HUD (Human Union Data, Inc.) is a platform for building reinforcement-learning environments, tasks and benchmarks used to train and evaluate AI agents and models. Teams create environments with the open-source hud Python SDK and CLI or import Harbor tasks, run evaluations across frontier models, inspect traces, run automated QA agents that detect grader mistakes and reward hacking, train models on their own environments, and can list task data on DataVendor. The platform is exposed through a REST API at api.beta.hud.ai (routes under /v2, team API-key authentication).
