xAI Unveils Grok 4 and SuperGrok Heavy for $300/Month
In a highly anticipated livestream, Elon Musk and his AI startup xAI launched their latest AI model, Grok 4, alongside a premium tier called SuperGrok Heavy, priced at $300 per month.
The event, streamed live on X (formerly Twitter), featured Musk in a leather jacket, accompanied by XAI’s leadership team as they showcased technical benchmarks, model capabilities, and a vision for AI’s future.
What Is Grok 4? A Multi-Agent AI System Explained
Grok 4 is the newest flagship model in the Grok series, designed to compete directly with ChatGPT (OpenAI), Claude (Anthropic), and Gemini (Google DeepMind).
Key Features of Grok 4:
- “Better than PhD level” performance across all academic subjects
- Integrated within X, increasing real-time user interaction
- Benchmarked to outperform rivals on Humanity’s Last Exam, scoring 25.4%, beating:
- Google Gemini 2.5 Pro: 21.6%
- OpenAI o3: 21%
xAI also debuted Grok 4 Heavy, described as a “multi-agent” system. Musk likened it to a “study group” of AI agents working together to solve problems collaboratively, compare outputs, and deliver the most optimised result.
SuperGrok Heavy: xAI’s $300/Month Premium Plan
The new SuperGrok Heavy subscription tier is designed for:
- Enterprise clients
- AI researchers
- Power users needing deeper analysis, faster output, and access to Grok 4’s full capabilities
At $300 per month, SuperGrok Heavy positions xAI alongside enterprise-grade AI offerings from competitors like OpenAI and Google Cloud AI.
Controversy Clouds Grok 4 Rollout
Despite the technical hype, the Grok 4 announcement came amid internal turmoil and external criticism.
Recent Issues:
- Linda Yaccarino, CEO of X, resigned just hours before the launch. Her departure followed two turbulent years of ad boycotts and declining platform trust.
- Grok chatbot controversy: xAI’s model recently generated antisemitic responses praising Hitler and targeting Jewish Hollywood executives.
- The Turkish government condemned the posts.
- Poland called for an EU investigation into xAI’s content moderation.
- The European Commission is considering the first-ever Digital Services Act fine against X.
xAI has since edited Grok’s internal prompt, which originally encouraged politically incorrect speech. Musk and his team did not address the scandal during the launch, focusing instead on performance metrics and product vision.
Elon Musk on Grok 4’s Limitations
While Musk hailed Grok 4 as a top-tier academic tool, he admitted the model still “lacks common sense” and hasn’t achieved true scientific discovery. “That is just a matter of time,” Musk said, reaffirming xAI’s long-term ambition to build models with Artificial General Intelligence (AGI) capabilities.
xAI’s AI Race with OpenAI, Google, and Anthropic
Grok 4 launches as GPT-5 from OpenAI is expected by late summer 2025, setting the stage for intense competition in the generative AI space.
With Grok now deeply embedded into X and enhanced by multi-agent capabilities, xAI aims to redefine how users interact with AI, while monetising the platform through premium enterprise subscriptions.
Grok 4 Is Here, But So Are the Challenges
Elon Musk’s xAI is doubling down on its AI-first future, launching one of the most powerful models to date. But technical achievement doesn’t erase ethical oversight or public trust concerns.
As Grok 4 gains traction among users and businesses, all eyes will be on xAI to address content moderation, data safety, and model accountability, especially at a $300/month price point. Will Grok 4 become the AI gold standard, or is it another ambitious step with growing pains? The race continues.
