xAI launches Grok 4 and the multi-agent Grok Heavy system, setting new benchmarks in AI reasoning and tool integration. The SuperGrok Heavy subscription, priced at $300/month, becomes the most expensive AI subscription to date.
Grok Heavy Multi-Agent System: Continuing its revolutionary strides in the world of artificial intelligence, Elon Musk's AI research company, xAI, has unveiled its new and advanced models, Grok 4 and the Grok Heavy Multi-Agent System. Notably, the company has also launched the world's most expensive AI subscription plan to date, priced at $300, approximately ₹25,700 per month.
Grok 4: A New Super Intelligent AI Model
xAI's new model, Grok 4, is a large language model (LLM) that surpasses many existing leading AI models. It was recently presented via a live stream on X (formerly Twitter), where Elon Musk himself and xAI developers provided a detailed description of its capabilities. Musk claims that Grok 4 possesses a PhD-level understanding and reasoning power across all subjects. This model not only provides accurate answers to technical questions but also excels in complex fields such as humanities, arts, history, and ethics.
Grok 4 Shines in Humanities Last Exam
Grok 4 was tested in a special exam called the 'Humanities Last Exam'. This examination comprises 2,500 questions that test the AI's reasoning, knowledge, and understanding across various fields. According to xAI, Grok 4 scored 25.4% in this exam. This score is better than Google Gemini 2.5 Pro (21.6%) and OpenAI's o3-High (21%). This indicates that this new model is not only fast but also a leader in multi-dimensional thinking.
Grok Heavy: A Multi-Agent Super System
xAI has introduced another powerful system called Grok Heavy, designed as a multi-agent system. This is an AI framework where multiple expert agents work together to generate multiple solutions to a problem, and then the most suitable and effective solution is selected. Although the company has not shared detailed technical information about Grok Heavy, it seems similar to models from open-source agent frameworks like Sakana AI. Its specialty is that it adopts a teamwork-based decision-making process that can provide better solutions to complex problems.
New Record in Performance with Tools
The performance of Grok Heavy is even more impressive. When tested with tools, its score was 44.4%, which is much higher than OpenAI o3 with Deep Research (26%) and Gemini 2.5 Pro with tools (26.9%). This means that Grok Heavy is not only capable of better thinking but also produces higher-quality output when working with analytical tools.
SuperGrok Heavy: The Most Expensive AI Subscription
The most surprising aspect of this technology launch is xAI's new subscription plan, SuperGrok Heavy, priced at $300/month (₹25,700). This is the most expensive consumer AI subscription plan to date.
This plan is specifically designed for users who use AI extensively for professional or research purposes. It offers them:
- Advanced features like Grok Heavy
- Early access
- High-performance capacity
- Faster and more accurate output
as premium features.
Direct Integration on the X Platform
Grok 4 and Grok Heavy are being integrated into the X (formerly Twitter) platform, where users can take advantage of these AI tools directly on the social media interface. This move is part of Musk's plan to transform X from a traditional social media platform into an AI-enabled knowledge platform.
What Does This Launch Indicate Regarding the Direction of AI?
This new launch by Elon Musk clearly indicates that xAI is not just a competitive company but has a mission to redefine the future of AI. With the arrival of Grok 4 and Grok Heavy, companies like OpenAI, Google, and Meta could face serious competition.
