Introduction of ZONOS2-BF16
Model Details of ZONOS2-BF16
ZONOS2-BF16
This repository provides a BF16 Safetensors conversion of the original Zyphra/ZONOS2 model for use with the ZONOS2 TTS ComfyUI custom node .
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:
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 Storage Location
Place the model and required assets under:
ComfyUI/
└── models/
└── zonos2/
├── zonos2-bf16.safetensors
├── dac_44khz/
└── speaker_encoder/
Expected layout:
ComfyUI/models/zonos2/

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.
License
The original ZONOS2 model is released under the Apache License 2.0.
This converted Safetensors package follows the same model license.
