Elon Musk is once again shaking up the AI world with the official launch of Grok 4, the latest version of his artificial intelligence model under xAI. Announced during a livestream on X (formerly Twitter), Musk described Grok 4 as the “smartest AI in the world.” And he’s backing that claim with a premium version that comes with a $300/month subscription, called SuperGrok Heavy.
Grok 4 vs the Rest: Beating ChatGPT and Gemini in Benchmarks
xAI revealed that Grok 4 outperformed top AI models like ChatGPT and Gemini 2.5 Pro on a benchmark test known as Humanity’s Last Exam, which features over 2,500 questions across subjects like math, science, and language.
- Grok 4 scored 25.4%, beating:
- Gemini 2.5 Pro at 21.6%
- OpenAI’s o3 at 21%
But it doesn’t stop there. The upgraded version, Grok 4 Heavy, scored 44.4%, outperforming Gemini 2.5 Pro by a wide margin. This version is described as a multi-agent model where multiple AI agents collaborate to solve a problem and choose the best solution from among themselves.
AI That Can Reason, Analyze Images & Solve Real-World Problems
Grok 4 isn’t just smarter on paper. According to Musk, it’s capable of solving complex engineering problems where the answers don’t exist online or in books. The model also brings image recognition and visual analysis into play, adding even more power to its reasoning capabilities.
Musk wrote on X, “This is the first time I’ve seen an AI solve real-world problems that aren’t searchable. And it’s only going to improve from here.”
SuperGrok Heavy: What You Get for $300 a Month
For serious AI enthusiasts or professionals, the SuperGrok Heavy subscription offers access to the high-performance, multi-agent version of Grok. Priced at $300/month, this premium tier is designed to give users cutting-edge capabilities, faster outputs, and superior reasoning — ideal for businesses, researchers, or developers working on next-gen applications.
The Rollout Amid Controversies and Changes
The launch of Grok 4 arrives at a tense moment for Musk’s companies. Just a day before the reveal, X CEO Linda Yaccarino resigned from her position after two years of leading the platform. Moreover, Grok made headlines earlier this week for generating offensive content on X — a controversy that followed Musk’s public comments about the AI becoming “too politically correct.”
Despite these hiccups, the Grok 4 release reflects Musk’s aggressive push to position xAI as a top contender in the artificial intelligence race, directly challenging OpenAI and Google.
What’s Next for Grok 4?
With enhanced reasoning, multi-agent architecture, and image capabilities, Grok 4 is certainly making waves. As more users begin exploring the AI through the new SuperGrok subscription, time will tell whether it can live up to the bold claims of being the smartest AI in the world.
Would you pay $300 a month to access the most advanced AI tool out there? That’s the big question as xAI’s Grok 4 gears up to redefine what artificial intelligence can achieve.
