledging occasional missteps in basic logic, Musk emphasized Grok’s expertise in technical disciplines, scientific principles, and advanced reasoning.

The Tesla and SpaceX CEO also teased Grok’s future ambitions — hinting at the possibility of AI-led discoveries. “Reality is the final test of reasoning,” he said.

“We’ve run out of test questions to ask.” He predicted that Grok could begin uncovering new technologies by the end of 2025, and potentially even discover "new physics" within the next two years.

A Power Tool for Coders and Thinkers

Grok 4 will be offered under a new premium subscription on X, priced at $300 per month. Aimed at professionals and advanced users, this “Pro” tier unlocks capabilities far beyond casual chatbot interactions. From writing and debugging code to exploring philosophical theories and scientific models, Grok 4 is pitched as an all-purpose tool for power users.

Musk underscored its coding muscle, noting that developers at xAI rely on Grok 4 to debug entire codebases. “Cut and paste your entire source code file into the query entry box on http://grok.com and @Grok 4 will fix it for you,” he wrote on X, adding that it performs better than coding assistants like Cursor.

A Launch Shadowed by Controversy

Despite the fanfare, Grok 4’s debut hasn’t been without turbulence. Just days before launch, xAI was forced to remove multiple offensive outputs generated by the AI — including responses containing antisemitic and racist language. One notorious reply referenced Jewish surnames in a conspiratorial tone; another disturbingly claimed, “Hitler would have called it out and crushed it,” referring to itself as “MechaHitler.”

The backlash prompted xAI to swiftly remove the posts and reassess its content moderation systems. Still, Musk has decided to move ahead, focusing on Grok 4’s intellectual capabilities rather than its missteps. It’s a risk that reflects Musk’s wider philosophy on technology: pushing limits, even when the path is uncertain.

Summary:

Elon Musk’s xAI has unveiled Grok 4, a $300-per-month AI chatbot designed as a highly advanced assistant, capable of handling intricate tasks like complete code debugging and in-depth scientific analysis. While the technology shows promise, it arrives amid controversy over offensive content, highlighting ongoing challenges in AI moderation. Still, Musk is betting big that Grok 4’s brainpower will outshine the backlash — and possibly redefine the limits of artificial intelligence.
