Use OpenRouter LLMs in n8n <1.78 via OpenAI Node

This workflow provides a simple yet effective workaround for n8n users on versions prior to 1.78 to integrate OpenRouter, a service offering access to numerous LLM models from various providers. By configuring the OpenAI node with OpenRouter's specific base URL (https://openrouter.ai/api/v1), you can dynamically use any model from OpenRouter's extensive list without needing the native OpenRouter node introduced later. Key benefits include flexibility in model selection—change models on the fly
