# Gemini in Java with Vertex AI and LangChain4j


- **Date:** Wednesday, Jul 17, 2024
- **Time:** 16:15–18:15 (120 min)
- **Room:** Workshop room M6 (40)
- **Event:** World Congress 2024

## Description

This codelab focuses on the Gemini Large Language Model (LLM), hosted on Vertex AI on Google Cloud. Vertex AI is a platform that encompasses all the machine learning products, services, and models on Google Cloud.

You will use Java to interact with the Gemini API using the LangChain4j framework. You'll go through concrete examples to take advantage of the LLM for question answering, idea generation, entity and structured content extraction, retrieval augmented generation, and function calling.

For this workshop session, you will need a laptop with Google Chrome installed and ensure you have access to a personal Google account.
