The Default Node is the most versatile component in Agent Graphs, handling general conversation flow and complex reasoning.

​
Purpose & Functionality

The Default Node uses the configured LLM to interpret its specific prompt within the conversation’s context. How it interacts (notification vs. pausing for input) depends entirely on the instructions within its prompt.

​
Use Cases

  • General conversation steps
  • Asking questions
  • Providing information
  • Complex reasoning
  • Decision-making

​
Configuration

  • Name: A label for the node on the Canvas
  • Prompt: Instructions for the agent at this step

​
Examples

Example 1: Non-pausing notification

Send a message to the customer thanking them for their purchase and confirming 
their order has been received.

Example 2: Pausing to collect information

Ask the customer what size t-shirt they would like to order. Make sure to 
list the available sizes (S, M, L, XL).
