The tensor operators are optimized heavily for Apple silicon CPUs. Depending on the computation size, Arm Neon SIMD
intrinsics or CBLAS Accelerate framework routines are used. The latter are especially effective for bigger sizes since
the Accelerate framework utilizes the special-purpose AMX coprocessor available in modern Apple products.

## Whisper model files in custom ggml format
## 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)
The [original Whisper PyTorch models provided by OpenAI](https://github.com/openai/whisper/blob/main/whisper/__init__.py#L17-L30)
are converted to custom `ggml` format in order to be able to load them in C/C++.
Conversion is 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.
Currently, they are hosted on the following locations:
There are three ways to obtain `ggml` models:
- https://huggingface.co/ggerganov/whisper.cpp
- https://ggml.ggerganov.com
### 1. Use [download-ggml-model.sh](download-ggml-model.sh) to download pre-converted models
Sample download:
Example download:
```java
```text
$ ./download-ggml-model.sh base.en

$ ./main -m models/ggml-base.en.bin -f samples/jfk.wav
```
To convert the files yourself, use the convert-pt-to-ggml.py script. Here is an example usage.
The original PyTorch files are assumed to have been downloaded into ~/.cache/whisper
Change `~/path/to/repo/whisper/` to the location for your copy of the Whisper source:
```
### 2. Manually download pre-converted models
`ggml` models are available from the following locations:
- https://huggingface.co/ggerganov/whisper.cpp/tree/main
- https://ggml.ggerganov.com
### 3. Convert with [convert-pt-to-ggml.py](convert-pt-to-ggml.py)
Download one of the [models provided by OpenAI](https://github.com/openai/whisper/blob/main/whisper/__init__.py#L17-L30) and generate the `ggml` files using the [convert-pt-to-ggml.py](convert-pt-to-ggml.py) script.
Example conversion, assuming the original PyTorch files have been downloaded into `~/.cache/whisper`. Change `~/path/to/repo/whisper/` to the location for your copy of the Whisper source:
```bash
mkdir models/whisper-medium
python models/convert-pt-to-ggml.py ~/.cache/whisper/medium.pt ~/path/to/repo/whisper/ ./models/whisper-medium
mv ./models/whisper-medium/ggml-model.bin models/ggml-medium.bin
rmdir models/whisper-medium
```
A third option to obtain the model files is to download them from Hugging Face:

Models are multilingual unless the model name includes `.en`. Models ending in `-q5_0` are [quantized](../README.md#quantization). Models ending in `-tdrz` support local diarization (marking of speaker turns) using [tinydiarize](https://github.com/akashmjn/tinydiarize). More information about models is available [upstream (openai/whisper)](https://github.com/openai/whisper#available-models-and-languages). The list above is a subset of the models supported by the [download-ggml-model.sh](download-ggml-model.sh) script, but many more are available at https://huggingface.co/ggerganov/whisper.cpp/tree/main and elsewhere.
