Built-in models
Enable an available built-in model on this page, then select it at the top of a chat. Its use counts against your account quota; view the remaining amount and trend in Account and billing.Custom models
To use your own provider or gateway, add a custom model with the information supplied by that provider:- model ID;
- API key;
- API endpoint;
- context-window size; and
- API protocol.
Choose a protocol
Use the provider’s documented protocol. If you are unsure which option applies, choose Chat first. Verify the model with a simple conversation before using it for a larger writing task.Tips
- A model must be enabled before it appears in the chat selector.
- Check the configured endpoint, key, and model ID when a custom model cannot be used.
- Changing the available models does not interrupt a reply that is already running.
