| # IndicF5 MNN |
|
|
| MNN exports of [ai4bharat/IndicF5](https://huggingface.co/ai4bharat/IndicF5) (DiT + Vocos), including fp16 and int8 weight-quantized variants. |

| ### DiT |
|
|
| | File | Approx. size | |
| |------|----------------| |
| | `indicf5_dit_fp32.mnn` | ~1.3 GB | |
| | `indicf5_dit_fp16.mnn` | ~646 MB | |
| | `indicf5_dit_int8wq.mnn` | ~347 MB | |
| | `indicf5_dit_fp16_int8wq.mnn` | ~646 MB | |
|
|
| ### Vocos |
|
|
| | File | Notes | |
| |------|--------| |
| | `indicf5_vocos_fp32.mnn` | static | |
| | `indicf5_vocos_fp32_dynamic.mnn` | variable mel frames (recommended for audio) | |
| | `indicf5_vocos_fp16.mnn` | | |
| | `indicf5_vocos_int8wq.mnn` | static | |
| | `indicf5_vocos_int8wq_dynamic.mnn` | variable mel frames | |
| | `indicf5_vocos_fp16_int8wq.mnn` | | |
|
|
| Sample WAVs (fp32 / int8wq Vocos decode) are under `samples/`. Bench numbers: `quant_benchmark.json`. |
|
|
| ## Notes |
|
|
| - Prefer `*_dynamic.mnn` Vocos models for full-length audio (call `resizeTensor` with a **tuple** shape, then `resizeSession`). |
| - Path used for samples: PyTorch mel → MNN Vocos. |
| - Still not realtime on Apple M1 CPU for full DiT ODE + Vocos. |
