The JavaScript AI Build-a-thon

4:00 หลังเที่ยง - 5:00 หลังเที่ยง (UTC)

Discover how to run powerful AI models entirely on-device using Foundry Local. We’ll cover the architecture, how to compile Hugging Face models for local execution, and how to integrate everything with LangChain.js. You’ll also see a compact Android demo showcasing low-latency, offline AI experiences. By the end, you’ll know how to set up, optimize, and build local-first AI apps, and how to join the private preview to go deeper. The Java-Script AI Build-a-thon

In this session, we explore the end-to-end journey of designing and developing AI solutions with Microsoft Foundry models. The session is structured around four key phases of the model development journey. We begin with Model Understanding, where you discover the Foundry model catalog and build intuition around core model capabilities. Next is Model Selection, focusing on how to choose the right model for a given use case using benchmarks, evaluations, and leaderboards. We then move into Model Customization, covering how models can be adapted through techniques such as context engineering, fine‑tuning, and compression to better meet application needs. Finally, we close with Model Observability, highlighting how evaluations, tracing, and monitoring help ensure models behave safely, reliably, and effectively at scale.

Get a practical introduction to building AI agents using the AI Toolkit Extension for VS Code. We’ll walk through agent design (core architecture), prompt engineering, function calling and MCP-powered tool use, tracing and evaluation using the extension. Expect a focused, actionable session that shows how to build agents that are reliable, observable, and ready for real-world scenarios. The Java-Script AI Build-a-thon

In this livestream, we officially kick off the Global Buildathon Hack, bringing builders from around the world together to apply what they’ve learned throughout the series and turn ideas into real, working AI solutions. We’ll walk through the hackathon theme, structure, timelines, and judging criteria, highlight the tools and resources available to participants, and share what success looks like - from learning outcomes to real‑world impact.
