You can now use a Roboflow-managed OpenAI API Key in your Workflows.

When you use the Roboflow-managed key, you will be billed based on usage according to our [Credits-based billing](https://roboflow.com/credits).

To use a Roboflow-managed key, set the "Api Key" field in a OpenAI Workflow block to "Roboflow Managed API Key".
