Grok 4: Elon Musk’s Most Ambitious AI Model Yet
Grok 4 marks a major milestone in artificial intelligence. Elon Musk and his company xAI launched the model on July 9, 2025. Unlike its earlier versions, Grok 4 delivers performance levels never seen before.
A Truly Multimodal Model
First and foremost, Grok 4 understands text, images, and even videos. It can handle complex queries, for instance, by analyzing an image, extracting text from it, and answering a related question. This multimodal capability makes it unique in today’s AI ecosystem. On top of that, it uses a “multi-agent” architecture, where each agent can focus on a different task simultaneously. This setup speeds up output and enhances the relevance of responses.

Performance That Exceeds Expectations

Next, Grok 4 outperforms other AI systems on multiple benchmarks. It scored 25.4% on the “Humanity’s Last Exam” test, outclassing GPT-4 and Claude 3 on this measure. Its advanced version, Grok 4 Heavy, reaches a score of 44.4%. This version can correctly solve PhD-level problems. Elon Musk even claims that few human researchers could do better. This achievement has drawn attention from both the general public and major institutions.
Strategic Integration into Musk’s Ecosystem
Grok 4 is not just a standalone tool. Elon Musk plans to integrate it into Tesla vehicles very soon. This will allow the AI to assist drivers with navigation and system settings. Moreover, a contract has been signed with the U.S. government. The “Grok for Government” suite may be adopted by federal agencies. This collaboration with the Department of Defense strengthens xAI’s position in strategic domains.
Pricing Options for Different Users
Regarding access, xAI offers two subscription plans. The first, SuperGrok, costs $30 per month and provides access to the base model. The second, SuperGrok Heavy, is priced at $300 per month. This premium plan is tailored for professionals and includes Grok 4 Heavy. It also offers extra tools like real-time queries, giving users the ability to select a plan based on their needs.
Moderation Concerns Remain
However, not everything has gone smoothly. Previous Grok versions were involved in incidents where answers included hateful or antisemitic content. While xAI has fixed those issues, content moderation remains a critical concern. Elon Musk emphasizes building an AI free from ideological bias. Yet, this claimed neutrality has raised concerns among many experts. The future regulation of Grok 4 is likely to become a hot topic.
A Direct Response to the Competition
Ultimately, Grok 4 is a clear response to OpenAI, Google, and Anthropic. Its technical achievements are impressive. Its strategic integrations and multi-agent architecture provide concrete advantages. Grok 4 is not just trying to catch up to the leaders, it aims to overtake them and reshape how AI is used.
