Teams use it for the context their models and agents need (Database Engine, Feature Store, 5ms Serving), the runtime to serve and run them (Model Serving, GPUs, Sandboxes, Model Gateway), and the loop that makes them better (Evals, Traces, Notebooks, Fine-Tuning). Trusted by enterprises including Whatnot, Grindr, Mission Lane, Turo, and Apartment List, Chalk brings together context, runtime, and learning for agents and models.
