When a chat message is received, it gets processed through a basic LLM chain and returns a response.nn## Componentsn- **Trigger Node**n- **Processing Node**n- **Model Node**n- **JSON to Object Node**n- **Structured Response Node**n- **Error Response Node**nn## Workflow Structuren1. The chat trigger node receives incoming messagesn2. Messages are passed to the Basic LLM Chainn3. The Ollama Model processes the input using Llama 3.2n4. Responses are returned through the chainnn## Prerequisitesn- N8N installationn- Ollama setup with Llama 3.2 modeln- Valid Ollama API credentialsnn## Configurationn1. Set up the Ollama API credentials in N8Nn2. Ensure the Llama 3.2 model is available in your Ollama installationnn"
