AI on the QL601: Bringing Your Models to Life Fast with LiteRT on Python


Imagine you’ve trained an amazing AI model on your workstation. Now, it’s time for it to shine on the QL601 edge device. Whether you want HTP acceleration, GPU power, or just CPU execution, LiteRT on Python makes this transition seamless.

Deploying AI models to edge devices often means rewriting your entire pipeline, learning new frameworks, or accepting significant performance compromises. But what if you could keep your Python workflow intact while unlocking 10-20x performance gains?

LiteRT acts as the bridge between your existing Python workflow and Qualcomm’s optimized hardware. Instead of rewriting your pipeline, you convert your model to TFLite, attach the LiteRT delegate, and keep your preprocessing, postprocessing, and business logic intact. With only minor changes to the inference step, your Python app can continue running on your laptop or in the cloud while the QL601 handles fast, edge-ready inference.

LiteRT doesn’t rewrite your story—it simply makes your model run faster in the real world.

QL601: Precision Green Screen & Seamless CDN Streaming

As demand for video processing and live streaming continues to rise, developers need platforms that combine high performance with customizable media pipelines.

Through cross-compilation and GStreamer plugin development, green-screen removal on QL601 with Vulkan shaders enables real-time 1080p60/4Kp30 streaming to CDN platforms such as Twitch and YouTube — all built on the same development flow established for QL601.

The following sections detail the complete workflow, from environment setup and plugin development to real-time streaming deployment.

Voice Kiosk on QL601: Building a Low-Power, Voice-First Edge Terminal

Imagine walking up to a kiosk in a busy fast-food restaurant. Instead of tapping through a complex menu on a touchscreen, you simply say, "I'd like a cheeseburger, no onions, with a side of fries and a vanilla milkshake." The kiosk confirms your order instantly, and you're ready to pay. This isn't science fiction; it's the future of customer interaction, and it's powered by AI running directly at the edge.

How to Setup QL601 Development Environment

QL601 is a powerful single-board computer equipped with Qualcomm® QCS6490 chipset, along with AVerMedia software stack, helping developers to build AI-powered multimedia applications.

In this tutorial, we will guide you through the steps to set up the QL601 development environment, helping you to get started with the QL601 quickly.

How to Download Qualcomm AI Hub Models

Qualcomm AI Hub provides various AI models optimized for Qualcomm devices. This guide introduces two methods for downloading these models:
