</Info>
<Tip>
The Codex models (e.g., `gpt-5.3-codex`) are optimized for code and reasoning tasks — ideal for complex browser automation workflows that involve form filling, data extraction, and multi-step navigation.
</Tip>
## Reasoning Settings
ChatGPT Pro includes additional settings for models that support reasoning:
- **Reasoning Effort** — Control how much the model "thinks" before responding. Options: none, low, medium, high.
- **Reasoning Summary** — Choose how reasoning is displayed. Options: auto, concise, detailed.
These settings are available in the provider configuration after connecting.
## Disconnecting
To disconnect your OpenAI account, go to **Settings**, find the ChatGPT Plus/Pro provider, and click **Disconnect**. Your OAuth tokens will be immediately deleted from your machine.
