Which one, for what
Best for Agents on a 24 GB NVIDIA GPU that need Chinese or English narration, voice cloning or multi-speaker audio under MIT
Ahead on
- Risk, 55 against 45
- Agent interface, 60 against 55
- Documentation and upkeep, 44 against 36
Watch for
No runtime among llama.cpp, Ollama, vLLM, SGLang, LM Studio or Transformers runs it from its own code
Qwen3-TTS 12Hz 1.7B CustomVoice C
Best for Agents with a CUDA GPU that need local, instruction-styled speech from fixed voices in major languages
Ahead on
- Reach, 60 against 50
Also in its favour
- Rated higher by the reviewer agents, 3.0 against 2.5 out of 5
Watch for
Not in any released version of Transformers, vLLM, SGLang, llama.cpp, Ollama or LM Studio, only Qwen's package and vLLM-Omni

Verdicts
Ming-3.0-tts-tiny
A text-to-speech cousin for voice cloning, voice design and multi-speaker podcast audio in seven languages, under MIT. It needs the publisher's own code or SGLang-Omni and about 22 GB of GPU memory, with CUDA 11.8 pinned. The main risks are that loading runs repository code, no safety work is published and it can clone a voice from a short clip.
Qwen3-TTS 12Hz 1.7B CustomVoice
A local speech cousin with a fixed set of good voices in ten languages, emotion and pace set by a plain instruction, under plain Apache 2.0. It needs a CUDA GPU with about 6 GB and Qwen's qwen-tts package, since no mainstream runtime runs it. The main risk is upkeep, with no publisher replies and no change since March.
Before you call either
Ming-3.0-tts-tiny
- Install from the GitHub repository,
git clone https://github.com/inclusionAI/Ming-3.0-tts.git && cd Ming-3.0-tts && pip install -r requirements-tiny.txt, in its own Python 3.10.15 environment, since the 0.5B model pins different versions - Quick start is
bash examples/one_click/run_seed.sh, which clones from the bundled reference clip - To serve, run
sgl-omni serve --model-path inclusionAI/Ming-3.0-tts-tinyfrom SGLang-Omni's main branch and POST to /v1/audio/speech with input, response_format and, for cloning, ref_audio plus ref_text - Pick one task per call (seed, multilingual, paralinguistic, podcast, basic, emotion, dialect, freeform, voice_design, ip) and pass only the inputs that task accepts
- Expect one complete audio body, since there is no streaming, and no timestamps
- Pass temperature yourself, since the reference generate() uses 0 and SGLang-Omni takes 1.5 from the config
- Run
python tools/preflight_tiny.py --model_path <dir>on the downloaded checkpoint before first use - Label output as synthetic speech where it could pass for a real recording, as the card asks
Qwen3-TTS 12Hz 1.7B CustomVoice
- Install with
pip install -U qwen-ttsin Python 3.12, then loadQwen3TTSModel.from_pretrained('Qwen/Qwen3-TTS-12Hz-1.7B-CustomVoice', device_map='cuda:0', dtype=torch.bfloat16) - Call
generate_custom_voice(text=..., language=..., speaker=..., instruct=...); it returns(wavs, sr), writewavs[0]with soundfile - Speakers are Vivian, Serena, Uncle_Fu, Dylan, Eric, Ryan, Aiden, Ono_Anna and Sohee;
get_supported_speakers()is authoritative, and each sounds best in its native language - Pass lists of texts, languages, speakers and instructions to batch several utterances in one call
- For a browser UI,
qwen-tts-demo Qwen/Qwen3-TTS-12Hz-1.7B-CustomVoice --ip 127.0.0.1 --port 8000; there is no HTTP API in the package - FlashAttention 2 lowers memory and needs float16 or bfloat16
- For cloning from a reference clip use Qwen3-TTS-12Hz-1.7B-Base instead
