三大平台都可以使用 npm 一键安装： npm install -g @openai/codex

打开 ~/.codex/config.toml，文件不存在则创建，并写入以下内容（将 你的在问APIKEY 替换为实际 Key）：

toml

model_provider = "custom"
model = "gpt-5.6-luna"
model_reasoning_effort = "medium"
disable_response_storage = true

[model_providers.custom]
name = "custom"
base_url = "https://oneapi.zaiwenai.com/v1"
wire_api = "responses"
requires_openai_auth = false
http_headers = { "x-openai-actor-authorization" = "local-image-extension" }
experimental_bearer_token = "你的在问APIKEY"

也可以使用以下辅助命令自动备份并写入。macOS、Linux 或 WSL：

bash

mkdir -p "$HOME/.codex"
[ ! -f "$HOME/.codex/config.toml" ] || cp "$HOME/.codex/config.toml" "$HOME/.codex/config.toml.bak"
cat > "$HOME/.codex/config.toml" << 'CODEX_EOF'
model_provider = "custom"
model = "gpt-5.6-luna"
model_reasoning_effort = "medium"
disable_response_storage = true

[model_providers.custom]
name = "custom"
base_url = "https://oneapi.zaiwenai.com/v1"
wire_api = "responses"
requires_openai_auth = false
http_headers = { "x-openai-actor-authorization" = "local-image-extension" }
experimental_bearer_token = "你的在问APIKEY"
CODEX_EOF

Windows PowerShell：

powershell

$codexDir = Join-Path $HOME ".codex"
$configPath = Join-Path $codexDir "config.toml"
New-Item -ItemType Directory -Force -Path $codexDir | Out-Null
if (Test-Path $configPath) { Copy-Item $configPath "$configPath.bak" -Force }
@'
model_provider = "custom"
model = "gpt-5.6-luna"
model_reasoning_effort = "medium"
disable_response_storage = true

[model_providers.custom]
name = "custom"
base_url = "https://oneapi.zaiwenai.com/v1"
wire_api = "responses"
requires_openai_auth = false
http_headers = { "x-openai-actor-authorization" = "local-image-extension" }
experimental_bearer_token = "你的在问APIKEY"
'@ | Set-Content -Encoding utf8 $configPath

配置说明

model：默认使用 gpt-5.6-luna，也可以替换为在问 OneAPI 支持的其他 Codex 系列模型
requires_openai_auth = false + experimental_bearer_token：将 API Key 直写于 config.toml 的 provider 配置中，无需再维护 ~/.codex/auth.json；experimental_bearer_token 与 env_key / requires_openai_auth / [model_providers.*.auth] 互斥
wire_api = "responses"：走 OpenAI Responses 协议（/v1/responses），与在问服务端一致，能正确下发 reasoning.effort
http_headers：激活 Codex 客户端本地图片工具（image_gen，Responses Lite）；该 header 透传到服务端，在问服务端忽略未知 header，无副作用；改完需完全重启 Codex 并开新会话重建工具列表
辅助命令会在覆盖前将已有配置文件备份为 ~/.codex/config.toml.bak
旧版 ~/.codex/auth.json（OPENAI_API_KEY）已废弃，如仍存在可手动删除
