Towards LLM-powered consistency in model-based low-code platforms

Low-code platforms often use various models that define the application built by citizen developers.
With the increasing size and complexity of the applications built using low-code platforms, the number of required models and the dependencies between them expand.
However, with increased complexity, keeping these models consistent during the development or evolution of the application is crucial and often a non-trivial task for citizen developers.
In this paper, we present four approaches to how LLMs can be used and integrated on the architecture level into low-code platforms to (i) create consistent models automatically, (ii) keep models consistent based on different types of dependencies, and (iii) support users in maintaining consistent models during the development.
We implemented the approaches in a prototype and evaluated them in an exploratory study.
The results show that state-of-the-art LLMs are capable of preserving consistency for low-code models as well as generating correct and consistent models in various scenarios.
