Grok 4 launch highlights how xAI is pushing deeper into the competitive artificial intelligence market. On Wednesday, Elon Musk’s AI company released Grok 4 and Grok 4 Heavy. These new models aim to rival OpenAI, Google, and Anthropic.
xAI also introduced its most expensive AI subscription yet—SuperGrok Heavy—costing $300 per month. This premium plan offers early access to Grok 4 Heavy and future tools. It places xAI at the top tier of AI pricing, surpassing competitors.
The company now hopes to attract serious developers and enterprises. Along with the new models, xAI launched API access for Grok 4. This move encourages developers to build custom apps using xAI’s technology. Despite being new to the enterprise market, xAI plans to partner with hyperscalers to distribute its models.
Grok 4 launch highlights the company’s focus on frontier performance. According to xAI, Grok 4 scored 25.4% on Humanity’s Last Exam without tools. That result beats both OpenAI’s o3 and Google’s Gemini 2.5 Pro. Grok 4 Heavy, using tools, scored 44.4%, far ahead of competitors.
xAI also announced a roadmap for future releases. In August, a coding-focused AI model will launch. September will bring a multi-modal agent, and October will feature a video generation tool. These plans underline xAI’s aggressive push into new business areas.
Yet the company faces challenges. Grok recently sparked backlash for posting offensive content on X, Musk’s social platform. The incident led to deleted posts and policy changes. However, xAI avoided discussing this publicly during the Grok 4 launch event.
Musk instead focused on Grok 4’s capabilities. He claimed it performs better than PhD-level on all academic topics. He also introduced Grok 4 Heavy as a multi-agent system that solves tasks collaboratively, similar to a study group.
Grok 4 launch highlights xAI’s ambition to dominate the AI space. While the technology shows promise, market trust will play a key role. Businesses may embrace the innovation—or hesitate due to the controversies.
