description: Union.ai is the commercial AI/ML orchestration platform built on the
  open-source Flyte project. It exposes the Flyte/Union control plane (the FlyteAdmin
  service) for registering and running strongly-typed workflows, tasks, and launch
  plans, plus Union Serverless, Actors, and Artifacts. The control plane is primarily
  a gRPC API (FlyteIDL AdminService) with an auto-generated HTTP/JSON gateway exposed
  under /api/v1/, driven by the union / pyflyte CLI and Flytekit / Union SDKs.
