Embeddings OpenAI#

Use the Embeddings OpenAI node to generate embeddings for a given text.

On this page, you'll find the node parameters for the Embeddings OpenAI node, and links to more resources.


You can find authentication information for this node here.

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 options#

  • Model: The model to use for generating embeddings.
  • Base URL: the URL to send the request to. Use this if you are using a self-hosted OpenAI-like model.
  • Batch Size: maximum number of documents to send in each request.
  • Strip New Lines: whether to remove new line characters from input text. n8n enables this by default.
  • Timeout: maximum amount of time a request can take in seconds. Set to -1 for no timeout.
