whisper.cpp and whisper.net
One is a native C/C++ port of OpenAI's Whisper model, while the other is a .NET library designed to simplify speech-to-text using Whisper models, making them ecosystem siblings where the .NET library likely leverages or wraps the native C/C++ implementation or a similar backend.
About whisper.cpp
ggml-org/whisper.cpp
Port of OpenAI's Whisper model in C/C++
Optimized for resource-constrained environments through integer quantization, mixed-precision inference (F16/F32), and zero runtime memory allocations, enabling on-device ASR on mobile and embedded platforms. Leverages the GGML inference library with multi-platform GPU acceleration via Metal, Vulkan, CUDA, and Core ML, alongside CPU-optimized SIMD paths for ARM NEON, AVX, and POWER VSX architectures. Provides a minimal C API and supports deployment across iOS, Android, WebAssembly, Raspberry Pi, and standard desktop/server platforms.
About whisper.net
sandrohanea/whisper.net
Whisper.net. Speech to text made simple using Whisper Models
Provides .NET bindings to whisper.cpp with pluggable hardware acceleration across CPU, NVIDIA CUDA (13/12), Apple CoreML, Intel OpenVINO, and Vulkan runtimes. Automatically selects the optimal runtime based on platform and installed drivers, with priority fallback logic (e.g., CUDA 12 devices transparently downgrade from CUDA 13). Supports diverse platforms from Windows/Linux/macOS to mobile (iOS/Android) and WebAssembly, with custom native binary injection for advanced use cases.
