What is an Input Node?

Output node
An Input node allows you and your end-users to send text messages to any node that accepts text strings as input. The most popular nodes accepting inputs are:
  1. The LLM nodes (adding the input as part of their prompt).
  2. The Knowledge Base nodes (they use the input as a prompt to retrieve information from their contents)
Here are a few quick facts:
  • The inputs can be text fields of any length and are passed to their connected node in the flow.
  • While inputs can be of any length, you should be mindful that LLM prompts have a limit on how long of an input they can process. To handle long inputs, consider using the Text Data Loader.
  • To expose an Input node to your users, you will need to set it up in the Export tab.
