Building a Generative Recommender with Chronon - Feature Sstore Summit 2025

Leveraging modern techniques for recommendations — such as sequence and generative modeling — requires complex infrastructure to generate training data, process high-throughput event streams, and serve low-latency inference at scale. Chronon, an open-source feature platform built by Airbnb and Stripe and adopted by companies like OpenAI, Netflix, Roku, and Uber, simplifies these challenges. In this talk, we’ll show you how to use Chronon to streamline the data and feature engineering behind next-generation recommenders and deploy a robust, production-grade system. About the Speaker: Varant spent the last 10 years building data infrastructure for AI and ML at Airbnb and Palantir. During this time, he became one of the original authors of Chronon – the recently open sourced feature store. Currently, he is Co-Founder of Zipline AI, which is building an enterprise platform around the project.
