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 {{ $ }} 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 {{ $ }} always resolves to the first name.

Node parameters#

Model: the model to use to generate the completion. n8n dynamically loads models from the Google PaLM API and you will only see the models available to your account.

Node options#

  • Sampling Temperature: controls the randomness of the sampling process. A higher temperature creates more diverse sampling, but increases the risk of hallucinations.
  • Top K: the number of token choices the model uses to generate the next token.
  • Top P: use a lower value to ignore less probable options.
