3DLLM-Mem: Long-Term Spatial-Temporal Memory for Embodied 3D Large Language Model

arXiv — cs.LGThursday, December 18, 2025 at 5:00:00 AM
  • The introduction of 3DLLM-Mem marks a significant advancement in the capabilities of Large Language Models (LLMs) by integrating long-term spatial-temporal memory for enhanced reasoning in dynamic 3D environments. This model is evaluated using the 3DMem-Bench, which includes over 26,000 trajectories and 2,892 tasks designed to test memory utilization in complex scenarios.
  • This development is crucial as it addresses the limitations of current LLMs in planning and acting effectively within multi-room 3D spaces, potentially leading to more sophisticated applications in robotics, gaming, and virtual environments where spatial awareness is essential.
  • The evolution of memory management in LLMs reflects ongoing discussions in the AI community regarding the balance between memorization and learning, safety alignment, and the integration of non-text modalities. As LLMs become more capable, the implications for privacy, data handling, and the ethical use of AI technologies continue to be paramount.
