Overview
Hush is an open-source noise suppression model developed by weya AI, designed to strip background noise and competing voices from real-time calls. It focuses on improving audio quality for voice AI agents, ensuring that ASR systems hear the main speaker clearly even in noisy environments like busy cafes, city streets, or construction sites. Hush is lightweight (8MB) and processes audio in under 1ms per 10ms frame on CPU, making it ideal for real-time applications.
Unsloth Desktop is an open-source application that allows users to run and train AI models locally on Mac and Windows devices. It supports a wide range of models, including LLMs, image/video diffusion, and audio models, with formats like GGUF and Safetensors. Unsloth offers no-code training workflows, auto dataset creation from documents, and a Model Arena for comparing models. It also provides optimized kernels for faster training and lower memory usage.
