## Integration with Zen Dub
Zen Omni integrates with zen-dub for video dubbing:
```python
from zen_omni import ZenDubbingPipeline
pipeline = ZenDubbingPipeline()
pipeline.dub("video.mp4", target_lang="en", output_path="dubbed.mp4")
```
Pipeline stages:
1. Extract audio from video
2. Translate speech with Zen Omni
3. Generate lip-synced video with Zen Dub
4. Composite final output
## Key Technologies
- **Qwen3-Omni**: Base multimodal architecture
- **ms-swift**: ModelScope fine-tuning framework
- **MuseTalk**: Neural lip synchronization (zen-dub)
- **Whisper**: Audio feature extraction
- **DeepSpeed**: Distributed training
## Development Workflow
1. Download base model: `hf download Qwen/Qwen3-Omni-30B-A3B-Instruct --local-dir ./base-model`
2. Identity fine-tuning: `./training/train_identity.sh`
3. Test locally: `zen-omni chat`
4. Upload to HuggingFace: `./scripts/upload_hf_cards.sh`
## Context for All AI Assistants

1. **ALWAYS** update LLM.md with significant discoveries
2. **NEVER** commit symlinked files (.AGENTS.md, CLAUDE.md, etc.) - they're in .gitignore
3. **NEVER** create random summary files - update THIS file
4. Zen models are based on **Qwen3** (NOT Qwen2!)
5. Use `hf` CLI for HuggingFace operations
6. Test-driven development - always verify before marking complete

you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the

| **Architecture** | `Qwen3OmniMoeForConditionalGeneration` |
| **Total Parameters** | 30B |
| **Active Parameters** | 3B (via MoE sparse activation) |
| **Specialization** | Extended reasoning with thinking tokens |
| **Thinking Budget** | Up to 32K tokens |
| **Context Length** | 32,768 tokens |
| **License** | Apache 2.0 |
## Use Cases
- **Complex Problem Solving**: Multi-step reasoning tasks
- **Mathematical Reasoning**: Step-by-step mathematical proofs
- **Code Analysis**: Understanding and debugging complex code
- **Scientific Reasoning**: Analyzing experimental data
- **Strategic Planning**: Long-horizon planning with explicit reasoning
## Quick Start
```python
from transformers import Qwen3OmniModel, Qwen3OmniProcessor
model = Qwen3OmniModel.from_pretrained(
"zenlm/zen-omni-30b-thinking",
torch_dtype="auto",
device_map="auto"
)
processor = Qwen3OmniProcessor.from_pretrained("zenlm/zen-omni-30b-thinking")
# Enable thinking mode
messages = [
{"role": "system", "content": "You are Zen, a reasoning AI. Think step by step."},
{"role": "user", "content": "Solve: If a train travels at 60 mph for 2 hours, then 80 mph for 3 hours, what is the average speed?"}
]
inputs = processor.apply_chat_template(messages, return_tensors="pt")
outputs = model.generate(
**inputs.to(model.device),
max_new_tokens=4096,
enable_thinking=True, # Enable thinking tokens
)
response = processor.decode(outputs[0], skip_special_tokens=False)
```
## Thinking Mode Output
The model generates explicit reasoning in `<think>` tags:
```
<think>
Let me break this down step by step:
1. Distance in first segment: 60 mph × 2 hours = 120 miles
2. Distance in second segment: 80 mph × 3 hours = 240 miles
3. Total distance: 120 + 240 = 360 miles
4. Total time: 2 + 3 = 5 hours
5. Average speed = Total distance / Total time
</think>
The average speed is 360 miles ÷ 5 hours = 72 mph.
```
## Visual Reasoning
```python
from PIL import Image
image = Image.open("complex_diagram.png")
messages = [{"role": "user", "content": [
{"type": "image", "image": image},
{"type": "text", "text": "Analyze this diagram and explain the relationships shown. Think through your reasoning."}
]}]
inputs = processor(messages, return_tensors="pt")
outputs = model.generate(
**inputs.to(model.device),
max_new_tokens=4096,
enable_thinking=True
)
```

# Zen Omni: Hypermodal Language Model for Translation and Audio Generation
**Technical Report v1.0**
**Authors**: Zen LM Team, Hanzo AI
**Abstract**: We introduce Zen Omni, a family of hypermodal language models built on Qwen3-Omni-30B-A3B, designed for real-time speech translation, video dubbing, and multimodal understanding. Zen Omni combines the Thinker-Talker architecture with efficient sparse activation (30B total, 3B active parameters) to enable high-quality speech-to-speech translation across 119 text languages, 19 speech input languages, and 10 speech output languages. Integrated with Zen Dub for neural lip synchronization, the complete pipeline enables production-ready video dubbing with voice preservation and natural lip movements.
## 1. Introduction
The demand for real-time, high-quality translation with preserved speaker characteristics has grown significantly with globalized content creation. Traditional approaches rely on cascaded systems: ASR → MT → TTS → Lip Sync, each introducing latency and error propagation.
Zen Omni takes an end-to-end approach, leveraging the native multimodal capabilities of Qwen3-Omni to:
1. Directly understand speech without intermediate ASR
2. Generate translated speech with preserved prosody
3. Integrate seamlessly with neural lip synchronization
## 2. Architecture
### 2.1 Base Model: Qwen3-Omni-30B-A3B
Zen Omni is built on Qwen3-Omni's Thinker-Talker architecture:
```

│ │ └── 2048 codebook size │
│ ├── Streaming synthesis │
│ └── 24kHz output sample rate │
│ │
└─────────────────────────────────────────────────────────────┘
```
### 2.2 Sparse Activation
The MoE architecture enables efficient inference:
- **Total Parameters**: 30B
- **Active Parameters**: 3B per token
- **Expert Selection**: Top-8 gating per token
- **Memory Efficiency**: Reduced activation memory vs dense models
### 2.3 Multimodal Fusion
The Thinker component uses cross-modal attention to align representations:
- Audio features projected to transformer dimension
- Vision features via learnable queries
- Text embeddings shared with output vocabulary
## 3. Zen Dub Integration
### 3.1 Neural Lip Synchronization
Zen Dub uses MuseTalk v1.5 architecture for lip sync:
```
Audio Input → Whisper Features → UNet → VAE Decoder → Lip Region
Video Frame → Face Detection → Crop → Blend → Output Frame
```
Key components:
- **Audio Processing**: Whisper encoder for phoneme-aligned features
- **Generation**: Latent diffusion in VAE space
- **Blending**: Face parsing for seamless composition
### 3.2 End-to-End Pipeline
```python
# Complete dubbing pipeline
1. Extract audio from video
2. Zen Omni: Translate speech Generate translated audio
3. Zen Dub: Generate lip-synced video
4. Composite: Merge translated audio + lip-synced video
```
### 3.3 Real-Time Performance
| Stage | Latency | Hardware |
|-------|---------|----------|
| Audio Extraction | ~50ms | CPU |
| Speech Translation | ~300ms | GPU (A100) |
| Lip Generation | ~100ms/frame | GPU (V100) |
| Compositing | ~10ms/frame | CPU |
Total pipeline latency: < 500ms for streaming operation.

| JA → EN | 38.7 | 0.82 |
| EN → ZH | 45.1 | 0.86 |
| ZH → EN | 41.2 | 0.83 |
### 6.2 Lip Sync Quality
| Metric | Score |
|--------|-------|
| LSE-D | 7.8 |
| LSE-C | 3.2 |
| FID | 12.4 |
### 6.3 Voice Preservation
Mean Opinion Score (MOS) for voice similarity: 4.2/5.0
## 7. Usage Examples
### 7.1 Speech Translation
```python
from zen_omni import ZenOmniTranslator
translator = ZenOmniTranslator("zenlm/zen-omni")
text, audio = translator.translate_speech(
"japanese_news.wav",
target_lang="en",
preserve_prosody=True
)
```
### 7.2 Video Dubbing
```python
from zen_omni import ZenDubbingPipeline
pipeline = ZenDubbingPipeline(
translator="zenlm/zen-omni-30b-instruct",
lip_sync="zenlm/zen-dub"
)
dubbed_video = pipeline.dub(
"input_video.mp4",
target_lang="en",
output_path="dubbed_video.mp4"
)
```
## 8. Limitations
1. **Speech Output Languages**: Limited to 10 languages for audio generation
2. **Real-Time Streaming**: Requires GPU for acceptable latency
3. **Voice Cloning**: Voice preservation is approximate, not exact cloning
4. **Lip Sync Artifacts**: Extreme head poses may cause artifacts
## 9. Future Work
1. Expand speech output languages
2. Improve voice cloning fidelity
3. Real-time streaming optimization
4. Edge deployment via quantization
## 10. Conclusion
Zen Omni provides a unified solution for speech translation and video dubbing, combining state-of-the-art multimodal understanding with efficient sparse inference. The integration with Zen Dub enables production-ready video localization.
