Parameter resolution in sub-nodes

Sub-nodes behave differently to other nodes when processing multiple items using an expression.

Most nodes, including root nodes, take any number of items as input, process these items, and output the results. You can use expressions to refer to input items, and the node resolves the expression for each item in turn. For example, given an input of five `name` values, the expression `{{ $json.name }}` resolves to each name in turn.

In sub-nodes, the expression always resolves to the first item. For example, given an input of five `name` values, the expression `{{ $json.name }}` always resolves to the first name.

## Node parameters

### Model

Select the model to use to generate the completion.

n8n dynamically loads models from OpenRouter and you'll only see the models available to your account.

## Node options

Use these options to further refine the node's behavior.

### Frequency Penalty

Use this option to control the chances of the model repeating itself. Higher values reduce the chance of the model repeating itself.

### Maximum Number of Tokens

Enter the maximum number of tokens used, which sets the completion length.

### Response Format

Choose **Text** or **JSON**. **JSON** ensures the model returns valid JSON.

### Presence Penalty

Use this option to control the chances of the model talking about new topics. Higher values increase the chance of the model talking about new topics.

### Sampling Temperature

Use this option to control the randomness of the sampling process. A higher temperature creates more diverse sampling, but increases the risk of hallucinations.

### Timeout

Enter the maximum request time in milliseconds.

### Max Retries

Enter the maximum number of times to retry a request.

### Top P

Use this option to set the probability the completion should use. Use a lower value to ignore less probable options.
