Feature Store

Every feature has a single source of truth

Chalk’s feature store powers production ML. Define features once, and Chalk computes them on demand for training, batch scoring, and inference. Features stay fresh and consistent across environments.

Explore Chalk Model Training

One feature definition everywhere

Define once, use across training, batch, and serving.

Execution first

Instead of just storing values, compute features at query time.

Point-in-time correctness

Recompute features as they would have been at inference time. No leakage, no skew.

Iterate fast with branches

Experiment quickly and safely on branches.

Low-latency serving

Serve precomputed or on-demand features in sub-5ms at scale.

Discoverability & governance

Built-in catalog, versioning, and metadata for auditability.
