LiteRT: The Universal Framework for On-Device AI
Blog post from Google Cloud
LiteRT, introduced in 2024, has evolved from its TensorFlow Lite foundation into a modern on-device AI framework, offering advanced hardware acceleration for developers. This evolution includes significant performance improvements, with GPU acceleration delivering 1.4x faster performance than TensorFlow Lite and new NPU capabilities providing up to 100x speed over CPU. LiteRT simplifies the deployment process with a unified workflow for GPU and NPU across platforms like Android, iOS, and Windows, supporting cross-platform Generative AI deployments for models such as Gemma. It enables seamless model conversion for PyTorch and JAX, ensuring compatibility with popular frameworks. LiteRT also offers a robust solution for reducing latency in real-time AI applications through asynchronous execution and zero-copy buffer interoperability. Additionally, the framework maintains long-term reliability and compatibility with the existing .tflite model format, catering to both existing and next-generation AI needs.
