Codex APP 正常使用环节需要科学上网环境，需注意

AveMujicaAPI 注册

1. 通过我个人的邀请链接https://api.avemujica.moe/sign-up?aff=3X69 注册API，aff邀请链接无明确收益，仅作统计😋
2. 通过控制台平台-个人-钱包-进行氪金
   
   
3. 在API密钥条目中，右上角点击创建API密钥，键入任意名称，分组选为default，并将APIkey保存下来，注意不要泄露自己的key，防止其他人盗用
   
   

codex 安装

1. 在windows环境下，复制以下代码在 PowerShell 中运行，脚本会安装 Codex CLI，备份已有 .codex\config.toml 和 .codex\auth.json，再写入 AveMujicaAPI provider。PowerShell可通过win+x，选择终端管理员或powershell管理员模式启动，脚本运行过程中需要填入一次前文所要求保留的APIkey

    $SecureKey = Read-Host "AveMujicaAPI API Key" -AsSecureString
    $Bstr = [Runtime.InteropServices.Marshal]::SecureStringToBSTR($SecureKey)
    $ApiKey = [Runtime.InteropServices.Marshal]::PtrToStringBSTR($Bstr)
    [Runtime.InteropServices.Marshal]::ZeroFreeBSTR($Bstr)
    
    $Model = Read-Host "Model ID [gpt-5.5]"
    if ([string]::IsNullOrWhiteSpace($Model)) {
      $Model = "gpt-5.5"
    }
    
    if ([string]::IsNullOrWhiteSpace($ApiKey)) {
      throw "API Key is required."
    }
    
    npm install -g @openai/codex
    
    $CodexDir = Join-Path $env:USERPROFILE ".codex"
    New-Item -ItemType Directory -Force -Path $CodexDir | Out-Null
    
    $Stamp = Get-Date -Format "yyyyMMddHHmmss"
    $ConfigPath = Join-Path $CodexDir "config.toml"
    $AuthPath = Join-Path $CodexDir "auth.json"
    
    if (Test-Path $ConfigPath) {
      Copy-Item $ConfigPath "$ConfigPath.bak.$Stamp"
    }
    if (Test-Path $AuthPath) {
      Copy-Item $AuthPath "$AuthPath.bak.$Stamp"
    }
    
    @"
    model_provider = "avemujicaapi"
    model = "$Model"
    model_reasoning_effort = "xhigh"
    disable_response_storage = true
    
    [model_providers.avemujicaapi]
    name = "AveMujicaAPI"
    base_url = "https://api.avemujica.moe/v1"
    requires_openai_auth = true
    stream_idle_timeout_ms = 600000
    wire_api = "responses"
    "@ | Set-Content -Encoding UTF8 $ConfigPath
    
    @{ OPENAI_API_KEY = $ApiKey } | ConvertTo-Json | Set-Content -Encoding UTF8 $AuthPath
    
    codex --version
   

   
   
   2. 安装codex app，下载链接。安装后，通过之前的步骤要求的apikey登录即可开始正常使用。
