## Model Settings

Each Model node lets you configure:

| Setting         | Description                                  |
| --------------- | -------------------------------------------- |
| **Model**       | Which AI model to use                        |
| **Temperature** | Creativity level (0 = precise, 1 = creative) |

## Credits

Each workflow execution costs **1 credit**, regardless of which model is used.

> **Note:** Actual API costs when using BYOK depend on the model provider's pricing.

***

> **Pro tip:** Start with a cheaper model to test your workflow, then switch to a more powerful one when you're happy with the design.
