+### 2. HTML Integration
+
+```html
+<!DOCTYPE html>
+<html>
+<head>
+    <title>Janus WebGPU Demo</title>
+    <script type="module">
+        import { AutoProcessor, AutoModelForCausalLM } from 
+            'https://cdn.jsdelivr.net/npm/@huggingface/transformers@3/dist/transformers.min.js';
+
+        async function loadModel() {
+            const model = await AutoModelForCausalLM.from_pretrained(
+                'Zhare-AI/janus-pro-7b-webgpu',
+                { device: 'webgpu', dtype: 'q4f16' }
+            );
+
+            console.log('Model loaded!');
+        }
+
+        loadModel();
+    </script>
+</head>

+    <h1>Janus-Pro-7B WebGPU</h1>
+    <p>Check browser console for loading progress.</p>
+</body>
+</html>
+```
+
+### 3. Production Considerations
+
+- **CDN**: Host model files on a CDN for global distribution
+- **Caching**: Implement proper cache headers for model files
+- **Progressive Loading**: Load model components as needed
+- **Error Handling**: Graceful fallbacks for unsupported browsers
+- **Memory Management**: Clean up resources when done
+
+## Limitations
+
+### Current Limitations
+
+- **Browser Support**: Limited to WebGPU-compatible browsers
+- **Model Size**: Still requires significant download (4GB)
+- **First Load**: Initial model download takes time
+- **Memory Usage**: Requires substantial GPU memory
+- **Image Generation**: Slower than dedicated hardware
+
+### Known Issues
+
+- Firefox WebGPU support is experimental and may have issues
+- Safari WebGPU support is in beta with limited functionality
+- Very large images may cause memory issues
+- Some complex prompts might not generate as expected
+
+## Technical Details
+
+### Quantization Strategy
+
+- **Weights**: 4-bit unsigned integer quantization
+- **Activations**: 16-bit floating point precision
+- **Calibration**: Post-training quantization without calibration dataset
+- **Optimization**: Weight-only quantization to minimize quality loss
+
+### ONNX Conversion
+
+The model was converted using a custom pipeline:
+
+1. **Model Loading**: Load original Janus-Pro-7B with trust_remote_code
+2. **Component Extraction**: Separate embedding, vision, language, and generation heads
+3. **Architecture Simplification**: Reduce complexity for ONNX compatibility
+4. **Quantization**: Apply q4f16 quantization for WebGPU optimization
+5. **Validation**: Comprehensive testing with transformers.js
+
+### WebGPU Optimizations
+
+- **Operator Support**: All operations compatible with ONNX Runtime WebGPU
+- **Memory Layout**: Optimized tensor formats for GPU efficiency
+- **Compute Shaders**: Leverages modern GPU compute capabilities
+- **Pipeline Optimization**: Minimized CPU-GPU memory transfers
