Chalk is a real-time platform for machine learning that simplifies data infrastructure for data teams. It enables developers to focus on building unique products and models by providing a seamless experience for declaring features and their dependencies in Python. Chalk compiles these definitions into parallel pipelines running on a Rust-based engine, ensuring consistency between training sets and live feature values. With capabilities like high-volume workloads, ultra-low latency, and observability, Chalk has become a critical component for companies like Ramp, enhancing their risk intelligence and fraud detection processes.
