From Zero to Hero: How to put GPT LLMs & Friends into your Applications

Unlocking the power of human language as the universal interface for software solutions—sounds intriguing, right? In this masterclass, Christian and Sebastian dive into integrating Generative AI and Large Language Models (LLMs) into your applications.

With a focus on Python APIs, we’ll guide you in leveraging the capabilities of both OpenAI GPT and open-source models across a variety of use cases. The course centers on key architectural patterns such as In-Context Learning, Retrieval-Augmented Generation (RAG), Structured Output, Tool Calling, and Reasoning & Acting (ReAct). These techniques are essential for building cutting-edge, AI-enhanced business applications. Let’s explore practical approaches and end-to-end methods for integrating Generative AI into your business applications.
