Source description
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 for easier loading, safer serialization, and direct integration with ComfyUI workflows.

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.
zonos2
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.

If download_if_missing is enabled in the ComfyUI node, missing assets can be downloaded automatically.
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.
