The whisper.cpp project says its quantized Whisper models require less memory and disk space, and that depending on the hardware they can be processed more efficiently.

Open the original- What it measures
- whisper.cpp is an open-source C/C++ port of OpenAI's Whisper model that runs on a personal computer or phone without a server. The project supports integer quantization of its ggml model files.
- What it does not show
- The README does not give a percentage for the memory or speed saving, and the trade-off in accuracy depends on the quantization level chosen.
