- xAI has launched the brand new Grok 4 and Grok 4 Heavy AI fashions
- Grok 4 requires a $30 month-to-month SuperGrok subscription
- The launch comes as Grok faces renewed criticism
xAI launched new variations of its Grok AI mannequin line. Grok 4 and its bigger, extra highly effective sibling, Grok 4 Heavy, are a part of CEO Elon Musk’s effort to place Grok as a critical competitor to OpenAI’s ChatGPT, Google’s Gemini, and Anthropic’s Claude. That features the brand new $300-a-month subscription tier referred to as SuperGrok Heavy, which affords unique entry to Grok 4 Heavy.
Musk boasted in the course of the announcement livestream that “Grok 4 is healthier than PhD stage in each topic, no exceptions. At occasions, it could lack frequent sense, and it has not but invented new applied sciences or found new physics, however that’s only a matter of time.”
And the mannequin’s benchmark scores do counsel it isn’t hyperbolic to say so; it is a authentic leap ahead. Grok 4 scored 25.4% on the notoriously troublesome Humanity’s Final Examination benchmark with out instruments, placing it forward of Gemini 2.5 Professional and OpenAI’s o3. The bragging is much more apt for Grok 4 Heavy, as a result of as a multi-agent model of Grok 4, it deploys a number of reasoning brokers concurrently. On the identical take a look at, it scored 44.4%, higher than all present business choices.
The takeaway, at the very least from a technical standpoint, is that Grok 4 is now firmly in frontier-model territory. That’s a significant shift for xAI, which simply months in the past was primarily recognized for its integration with X, the rechristened Twitter owned by Musk. xAI is clearly making an attempt to be taken significantly as a authentic AI analysis and enterprise firm.
If you happen to do pay the $300 a month for SuperGrok Heavy, you may get not solely entry to Grok 4 Heavy but in addition developer instruments, API utilization, and be first to check out new and upcoming options like an AI coding assistant, a multi-modal agent, and an AI video generator. As OpenAI, Google, and Anthropic all roll out costlier subscription tiers, xAI is prone to be eager to come back out forward in each timing and mannequin high quality.

Grokking controversy
In fact, the benchmarks and demos shared by Musk and his workforce in the course of the livestream couldn’t fairly overshadow how Grok’s official account on X this week spiraled into antisemitic insanity.
The chatbot’s automated replies on X for hours included conspiracy theories about Jewish management of Hollywood, reward for Hitler, and even declaring itself as “MechaHitler.” The corporate swiftly deleted the posts as they appeared, and Grok briefly denied even making them earlier than copping to the truth of screenshots.
Finally, X deleted the entire eye-poppingly offensive posts and positioned non permanent restrictions on the account. The outburst seemed to be tied to a current replace to Grok’s inside system immediate that the corporate then reversed.
Musk didn’t tackle the incident straight throughout his Grok 4 livestream, nor did anybody at xAI supply a public clarification. In the meantime, Linda Yaccarino stepped down as CEO of X on the exact same day, although xAI insists the timing is unrelated.
With all that occuring within the background, Grok 4’s launch did not have fairly the clear innovation-centered debut xAI possible hoped for. And it is exhausting for the corporate to say the reward for Hitler was merely a technical error when Musk, who’s intimately tied to each X and xAI, has repeatedly insisted that Grok will likely be a non-politically right AI mannequin.
You’ll be able to construct probably the most highly effective mannequin on this planet, but when customers are continually bracing for it to say one thing offensive or unhinged, that energy received’t matter.
There’s no query xAI has the technical chops to construct a top-tier mannequin. However except they begin addressing belief, transparency, and content material security with the identical depth they apply to benchmarks, they’ll all the time be enjoying catch-up to corporations with AI chatbots that do not remind individuals of main public relations disasters.
An organization all in favour of what Grok 4 Heavy can do for them is perhaps a bit of extra hesitant to pay $300 a month if the very first thing individuals consider once they hear about Grok powering the system is Holocaust denial. That sort of baggage is heavier than any dataset.
