As the author of auto-cpufreq, a popular open-source Linux utility that automatically optimizes CPU speed and power usage, I was facing daily support requests. To help alleviate this, I built a chatbot using Vertex AI Agent Builder and Gemini. This chatbot automates answers to common user questions about installation, configuration, and troubleshooting. It uses a diverse dataset including GitHub issues, YouTube videos, my own Reddit comments, blog posts, the project README, and more, allowing it to provide instant support. In this talk, I'll demonstrate how the chatbot works, and dive into the development process.

Can you build a Node.js web app without writing code? In this live coding session, Esther explores the practical capabilities of Gemini Code Assist, attempting to build and deploy a functional application on Google Cloud using only prompts. Expect her to get real about what's possible (and what's not) with AI-driven development, showcasing both the potential and the current limitations. This session is perfect for developers of all levels interested in AI-assisted coding and the future of software.

This talk introduces Retrieval-Augmented Generation (RAG), a technique that grounds Large Language Model (LLM) responses in retrieved data to enhance accuracy and relevance. Through practical examples with LangChain4j in Java, the session covers RAG fundamentals, including architecture, implementation, and basic chunking. It then progresses to advanced techniques: sophisticated chunking, query compression, routing, metadata filtering, content aggregation, and re-ranking.

Breakout session 1: Beyond the prompt: evaluating, testing, and securing LLM applications

When you change prompts or modify the Retrieval-Augmented Generation (RAG) pipeline in your LLM applications, how do you know it's making a difference? You don't—until you measure. But what should you measure, and how? Similarly, how can you ensure your LLM app is resilient against prompt injections or avoids providing harmful responses? More robust guardrails on inputs and outputs are needed beyond basic safety settings.

In this talk, we'll explore various evaluation frameworks such as Vertex AI Evaluation, DeepEval, and Promptfoo to assess LLM outputs, understand the types of metrics they offer, and how these metrics are useful. We'll also dive into testing and security frameworks like LLM Guard to ensure your LLM apps are safe and limited to precisely what you need.

Workshop 1: Gemini with Vertex AI and LangChain

This hands-on workshop gets you building with Gemini in Java or Python. You’ll learn how to send prompts to Gemini, handle streaming and synchronous responses, build a chatbot, process text and image inputs, extract structured data from raw text, use prompt templates, perform sentiment analysis, and implement Retrieval Augmented Generation (RAG). You’ll even learn how to use Gemma, Google’s open model on your local machine with Ollama. You'll leave with the skills to use Gemini in your Java or Python projects immediately with LangChain and LangChain4j.

Workshop 2: Cloud Runner 2049

Synth City is under threat. A powerful corporation's sinister plans have been uncovered by Synthia, a friendly AI with a rebellious spirit. In Cloud Runner 2049, you'll join Synthia to save the city. Immerse yourself in a neon-drenched world, master Google Cloud skills like Pub/Sub, Cloud Run, and Cloud Storage through five engaging quests, and thwart the corporation's catastrophic plot.
