+## ⚙️ Advanced Configuration
 
 ### Change Models
 Edit `app.py` to use different models:
+
 ```python
-# Use larger BLIP model
+# Use larger BLIP model for better quality
 caption_model = BlipForConditionalGeneration.from_pretrained(
-    "Salesforce/blip-image-captioning-large"
+    "Salesforce/blip-image-captioning-large"  # 990MB, better quality
+)
+
+# Use larger CLIP model
+clip_model = CLIPModel.from_pretrained(
+    "openai/clip-vit-large-patch14"  # 1.7GB, more accurate
 )
 ```
 
-### Customize Interface
+### Customize Interface Style
 Modify `custom_css` in `app.py`:
+
 ```python
 custom_css = """
 #title {
-    background: linear-gradient(90deg, #YOUR_COLOR 0%, #YOUR_COLOR 100%);
+    background: linear-gradient(90deg, #FF6B6B 0%, #4ECDC4 100%);
+    font-size: 3.5em;
 }
 """
 ```
 
+### Adjust Generation Parameters
+Control model behavior:
+
+```python
+# Generate longer captions
+out = caption_model.generate(**inputs, max_length=100)
+
+# More accurate but slower VQA
+out = vqa_model.generate(**inputs, max_length=50, num_beams=5)
+```
+
 ## 🐛 Troubleshooting
 
-**Issue: Models downloading slowly**
+### Common Issues
+
+**Models downloading slowly**
 ```bash
-# Set cache directory
-export HF_HOME=/path/to/storage
+# Set cache directory to a location with more space
+export HF_HOME=/path/to/large/storage
+python app.py
 ```
 
-**Issue: Out of memory**
+**Out of memory error**
 ```python
-# Use CPU only
+# Add at the start of app.py
+import torch
+torch.cuda.empty_cache()
+
+# Or force CPU usage
 device = "cpu"
 ```
 
-**Issue: Port already in use**
+**Port already in use**
 ```bash
+# Use different port
 python app.py --server-port 8080
 ```
 
+**Space build failing**
+- Check `requirements.txt` for correct package versions
+- Verify all files are uploaded correctly
+- Check build logs in Space settings
