The transition from a compelling ChatGPT prompt to a scalable, production-ready product is the defining challenge for today's innovators. Join us to explore a real-world journey of transforming an idea tested in a chat window into a robust, deployed Flask API complete with OpenAPI documentation. In this session, we'll dive deep into the technical and strategic decisions necessary to support Product-Led Growth (PLG). You'll learn how to design AI-Powered APIs that intelligently blend Large Language Model (LLM) flexibility with deterministic, auditable business logic. We'll demystify the process of building and orchestrating automated AI workflows using n8n alongside models like ChatGPT and Claude to automate critical functions, such as cross-platform publishing. Finally, we'll share practical, hard-won lessons on maintaining quality and efficiency in production. This includes setting up automated evals for accuracy, managing model drift, implementing crucial cost controls, and ensuring API governance for rapid, reliable shipping. Walk away with the blueprint for creating AI APIs that not only work but create tangible, measurable business value.
