# LLM Node Configuration

LLM (Language Model) nodes are the core of Automateo's functionality. Here's how to configure them:

1. **Prompt Templates**
   * Use "{variable}" syntax to reference outputs from previous nodes
   * Example: "Summarize the following text: {input\_text}"
2. **Model Selection**
   * Choose from various LLM models:
     * ChatGPT 3
     * ChatGPT 4
     * Mixtral
     * LLaMA
     * (Other available models)
3. **Output Format**
   * Specify the desired output format:
     * Text: For general text output
     * Markdown: For formatted text
     * JSON schema: For structured data output

Remember to test your LLM nodes with sample inputs to ensure they produce the expected outputs before integrating them into your production workflows.
