In this talk, building upon the success of our corporate self-service API platform, we will cover the journey that led to our platform approach for scaling AI development in a large enterprise such as OMV, emphasizing maintainability and component reuse. In addition to delving into the architectural and specific implementation details of our OMV AI Hub, we will demonstrate the productive web portal, which provides end users with safe GenAI products and AI engineers with reusable, governed modules and comprehensive documentation. We will discuss the benefits of stable reference architectures and the significance of a self-service platform, as well as the real-world challenges that come along the way.
