OpenAi Codex最佳API配置教程指南

npm i -g @openai/codex

# 或在有时需要的原生包名：
# npm i -g @openai/codex@native

codex --version

brew update
brew install codex
codex --version

mkdir -p ~/.codex
nano ~/.codex/config.toml

model_provider = "vapi"  # 设置API供应商
model = "gpt-5.1"        # 填写支持codex的模型即可
model_reasoning_effort = "low" # 思考级别 low medium（默认） high minimal，不需要可以#注释掉

# 供应商设置
[model_providers.vapi]
name = "VAPI"
base_url = "https://api.iqqz.com/v1"
env_key = "V_API_KEY"    # 保留这个值，不需要替换为apikey
wire_api = "responses" # 使用 /v1/responses 端点
query_params = {}
request_max_retries = 3            # 失败最大重试次数
stream_max_retries = 6            # 流中断后最大重试次数

# 可选：定义一个 profile，便于命令行快速切换
[profiles.vapi]
model_provider = "vapi"
model = "gpt-5.1"
approval_policy = "on-request"      # 需要时再询问是否执行
sandbox_mode = "workspace-write"    # 允许在当前工程写文件，依旧禁网

# 临时设置，切换窗口后失效
set V_API_KEY=sk-xxxxxx

# 永久设置
setx V_API_KEY "sk-xxxxxx"

# 如果使用 bash
nano ~/.bash_profile
# 或
nano ~/.bashrc

# 如果使用 zsh（Mac默认）
nano ~/.zshrc

export V_API_KEY="sk-xxxxxx"

# bash
source ~/.bash_profile

# zsh
source ~/.zshrc

export V_API_KEY="sk-xxxxxx"

# Windows (CMD)
echo %V_API_KEY%

# Windows (PowerShell)
echo $env:V_API_KEY

# Mac/Linux
echo $V_API_KEY

# 直接提问
codex "你好"

# 选择提供商并提问(如果有多个提供商的话)
codex --profile vapi "你好"
