This research introduces the first vocabulary-free 3D instance segmentation system that can identify objects without predefined vocabulary constraints, enabling true open-ended scene understanding.

• Eliminates the need for predetermined object categories or vocabulary prompts
• Leverages large language models to assist in scene interpretation
• Enables natural language queries like "List all objects in this scene"
• Outperforms existing open-vocabulary approaches in 3D instance segmentation

Security Implications: This technology significantly enhances security systems by allowing more flexible and comprehensive scene monitoring. Security applications can detect and identify unusual or unexpected objects without being limited to predefined categories, improving threat detection capabilities.
