Grok 4

What is Grok 4?

Grok 4 is the latest version of the large language model developed by Elon Musk's AI company, xAI. It officially launched on July 9, 2025, with a livestream event hosted on xAI's official X account. Named after Robert A. Heinlein's concept from "Stranger in a Strange Land," Grok 4 represents a significant leap forward, skipping the previously expected Grok 3.5 release to accelerate progress amid intense AI competition.

Grok 4 is xAI’s most advanced large language model, designed for users who demand both reasoning and performance. It introduces first-principles reasoning, improved logical consistency, and deeper analytical capabilities. It also features comprehensive multimodal support, initially supporting text, with vision and image-generation features expected soon. A specialized coding edition (Grok 4 Code) offers enhanced integration into developer workflows with real-time IDE capabilities.

Benefits

Grok 4 offers several key advantages:

• Advanced Reasoning: Grok 4 introduces first-principles reasoning, improved logical consistency, and deeper analytical capabilities, making it a powerful tool for complex problem-solving.
• Multimodal Support: Initially supporting text, Grok 4 is expected to soon include vision and image-generation features, allowing for more versatile applications.
• Coding Support: The specialized Grok 4 Code edition offers enhanced integration into developer workflows with real-time IDE capabilities, making it a valuable tool for programmers.
• Native Tool Use: Grok 4 was trained with reinforcement learning to use tools, allowing it to augment its thinking with tools like a code interpreter and web browsing, which is particularly useful for real-time information and difficult research questions.
• Frontier Intelligence: Grok 4 sets a new state-of-the-art for closed models on ARC-AGI V2 and other benchmarks, demonstrating unparalleled capabilities in complex reasoning.
• Voice Mode: The upgraded Voice Mode features enhanced realism, responsiveness, and intelligence, allowing users to interact with Grok in a more natural and intuitive way.

Use Cases

Grok 4 can be used in various scenarios, including:

• Advanced Research: Grok 4 can solve PhD-level questions, making it a valuable tool for advanced research in mathematics, physics, and engineering.
• Business Planning: It can help map out strategies and perform advanced business analysis to provide actionable insights.
• Coding and Writing Tasks: The specialized Grok 4 Code edition offers enhanced integration into developer workflows with real-time IDE capabilities, making it a valuable tool for programmers.
• Real-Time Social Media Interaction: Integrated directly into X (formerly Twitter) as a chatbot, Grok 4 can generate memes, posts, polls, summaries, or sentiment analysis.

Pricing

Grok 4 is available in two versions: the normal version and Grok 4 Heavy, a multi-agent version where multiple agents collaborate to generate the best results. It is available under the Super Grok plan and the Super Grok Heavy plan, with the latter offering an enhanced context window and early access to new features. The Super Grok plan is priced at $30/month or $300/year, while the Super Grok Heavy plan is priced at $300/month or $3,000/year.

Vibes

Grok 4 has shown impressive performance on various benchmarks, including GPQA (Graduate-Level Physics Questions Archive), AIME (American Invitational Mathematics Examination) 2025, and SWE-Bench (Software Engineering Benchmark). It has also performed well on new benchmarks like ARC-AGI and Vending Bench, demonstrating its capabilities in complex reasoning and real-world decision-making.

Grok 4 has been designed to be a legitimate AGI contender, with benchmarks showing it outperforming competitors like GPT-4o and Claude 3.5 Sonnet. It has achieved an all-time high of 88% on GPQA Diamond and 24% on Humanity's Last Exam, leading in coding and math benchmarks. However, it is important to note that while Grok 4 is incredibly powerful, it also comes with risks, particularly in terms of potential hate speech and controversial content. xAI has faced challenges in ensuring the safety and appropriateness of Grok's responses, and businesses considering deploying Grok 4 on the API should be aware of these risks.

Additional Information

xAI will continue scaling reinforcement learning to unprecedented levels, building on Grok 4's advancements to push the boundaries of artificial intelligence. They plan to expand the scope from verifiable rewards in controlled domains to tackling complex real-world problems, where models can learn and adapt in dynamic environments. Multimodal capabilities will see ongoing improvements, integrating vision, audio, and beyond for more intuitive interactions. Overall, their focus remains on making models smarter, faster, and more efficient, as they drive toward systems that truly understand and assist humanity in profound ways.
