Source description
A CoreML conversion of bond005/whisper-podlodka-turbo packaged for the WhisperKit runtime. Runs end-to-end on the Apple Neural Engine (ANE) on Apple Silicon Macs, iPhone, and iPad.
The upstream model is Ivan Bondarenko's Russian-focused fine-tune of , with improved noise robustness and reduced non-speech hallucinations. This repository contains only the converted weights - no architectural or training changes.

| File | Size | Purpose |
|---|---|---|
MelSpectrogram.mlmodelc | ~400 KB | Audio preprocessing (log-mel filterbank) |
AudioEncoder.mlmodelc | ~1.2 GB | 32-layer encoder, FP16 |
TextDecoder.mlmodelc | ~330 MB | 4-layer turbo decoder, FP16 |
config.json | - | Hugging Face Whisper config, inherited from the base model |
generation_config.json | - | Generation defaults, inherited from the base model |
All three .mlmodelc directories are pre-compiled MLProgram assets ready for direct use by WhisperKit. No additional compile step is required.
Inherited from the base model (Whisper Large v3 Turbo):
| Hyperparameter | Value |
|---|---|
| Encoder layers | 32 |
| Decoder layers | 4 |
| Hidden size (d_model) | 1280 |
| Attention heads (enc / dec) | 20 / 20 |
| Mel bins | 128 |
| Vocabulary | 51866 |
| Max source positions | 1500 (30 s @ 16 kHz) |
| Max target positions | 448 |

The tokenizer is the standard Whisper Large v3 tokenizer (vocab 51866) - WhisperKit will fetch it from openai/whisper-large-v3 if it is not present locally. Russian is the recommended decoding language for this model.
End-to-end ANE execution on an M-series Mac yields realtime factors significantly above 1.0x. First inference compiles ANE-specific kernels and may take noticeably longer; subsequent inferences use the cached compilation and are fast.
Primary: Russian. Secondary: English. The base fine-tune preserves the multilingual capability of Whisper Large v3 Turbo but is optimized for Russian ASR and Russian/English speech translation.
Apache 2.0, inherited from the base model.
