Demystifying GenAI: Building a ChatGPT App with Vector Store

With ChatGPT taking center stage since the beginning of 2023, developers who have not had a chance to work with any forms of Artificial Intelligence or Machine Learning systems may find themselves either intrigued by the “maze” of new terminologies, or some may be eager to learn more, while perhaps a smaller group may not actually want to get themselves into a territory that’s unknown to them.

This workshop is catered for Java developers as we start by having a quick introduction to GenAI, ChatGPT, and all of those new terminologies around generative AI. Then we’ll dive right into the hands-on part, about how we can construct a ChatGPT-based app quickly, using state-of-the-art tools such as PgVector, which provides vector extension to the popular open source Postgres.

Hands-on lab will cover:

  • Vector Search with PgVector
  • LLM providers and APIs using Langchain4j
  • Integrating with ChatGPT models
  • Generating embeddings
  • Prompt engineering
  • Building generative AI applications
