It's been a few months now that AI Builder has been released in preview within the Power Platform and this month, some of the features it contains are released in GA.
Besides the Business Card Reader component, all of the presented options require training with historical data, images or documents. This allows the models, such as Prediction, Text Classification, Object Detection and Form Processing to be adapted to your organization's specificities. But it also means that you have to gather that data, understand it, classify it and process it within the AI Builder tools.
Custom AI Builder models
What prebuilt models bring to the table are options to answer use cases where you can leverage common knowledge and expertise that Microsoft has already cumulated. The early example that was already available is the Business Card Reader component in the Canvas App maker.

With this component, you have the ability to take a picture of a business card in your Canvas App and get the extracted name, email, phone number and other valuable data to push it over within your CDS leads for example.
