| # ZONOS2-BF16 |
|
|
| This repository provides a **BF16 Safetensors conversion** of the original [Zyphra/ZONOS2](https://huggingface.co/Zyphra/ZONOS2) model for use with the [ZONOS2 TTS ComfyUI custom node](https://github.com/Saganaki22/Zonos2_TTS-ComfyUI). |
|
|
| The model was converted from the original PyTorch checkpoint format to `.safetensors` for easier loading, safer serialization, and direct integration with ComfyUI workflows. |
|
|
|  |
|
|
| ## Original Project |
|
|
| ZONOS2 is a text-to-speech model from Zyphra trained on more than 6 million hours of varied multilingual speech. It supports expressive speech generation and high-fidelity voice cloning. |
|
|
|
|
|  |
|
|
|
|
| ## ComfyUI Custom Node |
|
|
| This model package is intended for use with: |
|
|
| - https://github.com/Saganaki22/Zonos2_TTS-ComfyUI |
| |
| The ComfyUI node provides native ZONOS2 text-to-speech, audio-only voice cloning, BF16/FP16 loading, SDPA/FlashAttention inference, progress reporting, and ComfyUI/AIMDO model-management integration. |
| |
| ## Model File |
| |
| Main model file: |
| |
| - `zonos2-bf16.safetensors` |
| |
| Direct download: |
| |
| - https://huggingface.co/drbaph/ZONOS2-BF16/resolve/main/zonos2-bf16.safetensors?download=true |
| |
| ## Model Storage Location |
| |
| Place the model and required assets under: |
| |
| ComfyUI/ |
| └── models/ |
| └── zonos2/ |
| ├── zonos2-bf16.safetensors |
| ├── dac_44khz/ |
| └── speaker_encoder/ |
| |
| Expected layout: |
|
|
| ComfyUI/models/zonos2/ |
| ├── zonos2-bf16.safetensors |
| ├── dac_44khz/ |
| │ ├── config.json |
| │ ├── dac_model.bin |
| │ └── preprocessor_config.json |
| └── speaker_encoder/ |
| ├── config.json |
| ├── model.safetensors |
| └── preprocessor_config.json |
| |
| If `download_if_missing` is enabled in the ComfyUI node, missing assets can be downloaded automatically. |
|
|
| ## Usage |
|
|
| Install the ComfyUI custom node: |
|
|
| cd ComfyUI/custom_nodes |
| git clone https://github.com/Saganaki22/Zonos2_TTS-ComfyUI.git |
| |
| Then restart ComfyUI and load the ZONOS2 model from the node loader. |
|
|
| ## Notes |
|
|
| - This repository is a converted BF16 Safetensors package of the original ZONOS2 model. |
| - The model architecture and original weights come from Zyphra/ZONOS2. |
| - This package is provided for ComfyUI compatibility and convenience. |
| - Voice cloning should only be used with voices you own or have explicit permission to use. |
