+# OpenAI
+
+This documentation covers two authentication approaches for OpenAI access within the Codex platform.
+
+## Authentication Options
+
+**API Key Method**: Users can configure direct API access through OpenAI's platform using usage-based billing. Setup requires obtaining credentials from the OpenAI dashboard and running the onboarding wizard with the appropriate flag.
+
+**ChatGPT Subscription Method**: An alternative approach leverages existing ChatGPT or Codex subscriptions rather than direct API credentials. This method requires OAuth authentication through the Codex CLI or cloud interface.
+
+## Configuration Details
+
+Both approaches require specifying a model reference in the format `provider/model`. Model refs always use `provider/model`.
+
+## Setup Process
+
+The onboarding CLI accepts either direct API key input or interactive authentication selection. Users can bypass the interactive wizard by providing credentials as command-line arguments during setup.
+
+```bash
+openclaw onboard --auth-choice openai-api-key
+```
+
+Or with the API key directly:
+
+```bash
+openclaw onboard --openai-api-key "$OPENAI_API_KEY"
+```
+
+## Config snippet
+
+```json5
+{
+  env: { OPENAI_API_KEY: "sk-..." },
+  agents: { defaults: { model: { primary: "openai/gpt-4o" } } },
+}
+```
