Pydantic: Too young to learn C, too old to learn Rust, just in time for LLMs

Pydantic Python llms prompt engineering parsing responses robust function calling tool chaining via apis

Description

When working with Large Language Models (LLMs), how do we ensure a probabilistic blob of text is something our code can actually use? In this talk, we explore how Pydantic emerged at a perfect moment exactly for this task; bridging Python's flexibility with the structured data needs of modern AI applications. We will introduce Pydantic and then demonstrate practical applications of it; from prompt engineering and parsing responses, to example of robust function calling and tool chaining via APIs.
