## Whisper model files in custom ggml format
The [original Whisper PyTorch models provided by OpenAI](https://github.com/openai/whisper/blob/main/whisper/__init__.py#L17-L27)
have been converted to custom `ggml` format in order to be able to load them in C/C++. The conversion has been performed using the
[convert-pt-to-ggml.py](convert-pt-to-ggml.py) script. You can either obtain the original models and generate the `ggml` files
yourself using the conversion script, or you can use the [download-ggml-model.sh](download-ggml-model.sh) script to download the
already converted models from https://ggml.ggerganov.com
