+
+                To get the best results from Qwen2.5-VL, use clear and descriptive prompts
+                that specify exactly what you want to detect.
+
+                **For general object detection, use this comprehensive prompt:**
+
+                ```
+                Detect all objects in the image and return their locations and labels.
+                ```
+
+                **For specific object detection with detailed descriptions:**
+
+                ```
+                Detect the red object that is leading in this image and return its location and label.
+                ```
+
+                **For simple, targeted detection:**
+
+                ```
+                leading blue truck
+                ```
+
+                **Additional effective prompts:**
+
+                ```
+                Find all people and vehicles in this scene
+                ```
+
+                ```
+                Locate all animals in the image
+                ```
+
+                ```
+                Identify traffic signs and their positions
+                ```
+
+                **Tips for better results:**
+
+                - Use descriptive language that clearly specifies what to look for
+                - Include color, size, or position descriptors when targeting specific objects
+                - Be specific about the type of objects you want to detect
+                - The model responds well to both detailed instructions and concise phrases
+                - Results are returned in JSON format with `bbox_2d` coordinates and `label` fields
