Ming-3.0-audio-tiny

Hear clearly. Understand deeply. Act intelligently.

Ming-3.0-audio-tiny is a compact native audio-language model from inclusionAI. It accepts audio together with text instructions and supports speech recognition, spoken question answering, audio understanding, audio reasoning, and optional synthesized-speech responses.

Model Summary

Property	Description
Developer	inclusionAI
Model type	Compact native audio-language Mixture-of-Experts model
Parameters	9.3B total parameters, 2.7B activated per inference step
Inputs	Audio and text instructions
Outputs	Text, or text with optional synthesized speech
Primary languages	Chinese and English, including varied accents and dialects
License	MIT

Highlights

Efficient audio intelligence: Provides speech and audio understanding in a compact Mixture-of-Experts model.
Complex speech recognition: Handles Chinese and English speech, dialects, accents, noisy environments, and multi-speaker recordings.
Long-audio understanding: Comprehends and analyzes long-form recordings.
Multidimensional perception: Understands speech, non-speech sounds, acoustic scenes, and music.
Audio reasoning: Answers questions and performs reasoning over audio content.
Audio interaction: Produces text responses and can optionally synthesize speech with built-in voices or a reference voice.

Architecture

Ming-3.0-audio-tiny combines an audio encoder and projector with a compact Mixture-of-Experts language backbone. An optional Talker generates speech responses from the model's output.

Quick Start with Transformers

The model uses custom Transformers code. Review the repository code before enabling trust_remote_code=True.

bash

git clone https://github.com/inclusionAI/Ming-3.0-audio-flash.gitcd Ming-3.0-audio-flash
python -m venv .venv-transformerssource .venv-transformers/bin/activatepip install -r requirements-transformers.txt

Audio Understanding

Speech Recognition

The validated ASR prompt asks the model to identify the spoken language and place a tab between the language label and transcription.

Direct Python Usage

python

import torchfrom transformers import AutoModelForCausalLM, AutoProcessor
model_id = "inclusionAI/Ming-3.0-audio-tiny"audio_path = "examples/audio/introduce_ant_group.wav"
processor = AutoProcessor.from_pretrained(    model_id,    trust_remote_code=True,    use_fast=False,)model = AutoModelForCausalLM.from_pretrained(    model_id,    dtype=torch.bfloat16,    device_map="auto",    trust_remote_code=True,).eval()
messages = [    {        "role": "user",        "content": [            {"type": "audio", "audio": audio_path},            {"type": "text", "text": "Please answer the question in the audio."},        ],    }]
inputs = processor(messages).to(model.device)inputs["audio_feats"] = inputs["audio_feats"].to(model.dtype)
with torch.inference_mode():    output_ids = model.generate(        **inputs,        max_new_tokens=512,        do_sample=False,    )
generated_ids = output_ids[0, inputs["input_ids"].shape[1] :]response = processor.decode(generated_ids, skip_special_tokens=True).strip()print(response)

Speech Output

The Talker example supports built-in voices and reference-audio voice prompting:

See the voice guide for available voice names, invocation rules, and reference-audio usage.

Serving

vLLM-Omni

Text output or ASR uses the Tiny Thinker on one GPU:

For synthesized-speech output, select the full-audio profile:

The reference full-audio profile places the Thinker on GPU 0 and the Talker on GPU 1. Select the deployment YAML that matches text-only, ASR, or Talker output. See the deployment guide for details.

Select an IP or registered voice with the vLLM-Omni client's --voice option:

The client sends this selection as Chat Completions audio.voice: {"id": "..."}. vLLM-Omni uses the built-in IP voice 灵小柔 when no voice is specified. The model directory also provides 灵楷 and US_James as preset reference voices under voice_presets/voice_audio/, with their matching transcripts in voice_presets/voice_prompts.json. Both names are also available as built-in IP voices.

SGLang

The validated Tiny SGLang profile uses one GPU and provides text output. See the SGLang example for client usage.

SGLang-Omni

SGLang-Omni serves transcription, audio chat, and speech synthesis from one server. The Tiny checkpoint fits on a single GPU; --talker.gpu 0 colocates speech synthesis with the other stages:

The server exposes OpenAI-compatible /v1/audio/transcriptions, /v1/audio/speech, and /v1/chat/completions endpoints. The SGLang-Omni cookbook shows client examples; the same requests work with the Tiny model name.
