Grok 4

Grok 4 is the latest artificial intelligence model launched by xAI, featuring multiple notable characteristics aimed at enhancing reasoning capabilities and user experience.

Model Versions

Grok 4: This is the single-agent version focused on reasoning and text generation. The model performed well on the "Humanity's Last Exam," achieving approximately 25% accuracy, demonstrating its strong capabilities across multiple disciplines.

Grok 4 Heavy: This is the multi-agent version, supporting four agents working in parallel to handle more complex reasoning tasks. This version utilizes greater computational resources to manage more sophisticated tasks and improve overall performance.

Key Features

Multimodal Capabilities: Grok 4 can process and generate various data types, including text and images, supporting more complex interaction formats. This makes it widely applicable in creative content generation, scientific research, and medical imaging.

Enhanced Reasoning Ability: The model adopts an axiom-based reasoning method, providing stronger logical consistency and analytical power. Grok 4 performed exceptionally on the "Humanity's Last Exam," showing a high level of understanding across subjects such as mathematics, science, and the humanities.

Context Window: Grok 4 supports a context window of up to 256,000 tokens, significantly enhancing its ability to handle complex tasks.

Programming Support: Grok 4 introduces a dedicated programming version, Grok 4 Code, which provides a real-time integrated development environment (IDE), supporting code generation, debugging, and file editing to boost developer productivity.

Real-Time Data Access: Grok 4 can access real-time data from the xAI ecosystem (such as X, Tesla, and SpaceX), enhancing its applicability in social media analysis and automotive system integration.

Voice Capabilities: The model is equipped with an advanced voice mode capable of simulating human emotions, offering a more natural interactive experience. A new voice option, "Eve," can quickly switch tones and even perform singing.

Subscription Model: The basic version of Grok 4 is available for a subscription fee of $30 per month, while the more powerful Grok 4 Heavy version costs $300 per month. The latter supports multi-agent parallel processing, suitable for complex reasoning and deep analysis.

Application Scenarios
