Compare LLM Responses Side-by-Side with Google Sheets
Compare outputs from two LLMs in a chat interface side-by-side, while logging responses, prompts, and context to Google Sheets for easy evaluation.
This n8n workflow enables seamless side-by-side comparison of responses from two different language models (LLMs) directly in a chat interface. User inputs are duplicated and routed to separate AI Agent nodes, each configured with its own model (e.g., via OpenRouter, Vertex AI, or OpenAI), system prompts, tools, and memory context. Responses are then displayed sequentially in the chat for immediate visual comparison, allowing quick assessment of quality, consistency, and relevance.
