# QAic QDetect layers The QDetect layer is a proposed layer provided using Python to import and replace the existing detection layers (YoloLayer, SSDLayer, and so on) in the object detection models. This pluggable layer will eliminate the quantization-sensitive operations and will implement a custom operator that’s supported in the AIC backend. QDetect layers can be applied on a pregenerated ONNX model or can be included in the PyTorch source code itself and registered as a custom op. - [Model preparation](https://docs.qualcomm.com/doc/80-99100-3/topic/qaic_qdetect_layers_model_preparation.html) - [Compilation using `qaic-compile`](https://docs.qualcomm.com/doc/80-99100-3/topic/compilation_using_qaic_compile.html) Last Published: Aug 25, 2026 [Previous Topic Limitations](https://docs.qualcomm.com/bundle/publicresource/80-99100-3/topics/qaic-smart-nms-limitations.md) [Next Topic Model preparation](https://docs.qualcomm.com/bundle/publicresource/80-99100-3/topics/qaic_qdetect_layers_model_preparation.md)
