Abstract: Methods, systems, and apparatus, including computer-readable media, for data preparation and modeling using artificial intelligence. In some implementations, a system receives user input that indicates one or more data sets. In response, the system generates a set of recommendations for data modeling, data preparation, or data enrichment for the one or more data sets, where at least one recommendation in the set of recommendations is generated using one or more artificial intelligence and/or machine learning (AI/ML) models. The system provides the set of recommendations for display in the user interface in association with one or more interactive controls to accept or dismiss the recommendations. In response to receiving user input the system updates the data model or the one or more data sets to apply an update corresponding to an accepted recommendation. The system provides the updated data set or updated data model to a chatbot or other application.
