 OpenAI `reasoningEffort` supports `'none'`, `'minimal'`, `'low'`, `'medium'`, `'high'`, and `'xhigh'`. Model IDs are accepted as strings, so new IDs like `'gpt-5.5'` can be used before upstream model unions are updated.

-SmartAI can request ChatGPT subscription-backed Codex credentials with OpenAI's device-code flow. The returned credentials are passed to `getModel()` through `openAiMaxAuth`; SmartAI then routes OpenAI model calls through the ChatGPT Codex backend with the required account headers.

+Node.js consumers can inspect and resolve local ChatGPT auth files through the Node-only subpath. This supports SmartAI's canonical auth file, OpenCode's `~/.local/share/opencode/auth.json`, and Codex's `~/.codex/auth.json` without exposing token values in inspection results.
