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 embedding.
n8n dynamically loads models from the Google PaLM API and you'll only see the models available to your account.

- completion: Completions are the responses generated by a model like GPT.
- hallucinations: Hallucination in AI is when an LLM (large language model) mistakenly perceives patterns or objects that don't exist.
- vector database: A vector database stores mathematical representations of information. Use with embeddings and retrievers to create a database that your AI can access when answering questions.
