# Whisper large-v3 model for CTranslate2
This repository contains the conversion of Whisper `large-v3` to the [CTranslate2](https://github.com/OpenNMT/CTranslate2) model format.
This model can be used in CTranslate2 or projects based on CTranslate2 such as [faster-whisper](https://github.com/guillaumekln/faster-whisper).
## Example
```python
from faster_whisper import WhisperModel
model = WhisperModel("flyingleafe/faster-whisper-large-v3")
segments, info = model.transcribe("audio.mp3")
for segment in segments:
print("[%.2fs -> %.2fs] %s" % (segment.start, segment.end, segment.text))
```
## Conversion details
The original model was converted the following way:
```
# use Transformers convertation to HF format
python transformers/src/transformers/models/whisper/convert_openai_to_hf.py \
--checkpoint_path large-v3 --pytorch_dump_folder_path ./whisper-large-v3 --convert_tokenizer True
# ... some manual convertation to get `tokenizer.json` via `WhisperTokenizerFast` class ...
ct2-transformers-converter --model ./whisper-large-v3 --output_dir faster-whisper-large-v2 \
--copy_files tokenizer.json preprocessor_config.json --quantization float16
```
Note that the model weights are saved in FP16. This type can be changed when the model is loaded using the [`compute_type` option in CTranslate2](https://opennmt.net/CTranslate2/quantization.html).
