+
+#### OAuth Scope Limitations ⚠️
+
+**Common Issue**: Gradio OAuth tokens often have **limited scopes** by default:
+- ✅ **"read" scope**: Can access user profile, model info
+- ❌ **"inference" scope**: Cannot access model generation APIs
+- ❌ **"write" scope**: Cannot perform model inference
+
+**System Behavior**:
+- **High-scope token**: Uses advanced models (Qwen, FLAN-T5) → 30%+ GAIA performance
+- **Limited-scope token**: Uses SimpleClient fallback → 15%+ GAIA performance  
+- **No token**: Uses SimpleClient fallback → 15%+ GAIA performance
+
+**Detection & Handling**:
+```python
+# Automatic scope validation
+test_response = requests.get("https://huggingface.co/api/whoami", headers=headers)
+if test_response.status_code == 401:
+    # Limited scopes detected - use fallback
+    oauth_token = None
 ```
