The Set System Prompt node is a fundamental component for configuring how your AI models behave. This guide explains how to use system prompts effectively in your Neurons.

​
Functionality

The Set System Prompt node allows you to define or modify the System Prompt for a Neuron.

The last Set System Prompt node set in your workflow is the prompt that LLM will use.

​
Node Properties

  • System Prompt:
    • The system prompt to be used for the LLM.
  • Prompt Position: Select how you want the prompt to behave:
    • Insert Text Before Existing System Prompt: Add text at the start of any existing system prompt. This can allow you to inject a short introductory statement, or additional instructions.
    • Insert Text After Existing System Prompt: Add text to the end of the existing system prompt. This position could be useful for providing clarifying information or examples.
    • Replace Entire System Prompt: Overwrite the entire system prompt with a new text, effectively resetting the LLM’s context.

​
Usage Examples

​
Scenario: Defining an AI assistant

In a customer support chatbot neuron, you might use a Set System Prompt with a prompt that reads:

You are a helpful and concise AI customer support assistant. Your goal is to answer customer questions politely and effectively.

Tips and Best Practices

  • Using a Randomized Split node before the system prompt node can help you test different prompts with the same input — this can help you refine your prompt over time and roll out changes in a controlled manner.
  • Think carefully about how you want to configure the prompt. Overwriting, adding before, or adding after can have significant effects on the output’s response.
  • Test your system prompt changes with different inputs to ensure the LLM responds appropriately in various scenarios.
  • Keep your system prompts clear and concise to avoid confusion or conflicting instructions.
