The different face detection models are optimized for different tasks. See the following table for an overview of the differences.

The best way to compare the performances of the detection models is to use them on a sample dataset. We recommend calling the [Detect] API on a variety of images, especially images of many faces or of faces that are difficult to see, using each detection model. Pay attention to the number of faces that each model returns.

### New detectable Face attributes
24+
25+
The glasses, occlusion, blur, and exposure attributes are available with the latest Detection 03 model. See [Specify a face detection model](./how-to/specify-detection-model.md) for more details.
