+
+This module separates **AI chat and AI Agent authentication** from the
+credentials used by supporting OpenAI API services in Odoo Enterprise
+AI.
+
+It allows organizations to route AI conversational queries, chat bots,
+and AI fields through an eligible **ChatGPT subscription** (Plus, Pro,
+Team, Enterprise) via an OAuth 2.0 Device Code grant flow, eliminating
+per-token generation costs for interactive chat while preserving the
+standard OpenAI developer API key for knowledge embeddings, Whisper
+voice transcription, and realtime sessions.
+
+Supported configurations:
+
+- **OpenAI API key only**: Standard Odoo setup (pay-per-token API for
+  chat, embeddings, and voice).
+- **ChatGPT subscription only**: ChatGPT subscription for chat and
+  agents. Knowledge embeddings and voice remain unconfigured.
+- **Mixed / Hybrid**: ChatGPT subscription for chat and agents; OpenAI
+  developer API key for embeddings and voice.

+
+Configuration
+=============
+
+To configure this module:
+
+1. Navigate to **AI > Configuration > Settings** (or **General Settings
+   > AI Providers**) as a Settings Administrator
+   (``base.group_system``).
+2. Under **Use your own ChatGPT / OpenAI account**, choose **ChatGPT
+   Subscription (OAuth)** under Connection Type.
+3. Click **Connect ChatGPT Subscription** to launch the device
+   authentication wizard.
+4. Follow the prompt to visit ``https://auth.openai.com/codex/device``
+   and input the provided one-time code to authorize the Odoo instance.
+5. Return to Odoo and click **Verify & Connect**.
+6. (Optional) In the same section, expand the optional API key section
+   to provide a developer API key if knowledge base embeddings (RAG) or
+   voice transcription are also needed.
+7. Use the **Sync Models** and **Test Connection** buttons to verify
+   credentials and synchronize available models.
+
+Usage
+=====
+
+Once configured:
+
+1. Open any **AI Agent** record under **AI > Agents**.
+2. Select any active ChatGPT model directly from the **LLM Model**
+   dropdown (e.g. ``GPT-5.6 Luna``, ``GPT-5.6 Terra``, ``GPT-5.5``,
+   ``GPT-5.4``, etc.).
+3. Conversations initiated with the AI agent or chat bots will
+   automatically stream responses through the authorized ChatGPT
+   subscription without per-token charges.
+4. Tokens are automatically refreshed every 2 hours via a background
+   cron job (``ir.cron``), with concurrency protection across
+   multi-worker environments.
+
+Managing & Adding New Models
+----------------------------
+
+When OpenAI releases new models or deprecates older versions:
+
+1. Navigate to **AI > Configuration > Settings**.
+2. Under the connected ChatGPT section, click **Manage Models**.
+3. To add a newly released OpenAI model (e.g., ``GPT-5.7 Pro`` with
+   technical code ``gpt-5.7-pro``), click **New** and enter the display
+   name and technical model ID.
+4. To deactivate an old or deprecated model, simply toggle its
+   **Active** switch off.
+5. The model selection on all AI Agents will update immediately across
+   Odoo.
