 ### 3. Interactive Testing (`interactive.py`)
 - **Real-time testing**: Take screenshots and visualize model predictions
 - **Commands**: 
-  - Type instruction → screenshot + test all models
-  - `screenshot` → take screenshot without prediction
+  - Type instruction → test all models on last screenshot
+  - `screenshot` → take screenshot
   - `models` → list available models

-## Metrics Tracked
-
-- **Accuracy**: Percentage of clicks within bounding boxes
-- **Timing**: Average, min, max prediction times
-- **VRAM Usage**: Maximum and average GPU memory usage
-- **Per-sample Results**: Detailed breakdown for debugging

-## Architecture
-
-The benchmark system is designed for:
-- **Modularity**: Easy to add new models and benchmarks
-- **Flexibility**: Works with any iterator of dicts with `image`, `bbox`, `instruction` keys
-- **Performance**: VRAM tracking and timing analysis
-- **Visualization**: Automatic generation of prediction visualizations
