可直接貼上執行下方範例程式碼。Gate.AI API 與 OpenAI 相容，多數 SDK 只需替換 base URL；切換模型時，只需修改模型 ID。
Sign in to the Gate.AI console and create a new key under "API Keys". Keep it safe and send it via the Authorization header on every request.
前往控制台建立金鑰Send a POST request to the Chat Completions endpoint with a model ID and an array of messages to get a reply.

Grok 4.6Grok's agent-oriented release, built for long-running multi-step work across a codebase. Accepts text, image, and file inputs. Suited for research and interactive or visual output.
Grok 4.3Grok 4.3 is a reasoning model from xAI that supports text and image inputs with text output. It is suited for agentic workflows, instruction following, long-document analysis, and deep research. The model supports a 1M token context window. Requests above 200K total tokens are billed at a higher rate.
