+
+```python
+from zen_omni import ZenOmniTranslator
+from zen_dub import ZenDubPipeline
+
+# Initialize components
+translator = ZenOmniTranslator("zenlm/zen-omni")
+lip_sync = ZenDubPipeline("zenlm/zen-dub")
+
+# Full dubbing pipeline
+def dub_video(video_path, target_language="en"):
+    # 1. Extract audio from video
+    audio, frames = extract_video(video_path)
+
+    # 2. Translate speech with Zen Omni
+    translated_audio = translator.translate_speech(
+        audio,
+        target_language=target_language,
+        preserve_prosody=True
+    )
+
+    # 3. Generate lip-synced video with Zen Dub
+    dubbed_video = lip_sync.generate(
+        frames=frames,
+        audio=translated_audio,
+        fps=30
+    )
+
+    return dubbed_video
+
+# Run pipeline
+result = dub_video("input_japanese.mp4", target_language="en")
+result.save("output_english_dubbed.mp4")
+```

+## Abliteration
+
+Zen Omni 30B weights are derived from an abliterated base model. Abliteration removes
+refusal behavior by identifying and nullifying the "refusal direction" in the model's
+residual stream, as described in
+[Maxime Labonne's methodology](https://huggingface.co/blog/mlabonne/abliteration).
+
+**Method**: Directional ablation on the residual stream across all layers
+**Source**: Zen MoDE (Mixture of Distilled Experts) architecture base
+**Effect**: Removes refusal behaviors while preserving all other capabilities
+**Identity layer**: Zen identity added via system prompt — full LoRA fine-tuning planned
+
+Abliteration is a feature, not a limitation. It enables unrestricted research,
+security testing, and applications where safety guardrails are managed at the
+application layer rather than baked into model weights.
+
