创建目录（注意目录名包含前缀 .）：
%USERPROFILE%\\.codex\\在 %USERPROFILE%\\.codex\\config.toml 写入：
model_provider = "letairun"
model = "gpt-5.4"
model_reasoning_effort = "xhigh"
disable_response_storage = true

codexCodex 扩展后即可使用codex 提示命令不存在：
npm 安装时，确认全局安装目录已加入 PATH。auth.json 文件名和路径是否正确。OPENAI_API_KEY 的值不是示例占位符。config.toml 中 base_url 是否为 https://api.letai.run/v1。
