Chalk is the data platform for inference, providing critical infrastructure that empowers teams to rapidly operationalize machine learning and AI. The developer-friendly platform consists of a Compute Engine that automatically compiles features into high-performance Rust pipelines without complex ETL, and an LLM Toolchain that seamlessly unifies structured and unstructured data.
"By moving our feature pipelines to Chalk, Data Science and Engineering now work side-by-side throughout model development. What used to be lengthy, error-prone handoffs are gone. Our entire search ranking stack runs on Chalk, serving features for inference in under 50ms, and we’re extending it to all of our models, including real‑time personalization."
