The next evolution in artificial intelligence from xAI
Grok4 represents a quantum leap in AI capabilities, developed by xAI under the visionary leadership of Elon Musk. Unlike traditional language models, Grok4 is built on first-principles reasoning and designed to "rewrite the entire human knowledge base" by eliminating inaccuracies and adding missing information.
Built on xAI's massive Colossus supercomputer infrastructure with over 100,000 GPUs, Grok4 delivers unprecedented computational power. This infrastructure enables real-time processing, advanced reasoning capabilities, and seamless integration across multiple platforms.
Grok4 is xAI's first model to integrate flagship language, vision, and coding capabilities into a unified API. With specialized models like Grok4 Code for development tasks and enhanced reasoning modes, it's designed to be the perfect "Swiss Army knife" for both daily conversations and enterprise applications.

Everything you need to know about Grok4
Grok4 is the next-generation AI language model developed by xAI, led by Elon Musk. It's designed as a versatile "Swiss Army knife" for daily conversations and enterprise applications, featuring advanced reasoning capabilities, real-time data access, and multi-modal support for text, vision, and code generation.
Grok4 is expected to be released after July 4, 2025. Some API endpoints are already available, indicating a phased rollout strategy. The model represents a significant upgrade from Grok 3, skipping the originally planned Grok 3.5 version.
Grok4 directly competes with leading AI systems like ChatGPT, Claude, and Gemini. It excels in mathematical reasoning (AIME 2025: 52 points vs GPT-4o's 48), scientific knowledge (GPQA: 75 points), and coding tasks (LCB: 57 points). Its key advantages include real-time data access, 130K token context window, and specialized enterprise knowledge.
Key features include: Advanced reasoning based on first-principles physics, 130,000 token context window, DeepSearch for real-time internet and X platform data, specialized Grok4 Code for programming tasks, Think Mode for step-by-step reasoning, and upcoming multi-modal support for vision and image generation.
Grok4 Code is a specialized model designed as a "coding companion" for advanced IDE integration and built-in file editors. It can answer code-related questions, integrate directly into code editors through Cursor, and features a VSCode-like interface within the Grok web platform for seamless development workflows.
Think Mode allows users to track Grok4's step-by-step reasoning process, making its logic transparent and verifiable. Big Brain Mode is designed for complex problem-solving tasks requiring extended reasoning capabilities. Both features enhance the model's ability to handle sophisticated analytical tasks.
Yes, Grok 4 currently offers limited-time free access to all users without requiring a subscription.
Grok 4 has already started offering limited-time free access.
Pricing tiers include: Free access (limited daily usage), X Premium+ ($40/month or $32.92/month annually) with advanced Grok features, SuperGrok subscription ($30/month or $300/year) for pure AI functionality, and Enterprise API with custom pricing. API costs approximately $0.03 per request for standard tier.
Grok4 will be accessible through xAI's API, integrated platforms including X (formerly Twitter), mobile devices (iOS, Android), and web (grok.com). It will also integrate with Tesla vehicles and potentially with brain-computer interfaces and Optimus robots in the future.
X Premium+ includes full X features plus advanced Grok capabilities and early access to new features. SuperGrok is "pure Grok" designed specifically for AI work, offering more features, roles, workspaces, higher image generation limits, priority access, and advanced AI tools without X platform integration.
Grok4 features a 130,000 token context window (up from Grok 3's 32,000), advanced reasoning based on first-principles physics, real-time data processing through DeepSearch, and is trained on xAI's Colossus supercomputer with 100,000+ GPUs. It supports JSON communication, chat completion, and image understanding.
Grok4 is built on xAI's Colossus supercomputer, constructed in less than nine months using over 100,000 hours of NVIDIA GPU processing time. The facility houses 200,000 GPUs, with plans to expand to 1 million GPUs, requiring massive procurement from NVIDIA and AMD.
Initially, Grok4 supports text modality with plans to quickly introduce comprehensive vision and image generation capabilities. It will be xAI's first model to integrate flagship language, vision, and coding capabilities into a unified API, supporting multiple languages and technical domains.
Yes, Grok4 excels in enterprise use cases including data extraction, coding, and text summarization. It has deep expertise in finance, medical, legal, and scientific domains. The grok-4-prod-mimic model is specifically designed for enterprise applications with professional-grade API and custom integrations.
Grok4 API includes REST API with JSON communication, chat completion, image understanding models, authentication via bearer tokens, and customizable parameters like temperature, max tokens, top_p, frequency penalty, and presence penalty. Enterprise customers get custom pricing and high-throughput access.
Yes, Grok4 Code is designed for advanced IDE integration and works seamlessly with Cursor. It features built-in file editors and can be embedded directly into development environments. The model supports various programming languages and can assist with code review, debugging, and optimization.
xAI has developed a comprehensive risk management framework including malicious use prevention, safeguard measures like refusal training and "circuit breakers," input/output filtering for harmful content, and regular adversarial testing. The system includes customizable safety modes including NSFW and child-safe modes.
xAI's privacy policy states they don't collect personal information for marketing purposes or share it with third parties for marketing. However, due to the model's technical complexity, they cannot guarantee factual accuracy of outputs or correct factually incorrect personal information.
Grok4's mission to "rewrite the entire human knowledge base" raises concerns about potential bias and factual manipulation. Critics worry about the model potentially distorting public perception and blurring lines between factual reporting and personal bias. xAI is committed to transparency and third-party auditing to address these concerns.
