Validate and Use

1

Validate credentials

Click Validate in the OpenAI credential settings. If validation fails, confirm the key is active and billing is enabled in the OpenAI Platform dashboard.
2

Refresh models

Reopen the model dropdown after validation. EnConvo loads available OpenAI models from your account and falls back to defaults when the model API cannot be reached.
3

Send a short test

Use a simple prompt such as Say hello in one sentence before running long chats, agents, or automation workflows.
OpenAI API billing is separate from a ChatGPT Plus or Pro subscription. Use the OpenAI subscription provider if you want to connect an existing ChatGPT plan instead.

​
o1, o3, o4 Series
