Goal
Use multiple AI agents (e.g., Gemini and ChatGPT) to analyze the same input and cross-validate results for higher accuracy and reliability.
🛠️ Step 1: Create a New Workflow
- Log in to n8n.io.
- Click “Create Workflow”.
- Name it something like
Multi-Agent Validator.
📥 Step 2: Add a Trigger Node
- Use a Form Trigger or Webhook Trigger to start the workflow.
- Example: Upload a receipt, invoice, or PDF file.
🧠 Step 3: Add First AI Agent Node (Gemini)
- Add a Google Gemini Node.
- Configure:
- Model: Gemini 2.5 Pro
- Prompt:
"Extract structured data from this document." - Input: Connect to the uploaded file.
🧠 Step 4: Add Second AI Agent Node (ChatGPT)
- Add an OpenAI Node.
- Configure:
- Model: GPT-4 or GPT-3.5
- Prompt: Same or slightly different from Gemini’s.
- Input: Same uploaded file.
🔍 Step 5: Add Comparison Node
- Use a Function Node or Set Node to compare outputs from both agents.
- Logic:
- Highlight differences.
- Flag inconsistencies.
- Optionally, choose the more confident result.
📤 Step 6: Output or Store Results
- Add a Google Sheets, Excel, or Database Node.
- Store:
- Gemini result
- ChatGPT result
- Final validated result
🧪 Optional Enhancements
- Add a third agent (e.g., Mistral or Claude) for deeper validation.
- Use confidence scoring if supported by the model.
- Add error handling and retry logic.
