When a chat message is received, it gets processed through a basic LLM chain and returns a response.\n\n## Components\n- **Trigger Node**\n- **Processing Node**\n- **Model Node**\n- **JSON to Object Node**\n- **Structured Response Node**\n- **Error Response Node**\n\n## Workflow Structure\n1. The chat trigger node receives incoming messages\n2. Messages are passed to the Basic LLM Chain\n3. The Ollama Model processes the input using Llama 3.2\n4. Responses are returned through the chain\n\n## Prerequisites\n- N8N installation\n- Ollama setup with Llama 3.2 model\n- Valid Ollama API credentials\n\n## Configuration\n1. Set up the Ollama API credentials in N8N\n2. Ensure the Llama 3.2 model is available in your Ollama installation\n\n"}, "typeVersion": 1, "notes": "This stickyNote node performs automated tasks as part of the workflow."}, {"id": "64f60ee1-7870-461e-8fac-994c9c08b3f9", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [340, 280], "parameters": {"width": 560, "height": 200, "content": "## Model Node\n- Name: Ollama Model\n- Type: LangChain Ollama Integration\n- Model: llama3.2:latest\n- Purpose: Provides the language model capabilities"}, "typeVersion": 1, "notes": "This stickyNote node performs automated tasks as part of the workflow."}, {"id": "bb46210d-450c-405b-a451-42458b3af4ae", "name": "Sticky Note2", "type": "n8n-nodes-base.stickyNote", "position": [200, -160], "parameters": {"color": 6, "width": 280, "height": 400, "content": "## Trigger Node\n- Name: When chat message received\n- Type: Chat Trigger\n- Purpose: Initiates the workflow when a new chat message arrives"}, "typeVersion": 1, "notes": "This stickyNote node performs automated tasks as part of the workflow."}, {"id": "7f21b9e6-6831-4117-a2e2-9c9fb6edc492", "name": "Sticky Note3", "type": "n8n-nodes-base.stickyNote", "position": [520, -380], "parameters": {"color": 3, "width": 500, "height": 620, "content": "## Processing Node\n- Name: Basic LLM Chain\n- Type: LangChain LLM Chain\n- Purpose: Handles the processing of messages through the language model and returns a structured JSON object.\n\n"}, "typeVersion": 1, "notes": "This stickyNote node performs automated tasks as part of the workflow."}, {"id": "871bac4e-002f-4a1d-b3f9-0b7d309db709", "name": "Sticky Note4", "type": "n8n-nodes-base.stickyNote", "position": [560, -200], "parameters": {"color": 7, "width": 420, "height": 200, "content": "### Prompt (Change this for your use case)\nProvide the users prompt and response as a JSON object with two fields:\n- Prompt\n- Response\n\n\nAvoid any preample or further explanation.\nThis is the question: {{ $json.chatInput }}"}, "typeVersion": 1, "notes": "This stickyNote node performs automated tasks as part of the workflow."}, {"id": "c9e1b2af-059b-4330-a194-45ae0161aa1c", "name": "Sticky Note5", "type": "n8n-nodes-base.stickyNote", "position": [1060, -280], "parameters": {"color": 5, "width": 420, "height": 520, "content": "## JSON to Object Node\n- Type: Set Node\n- Purpose: A node designed to transform and structure response data in a specific format before sending it through the workflow.
