Kie AI 上的 GPT 对话 API
Kie AI 用同一个 API 密钥提供 GPT 对话模型和 Codex。以下是 GPT 对话 API 目前支持的能力，以 Kie AI API 文档为准。
兼容 OpenAI Responses 的接口
请求发送到 POST https://api.kie.ai/codex/v1/responses，模型 ID 填上表中的型号，如 gpt-6-1-sol。接口沿用 OpenAI Responses 格式（含 response.* 流式事件），Codex 也用同一个接口；支持的请求字段以 Kie AI API 文档为准。
可调推理强度
每个请求可选 low、medium、high、xhigh 或 max 推理强度，在速度、深度和费用之间取舍。
联网搜索或函数调用，并支持结构化输出
可以给模型开启内置联网搜索获取最新信息，或传入你自己的函数工具用于智能体流程（同一请求二选一）；需要稳定可解析的结果时，可要求按 JSON Schema 严格输出。
文本、图片和文件输入
一条消息里可同时包含文本、图片和文件。GPT 6.1 Sol 的上下文窗口为 272K token。
