About Grok 4.6
Key Features
<strong>Long-Running Agent Capabilities.</strong> Grok 4.6 stays with complex tasks across many steps, whether researching a topic, analyzing information, or working across a codebase to turn ideas into polished applications.
<strong>500K Token Context Window.</strong> The model handles up to 500,000 tokens of context, making it suitable for processing large documents, annual reports, transcripts, and extensive codebases without chunking.
<strong>Configurable Reasoning Effort.</strong> Developers can select low, medium, high, or xhigh reasoning effort through the API, allowing the model to think before responding and tackle complex multi-step problems.
<strong>Multimodal Input Support.</strong> Grok 4.6 accepts text and images as input, enabling it to analyze screenshots, charts, diagrams, and PDFs alongside written context for richer reasoning tasks.
<strong>Structured Outputs and Function Calling.</strong> The model can return responses in specific organized formats and connect to external tools and systems through function calling, making it practical for building applications.
<strong>Competitive Pricing Model.</strong> Priced at $2 per million input tokens and $6 per million output tokens, Grok 4.6 offers frontier performance at roughly half the cost of comparable models like GPT-5.6 Sol.
