Vui TTS (100M base)

This repository hosts the Vui 100M base checkpoint and Fluac tokenizer used by the fluxions/vui project.

Contents:

• vui-100m-base.pt: Vui TTS checkpoint (100M parameters).
• fluac-22hz-22khz.pt: Fluac codec checkpoint.
• LICENSE: MIT license from the upstream project.

Quick usage (Python)

import torch
from huggingface_hub import hf_hub_download
from vui.inference import render
from vui.model import Vui

# Download checkpoints from this repo (returns local file paths)
ckpt = hf_hub_download("Endy2001/vui-tts", "vui-100m-base.pt")
codec_ckpt = hf_hub_download("Endy2001/vui-tts", "fluac-22hz-22khz.pt")

# Load model (pass codec checkpoint so it doesn't fetch from upstream)
model = Vui.from_pretrained_inf(ckpt, codec_checkpoint=codec_ckpt).to("cuda")

text = "Hello! This is Vui speaking from Hugging Face."
with torch.inference_mode():
    audio = render(model, text)[0].cpu().numpy()
# `audio` is a mono waveform at 24 kHz

Notes

• This is a TTS model with a custom architecture; it is not a standard CausalLM.
• vllm serve only supports text-generation transformer architectures, so this checkpoint cannot be served directly via vllm serve Endy2001/vui-tts. Use the Python API above or the scripts in the upstream repo instead.
