Researchers have developed ACT3D, a novel approach that enables vision-language models (VLMs) to actively explore 3D environments using reinforcement learning. Unlike previous methods, ACT3D learns to navigate and gather visual information from single first-person views, mimicking human exploration without direct supervision on exploration actions. This method significantly improves answer accuracy on 3D benchmarks, outperforming both its base Qwen model and proprietary models like Gemini 3.6 Flash, while also using fewer input frames. AI
IMPACT Enables VLMs to learn effective exploration strategies in 3D environments, potentially improving performance in robotics and embodied AI applications.
