Grok 4.3 API

x-ai/grok-4.3

Grok 4.3 is xAI’s advanced reasoning model designed for agentic workflows, complex instruction-following, and high-accuracy knowledge tasks. It supports both text and image inputs, generating text outputs with configurable reasoning depth across none, low, medium, and high effort modes (default: low). The model features an industry-leading 1 million token context window with no fixed output token limit, enabling long-document analysis, deep research, multi-step reasoning, and large-scale autonomous agent applications. Pricing is usage-tiered, with higher rates applied to requests exceeding 200K total tokens.
