From image analysis to small language models, MLange is the fastest and simplest way for developers to integrate AI into apps, whether using open-source or custom models. The platform automatically converts any AI model into a ready-to-deploy on-device format, performs performance benchmarking across 200+ smartphone models (iOS and Android), and provides developers with just three lines of code to integrate AI into their projects. We support PyTorch, ONNX, TFLite, LiteRT, ExecuTorch model formats, and automatically distribute the most performing runtime for each target end device.
