In the Instructions tab, scroll down to the AI Model section.
Click the link for your provider under the Model authentication field. A new window or tab will open.
- Click Add connection.
- Paste your API key in the field provided.

Once you select a connection, the Model dropdown menu will display the models available for your account. The model selection may not reflect what you see on your OpenAI account, as not all models are available through an API.
