x-ai/grok-4.3

發布時間: 2026-05-01

1,000,000 context · $1.25/M input tokens · $2.50/M output tokens

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.
