Chapter 3. AI Integration and Model Serving
In this chapter, you will learn the mechanisms of various GenAI models and how to serve them in a FastAPI application. Additionally, using the Streamlit UI package, you will create a simple browser client for interacting with the model-serving endpoints. We will explore differing model-serving strategies, how to preload models for efficiency, and how to use FastAPI features for service monitoring.
To solidify your learning in this chapter, we will progressively build a FastAPI service using open source GenAI models that generate text, images, audio, and 3D geometries, all from scratch. In later chapters, you’ll build the functionality to parse documents and web content for your GenAI service so you can talk to them using a language model.
