-The custom neural (custom document) model uses deep learning models and  base model trained on a large collection of documents. This model is then fine-tuned or adapted to your data when you train the model with a labeled dataset. Custom neural models support extracting key data fields from structured, semi-structured, and unstructured documents. When you're choosing between the two model types, start with a neural model to determine if it meets your functional needs. See [neural models](custom-neural.md) to learn more about custom document models.

 ### Custom classification model
 
  Document classification is a new scenario supported by Document Intelligence with the ```2023-07-31``` (v3.1 GA) API. The document classifier API supports classification and splitting scenarios. Train a classification model to identify the different types of documents your application supports. The input file for the classification model can contain multiple documents and classifies each document within an associated page range. To learn more, *see* [custom classification](custom-classifier.md) models.
