## Node parameters

* **Model**: Select the model to use to generate the completion.

## Node options

* **Frequency Penalty**: Use this option to control the chances of the model repeating itself. Higher values reduce the chance of the model repeating itself.
* **Maximum Number of Tokens**: Enter the maximum number of tokens used, which sets the completion length.
* **Response Format**: Choose **Text** or **JSON**. **JSON** ensures the model returns valid JSON.
* **Presence Penalty**: Use this option to control the chances of the model talking about new topics. Higher values increase the chance of the model talking about new topics.
* **Sampling Temperature**: Use this option to control the randomness of the sampling process. A higher temperature creates more diverse sampling, but increases the risk of hallucinations.
* **Timeout**: Enter the maximum request time in milliseconds.
* **Max Retries**: Enter the maximum number of times to retry a request.
* **Top P**: Use this option to set the probability the completion should use. Use a lower value to ignore less probable options. 

## Proxy limitations

This node doesn't support the [`NO_PROXY` environment variable](/hosting/configuration/environment-variables/deployment.md).
