Elon Musk’s AI company, xAI, just dropped its newest AI model, Grok 4, along with a premium $300-a-month subscription plan called SuperGrok Heavy.
People who sign up for the SuperGrok Heavy plan will get early access to Grok 4 Heavy and new features before everyone else. It’s kind of like the top-tier plans offered by OpenAI, Google, and Anthropic — but xAI’s version is now the priciest out of all of them.
Subscribers might also be the first to try out some of xAI’s upcoming tools. The company said it’s planning to release an AI coding model in August, a multi-modal agent in September, and a video generation model in October.

xAI launched two versions — Grok 4 and a more advanced one called Grok 4 Heavy. Musk explained that Grok 4 Heavy works by using multiple AI “agents” to tackle a problem at once, and then they compare answers, kind of like a study group, to pick the best one.
“With respect to academic questions, Grok 4 is better than PhD level in every subject, no exceptions,” said Elon Musk during a livestream Wednesday night. “At times, it may lack common sense, and it has not yet invented new technologies or discovered new physics, but that is just a matter of time.”
This new Grok 4 launch from xAI clearly seems like a direct response to what OpenAI and Google have been doing with their own AI models — ChatGPT and Gemini. Just like them, Grok 4 can now analyze images and answer questions about them, which shows that xAI is trying to close the gap and stay in the same league when it comes to cutting-edge AI features.
Meanwhile, OpenAI CEO Sam Altman threw a subtle jab at Elon Musk while talking to The New York Post about Musk’s messy situation with Donald Trump. This happened during the annual Sun Valley “summer camp for billionaires.” When Altman was asked if he supported Musk’s new political plans, he replied, “I don’t know. I haven’t had a chance to read about it”.
Back in January, Sam Altman showed up at the White House alongside Trump to back the Stargate AI project — a massive $500 billion federal push into AI and national infrastructure.

Altman and Musk actually started OpenAI together in 2015, but things fell apart in 2018 after clashing over the company’s future — especially over keeping it non-profit. That disagreement led Musk to walk away and now they are long-time rivals.
Now, Musk and Trump is also falling out. Musk’s recent launch of the “America Party,” a third-party political move, has shaken things up and could make Trump’s path to the 2026 midterms a lot trickier.
