OpenAI Assistant Demo with Custom Tool Calling

This n8n template is a hands-on demonstration of how to extend an OpenAI Assistant with custom tools inside n8n, one that calls a sub-workflow to answer questions and another that fetches the current date and time. It is built as a learning template for developers who want to understand tool-calling patterns before building their own production assistants, showing exactly how to wire an OpenAI Assistant to n8n sub-workflows and code tools. A great starting point for anyone prototyping AI agents that need to trigger real actions rather than just generate text.
