### ChatGPT subscription login (OpenAI)

Run `clawcodex login`, choose `openai`, then choose `subscription`. Three
login methods are offered: `browser` (opens ChatGPT's PKCE authorization page
and completes via a localhost:1455 redirect — the same flow the Codex CLI
uses), `device-code` (for headless/SSH machines: enter a short code at
auth.openai.com/codex/device), and `import-codex-cli` (shown when a Codex CLI
ChatGPT login exists in `~/.codex/auth.json` — copies it). Tokens are stored
in `~/.clawcodex/openai-oauth.json` with user-only permissions and refresh
automatically. With a subscription connected and no OpenAI API key set,
requests go to the ChatGPT Codex backend (Responses API) and draw on your
plan's allowance — the cost display shows $0. An explicit `OPENAI_API_KEY` or
configured OpenAI API key takes precedence. Subscription models:
`gpt-5.5`, `gpt-5.4`, `gpt-5.4-mini`, `gpt-5.3-codex-spark`.

> **Important:** using a ChatGPT plan from third-party clients rides the
> Codex CLI's official OAuth app, remains subject to OpenAI's terms, and may
> stop working. The login flow requires explicit confirmation.

Use `clawcodex config` to check connection status and
`clawcodex logout openai` to delete the stored OAuth credentials.
