# Lite Runtime documentation Convert, optimize, and run Lite Runtime (LiteRT) models using delegates on Qualcomm^®^ Linux^®^ and Ubuntu. ## LiteRT overview High-level LiteRT overview Provides a high-level overview of the LiteRT framework, architecture, delegates, model conversion and quantization methods, and sample applications. https://docs.qualcomm.com/doc/80-70022-54/topic/tflite-landing-page.html#qualcomm-linux-debug-guide ## Get started with running LiteRT models Prerequisites to run LiteRT models Set up a Qualcomm development kit, upgrade it to the latest available software release, and flash the software image. https://docs.qualcomm.com/doc/80-70022-54/topic/getting-started.html#getting-started Run a LiteRT model using the GStreamer-based Qualcomm^®^ Intelligent Multimedia SDK Download the required files and use the gst-ai-classification precompiled sample application to run a LiteRT classification model on Qualcomm development kits. https://docs.qualcomm.com/doc/80-70022-54/topic/getting-started.html#run-a-tensorflow-lite-model-using-the-gstreamer-based-qim-sdk Run a LiteRT model using the native LiteRT sample application Download the required files and use the label\_image native sample application to run a LiteRT classification model on Qualcomm development kits. https://docs.qualcomm.com/doc/80-70022-54/topic/getting-started.html#run-a-tensorflow-lite-model-using-a-native-tensorflow-lite-sample-application ## LiteRT architecture LiteRT on-device inference overview Learn how LiteRT on-device inference loads a model, which is subsequently parsed and executed by the interpreter using a delegate. https://docs.qualcomm.com/doc/80-70022-54/topic/arch.html#tensorflow-lite-runtime Accelerate LiteRT models using delegates Use delegates to speed up models efficiently on the CPU, GPU, and specialized Qualcomm hardware, such as the Qualcomm^®^ Adreno^™^ GPU and the Qualcomm^®^ Hexagon^™^ Tensor Processor. https://docs.qualcomm.com/doc/80-70022-54/topic/arch.html#delegates Qualcomm^®^ AI Engine direct delegate interface Include the `QnnTFLiteDelegate.h` header and link the appropriate Qualcomm^®^ Neural Network (QNN) delegate library for application compatibility. https://docs.qualcomm.com/doc/80-70022-54/topic/arch.html#section-qsn-xjp-tbc ## Deploy a LiteRT model Use a pre-optimized LiteRT model Download and use ready-to-deploy LiteRT models from the open-source community or Qualcomm^®^ AI Hub. https://docs.qualcomm.com/doc/80-70022-54/topic/tensorflow-lite-developer-workflow.html#use-an-existing-tensorflow-lite-model Convert a TensorFlow model to a LiteRT model Use Python APIs and the `tflite_convert` command to convert models to the LiteRT format. https://docs.qualcomm.com/doc/80-70022-54/topic/tensorflow-lite-developer-workflow.html#convert-tensorflow-lite-models Create an application and run inference Create an application using LiteRT C++ APIs to load a LiteRT model and run inference. https://docs.qualcomm.com/doc/80-70022-54/topic/tensorflow-lite-developer-workflow.html#run-inference Develop a custom application Use the qtimltflite GStreamer-based plug-in to develop your own application and run LiteRT models. https://docs.qualcomm.com/doc/80-70022-54/topic/tensorflow-lite-developer-workflow.html#develop-a-custom-application-to-run-the-tensorflow-lite-model ## Run LiteRT sample applications Prerequisites to run LiteRT sample applications Download and copy models, label files, and a sample image to the device to run the label\_image sample application. https://docs.qualcomm.com/doc/80-70022-54/topic/sample-applications.html#download-models-and-sample-images Run a LiteRT model using an available delegate Run LiteRT models using delegates, such as XNNPACK and GPU, to benchmark model execution. https://docs.qualcomm.com/doc/80-70022-54/topic/sample-applications.html#label-image-tool Run the QNN delegate using an external delegate Use the Qualcomm AI Engine direct API as an external delegate, along with the associated libraries, to run the QNN delegate. https://docs.qualcomm.com/doc/80-70022-54/topic/sample-applications.html#run-qnn-delegate-using-the-external-delegate-interface ## Build LiteRT Optional: Build LiteRT Recompile LiteRT in specific scenarios such as when you want to change the LiteRT library version. https://docs.qualcomm.com/doc/80-70022-54/topic/build-qualcomm-linux-and-install-tensorflow-lite-runtime.html#build-qualcomm-linux-and-install-tensorflow-lite-runtime Last Published: Dec 03, 2025 [Next Topic LiteRT overview](https://docs.qualcomm.com/bundle/publicresource/80-70022-54/topics/tflite-landing-page.md)
