This workflow demonstrates how to utilize OpenRouter in n8n versions before 1.78, allowing users to dynamically select and configure different LLM models. By setting up OpenAI nodes with OpenRouter-specific BaseURL, you can switch between models based on external configurations, rules, or chat messages. This setup is ideal for users who need flexibility in their LLM model selection and configuration within n8n workflows.
