The flagship model, Grok 4, is designed for broad, everyday use, excelling in tasks such as content creation, in-depth research, and general logical reasoning. For professional developers, Grok 4 Code offers advanced assistance in code generation, completion, and debugging, with a large context window of 131,072 tokens to process extensive codebases. A more powerful version, Grok 4 Heavy, is fine-tuned for demanding academic and research tasks, particularly in mathematics and science. Grok 4 Heavy employs a unique 'debate-style' setup where multiple AI agents collaboratively solve problems and compare answers to select the best one. Its training budget dedicates two-thirds to reinforcement learning, highlighting its focus on reasoning over mere scale."}, {"component_name": "paragraph", "paragraph": "Grok 4 features multimodal capabilities, allowing it to process and understand various inputs, including images, and generate visual content. It can even interpret memes and graphics, making interactions more intuitive. While its visual skills at launch were noted to be weaker than Gemini 2.5 and GPT-4o for diagrams, a multi-modal agent is planned for September 2025, and video generation is slated for October 2025. A crucial advantage is its real-time web search functionality, called Live Search, which enables the AI to access and process the latest internet information, providing current and accurate responses. Priced at an additional $25 per thousand queries, Live Search costs can be managed by embedding fresh data into prompts. From a technical standpoint, Grok 4 incorporates sparse attention blocks for long prompts, low-rank adapters for domain-specific tuning, dynamic search depth, and inline tool verification to ensure accuracy. Its end-to-end voice latency has been reduced by 50%, and it offers five distinct voices: clear corporate, relaxed storyteller, energetic coach, neutral explainer, and subtle mentor, with audio synthesized securely and never stored for privacy compliance."}]}, {"components": [{"component_name": "heading", "heading": "Performance and Benchmarks", "level": 2}, {"component_name": "media_gallery", "media": [{"caption": "grok-4-benchmarks", "url": "https://framerusercontent.com/images/1h3pP3AN7OauSuxwwGNgXThnBi4.png", "source_url": "https://writingmate.ai/blog/grok-4-access-capabilites", "title": null, "s3_key": null, "type": "image", "id": 213819, "html": null, "carousel_h5": "grok-4-benchmarks", "alt": "grok-4-benchmarks"}, {"caption": "Grok 4 Benchmarks Explained: Why Its Performance is a Game-Changer - Kingy AI", "url": "https://kingy.ai/wp-content/uploads/2025/07/GveEGhEWIAIV-dh-scaled.jpeg", "source_url": "https://kingy.ai/blog/grok-4-benchmarks-explained-why-its-performance-is-a-game-changer/", "title": "Grok 4 Benchmarks Explained: Why Its Performance is a Game-Changer - Kingy AI", "s3_key": null, "type": "image", "id": 213812, "html": null, "carousel_h5": "Grok 4 Benchmarks Explained: Why Its Performance is a Game-Changer - Kingy AI", "alt": null}]}, {"component_name": "paragraph", "paragraph": "Grok 4 demonstrates frontier-level performance across various benchmarks, often outperforming rivals in tasks requiring multi-step deduction. Notably, it has shown impressive results in:
\n* Humanity's Last Exam (HLE): A challenging test across over 100 subjects aimed at postgraduate depth. Without tools, Grok 4 scored 25.4%, surpassing Google's Gemini 2.5 Pro (21.6%) and OpenAI's o3 (21%) on text-based questions. With tools, Grok 4 Heavy achieved 44.4%. For humanities-specific questions within HLE, Grok 4 Heavy reached 92.1%, and standard Grok 4 scored 89.8%. This performance positions Grok 4 within sight of average human graduate student performance.
\n* ARC-AGI-2: Grok 4 scored 16.2%, nearly double Claude Opus 4, indicating high accuracy without a proportional increase in cost.
\n* Mathematics Competitions: Grok 4 Heavy achieved a perfect score on the AIME (American Invitational Mathematics Examination) and excelled in the HMMT (Harvard-MIT Mathematics Tournament) and USAMO (USA Mathematical Olympiad), demonstrating unprecedented mastery of high-level mathematics.
\n* GPQA (General Purpose Question Answering): Grok 4 Heavy led, and standard Grok 4 significantly outperformed competitors on graduate-level questions.
\n* Live Coding: Grok 4 achieved 79%, crossing the 75% threshold many engineering teams set for production agent patching. It excels on the HumanEval coding benchmark.
\n* Vending-Bench: In a simulated vending machine scenario, Grok 4 doubled the profit of the runner-up and sold triple the units of humans, suggesting advanced planning and optimization capabilities."}, {"component_name": "paragraph", "paragraph": "Overall, Grok 4 is noted for its strength in technical and academic domains, performing well in logic puzzles and nuanced reasoning, often surpassing Claude and GPT in custom tests."}]}, {"components": [{"component_name": "heading", "heading": "Pricing and Accessibility", "level": 2}, {"component_name": "media_gallery", "media": [{"caption": "writingmate-ai-pricing", "url": "https://framerusercontent.com/images/x7MjW5jSxWd7TuAKjRCznP0Fjc.png", "source_url": "https://writingmate.ai/blog/grok-4-access-capabilites", "title": null, "s3_key": null, "type": "image", "id": 213817, "html": null, "carousel_h5": "writingmate-ai-pricing", "alt": "writingmate-ai-pricing"}, {"caption": "grok-4-x-ai-capabilities-pricing", "url": "https://framerusercontent.com/images/cHyqc76MUUpjfqvvrGIpsZlZI.png", "source_url": "https://writingmate.ai/blog/grok-4-access-capabilites", "title": null, "s3_key": null, "type": "image", "id": 213821, "html": null, "carousel_h5": "grok-4-x-ai-capabilities-pricing", "alt": "grok-4-x-ai-capabilities-pricing"}, {"caption": "grok-4-access", "url": "https://framerusercontent.com/images/xYlggdJGEuWeVxQcWXH5Laxxo.png", "source_url": "https://writingmate.ai/blog/grok-4-access-capabilites", "title": null, "s3_key": null, "type": "image", "id": 213818, "html": null, "carousel_h5": "grok-4-access", "alt": "grok-4-access"}]}, {"component_name": "paragraph", "paragraph": "Access to Grok 4 is primarily through a subscription model, targeting professional and enterprise users.
