About
Higgs Audio v3 Studio Runtime Files This repository hosts the downloadable runtime files for Higgs Audio v3 Studio, a Windows desktop app for local Higgs Audio v3 TTS, voice cloning, speech continuation, and multi-speaker generation. GitHub app repository: https://github.com/Saganaki22/Higgs-Audio-v3-Studio This repository is not the original upstream model release. It provides GGUF model builds, the Windows CUDA engine DLL package, checksums, and a manifest used by the desktop app downloader. What This Is Higgs Audio v3 Studio is a Rust/Tauri desktop application that runs a ported native C++/CUDA implementation of Higgs Audio v3 locally. The app provides: - Local TTS generation - Voice clone workflow - Continue speech workflow - Multi-speaker workflow - Speaker Gallery for reusable speaker identities - WAV/MP3 export - Local API server - API streaming endpoint - Whisper-assisted reference transcript workflow - Model/engine download UI - Hardware telemetry and VRAM diagnostics - Engine dependency diagnostics for missing CUDA/MSVC runtime DLLs App Download Use the desktop app from GitHub releases: https://github.com/Saganaki22/Higgs-Audio-v3-Studio/releases Source code: https://github.com/Saganaki22/Higgs-Audio-v3-Studio Runtime Repository Layout The app expects this Hugging Face repository layout: Available Downloads Recommended VRAM Engine Requirements The prebuilt engine package is intended for: - Windows x64 - NVIDIA RTX 30xx, 40xx, or 50xx GPU - CUDA 13 compatible NVIDIA driver - Higgs Audio v3 Studio 0.2.31 or newer recommended The engines/ folder contains the app engine DLL plus the CUDA/MSVC runtime DLLs the current Windows engine build needs. Important: - nvcuda.dll is not included and should not be uploaded here. - nvcuda.dll comes from the NVIDIA display driver. - Users still need a working NVIDIA driver installed. - Users should not need the full CUDA Toolkit installed if they use the app's Download Engine DLLs button. The app can use either: 1. DLLs already installed on the user's system, such as CUDA/MSVC runtime DLLs found through system paths. 2. DLLs downloaded from this repository into the app's writable engine folder. Engine Dependency Diagnost

Using it via the API
Once AxForge deploys higgs-audio-studio for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (higgs-audio-studio below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/audio/transcriptions \ -H "Authorization: Bearer $AXFORGE_API_KEY" \ -F model="higgs-audio-studio" -F file=@audio.mp3

Licence
The weights are open but its licence needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
