Overview
Chalk is a data platform powering machine learning and generative AI. Its developer experience lets data teams declare features and dependencies in idiomatic Python across online, streaming and batch environments. It compiles these definitions into parallel pipelines running on a Rust-based engine. Using exactly the same source code, these pipelines give data scientists time-consistent training sets and provide models with real-time feature values. This reuse ensures matching feature values online and offline and greatly reduces development time. With Chalk, engineers, data scientists and analysts can focus on products while managing data infrastructure.
