# Codex

Codex CLI 使用 OpenAI Responses。Base URL 保留 `/v1`，API Key 放在 `LMM_API_KEY`。

| 配置项 | 值 |
| - | - |
| Base URL | `https://api.lmm.best/v1` |
| API Key | `LMM_API_KEY` |
| 协议 | `wire_api = "responses"` |

编辑 `~/.codex/config.toml`：

```toml theme={null}
model = "gpt-5.6-sol"
model_provider = "lmm"

[model_providers.lmm]
name = "LMM API"
base_url = "https://api.lmm.best/v1"
wire_api = "responses"
env_key = "LMM_API_KEY"
```

<CodeGroup>
  ```bash macOS / Linux theme={null}
  export LMM_API_KEY=sk-xxxxxxxx
  codex
  ```

  ```powershell Windows PowerShell theme={null}
  $env:LMM_API_KEY="sk-xxxxxxxx"
  codex
  ```
</CodeGroup>

`model` 换成控制台 **模型与价格** 里可用的模型 ID。
