%global base_description \
High-performance inference of OpenAI's Whisper automatic speech \
recognition (ASR) model: \
	\
* Plain C/C++ implementation without dependencies \
* Apple Silicon first-class citizen - optimized via ARM NEON, \
*  Accelerate framework, Metal and Core ML \
* AVX intrinsics support for x86 architectures \
* VSX intrinsics support for POWER architectures \
* Mixed F16 / F32 precision \
* 4-bit and 5-bit integer quantization support \
* Zero memory allocations at runtime \
* Support for CPU-only inference \
* Efficient GPU support for NVIDIA \
* Partial OpenCL GPU support via CLBlast \
* OpenVINO Support \
* C-style API
