Custom Models

Dyad lets you use any AI model or provider, as long as they offer an OpenAI-compatible API.

Add a provider

Go to Settings, find the AI Providers section, and click Add Custom Provider. This will open a dialog where you can fill in the required information:

• ID: This is used internally and cannot be changed later. You can choose any value.
• Display Name: This is what will appear in the Dyad UI.

You can usually find the API Base URL in the provider’s documentation.

Add a model

In the AI Providers section of Settings, click on the provider you want to add a model for. On the provider’s page, scroll to the bottom and click Add Custom Model.

Fill in the following:

• Model ID: This must match exactly what's specified in the provider’s API documentation. It’s the identifier sent to the API.
• Name: A user-friendly label shown in the Dyad UI.
• Description: Optional information displayed in a tooltip—e.g., noting if the model is free.
• Max Output Tokens and Context Window: Set these based on the provider’s documentation. If left blank, Dyad will use default values, which may be smaller than optimal.
