Own Your AI: Build an Agentic AI Model Factory - Hack Night SF

Build a Sovereign AI Model Factory: an ML Engineer Agent that evaluates, fine-tunes, deploys, and improves open models using Union on your cloud. The best AI teams aren't renting every capability from an external API, they're building systems they own and control. In this hands-on session at the AWS Loft, we'll build exactly that. We'll start with a walkthrough where we build a LangGraph-powered agent that evaluates open models in parallel, fine-tunes promising candidates, deploys the winner, and retrains automatically when performance drops. Think of it as the first brick in your own model factory: a repeatable system for evaluating, improving, and deploying models you control, not a black box you call and hope for the best. Along the way, you'll see how Union.ai gives your workflows a durable runtime with infrastructure as context, so agents adapt infra resources, recover from failures, and keep moving without re-running completed work. And because it all runs in your own AWS account, you own the full stack end to end: your models, your data, your infrastructure, your IP. Then we switch into hack night mode: keep building on the example, bring your own models or datasets, experiment with evals and fine-tuning, extend open models to different parts of your agent, or start something new around the same ideas. For teams thinking about sovereign AI, this is a practical starting point for owning more of your stack, the weights, the training loop, the evals, and the infrastructure it runs on, all on AWS. Bring a laptop. Leave with a factory. All guests must be 18+ and present a valid government-issued physical photo ID at check-in (digital IDs are not accepted). Scooters and bikes are not permitted in any Amazon building, and there is no on-site parking.
