Use loops when you need to rerun a node or part of the flow multiple times. Example of an Agent with loops The above example shows a simple agent that would identify the landmark in the given image and return the current weather of that location. The flow that occurs is as follows:
  1. The Prompt node gets the initial image as an input and runs the LLM to identify the landmark.
  2. The getWeather tool is called with the location of the landmark as input.
  3. The output of the getWeather tool is connected back to the Prompt node.
  4. The Prompt node runs again with the updated context and returns an assistant message to move the agent forward.
  5. The Final output node gets executed and the agent completes its execution.
