react-native-fast-tflite is a high-performance library that wraps the low-level TensorFlow Lite C/C++ API for React Native applications. It enables zero-copy ArrayBuffer access and GPU-accelerated inference through platform-specific delegates including CoreML, Metal, and OpenGL. The library allows developers to load .tflite model files at runtime and swap models without rebuilding the app, integrating with VisionCamera for real-time computer vision tasks.
