Late on July 9, Elon Musk introduced Grok 4 and its more powerful counterpart, Grok 4 Heavy, positioning them as the dawn of what he calls the era of “Big Bang Intelligence.” A key motivation behind this launch was to overcome the shortcomings of earlier models, including their tendency to produce antisemitic remarks.
“Grok 4 is the first time, in my experience, that an AI has been able to solve difficult, real-world engineering questions where the answers cannot be found anywhere on the Internet or in books. And it will get much better,” Musk stated on social media shortly after the launch.
Since then, he has actively engaged with users, responding to feedback and sharing updates about the models.
What Are Grok 4 and Grok 4 Heavy?
These newly released AI models from xAI are designed to rival OpenAI’s GPT-5 and Google’s Gemini in terms of speed, precision, and creativity. While previous iterations drew criticism for circulating offensive and antisemitic outputs, the Grok 4 models aim to address such content moderation concerns while maintaining xAI’s commitment to open expression.
Key Features of Grok 4 and Grok 4 Heavy
- Cultural Fluency:
According to Tom’s Guide, the models are now better attuned to internet culture, memes, and humor, offering more relatable and accurate interpretations. - Real-Time Web Access (DeepSearch):
With DeepSearch, Grok 4 can browse the internet in real-time, especially leveraging data from X (formerly Twitter), for the most current results. - Human-like Voice Output:
The voice capabilities in Grok 4 mimic natural human speech with smoother flow and fewer interruptions. - Multimodal Processing:
Capable of handling both text and images simultaneously, Grok 4 addresses prior limitations and is reportedly being developed to support video input as well. - Enhanced Coding Abilities:
Developers will find Grok 4 particularly useful for programming, as it can write, debug, and explain code with a level of efficiency similar to GitHub Copilot and GPT-4 Code Interpreter. - Advanced Reasoning:
Powered by xAI’s Colossus supercomputer, the model demonstrates strong scientific reasoning, logic, and coherent text generation.
As The Decider reports, Grok 4 is currently priced at $30/month, while the premium ‘SuperGrok Heavy’ subscription—granting access to Grok 4 Heavy and future upgrades—costs $300/month.
