UiPath AI Center is a service that allows you to integrate and automate AI models into your RPA workflows. You can use pre-built or custom models, templates, and a drag-and-drop interface to deploy, manage, and improve your AI-enhanced automations. You can also consume the models within Studio or Orchestrator using the ML Skill activity or the ML Extract activity.
