🔑 Enhanced Key Takeaways

• •NavSpace benchmark was constructed using a four-stage pipeline on the Habitat 3.0 simulator with HM3D scenes, stemming from questionnaire surveys to identify six key spatial intelligence categories.[1][3]
• •The benchmark evaluates 22 navigation agents, revealing that open-source MLLMs average below 10% success rate (chance level), proprietary MLLMs like GPT-5 reach up to 14.2%, while navigation models like StreamVLN achieve 19.2%.[1][3]
• •SNav was tested on real-world AgiBot Lingxi D1 quadruped robot across office, campus, and outdoor environments, outperforming NaVid (14%) and NaVILA (6%) in five spatial intelligence categories.[3]

🛠️ Technical Deep Dive

• •NavSpace includes six task categories derived from questionnaire surveys, with 1,228 high-quality trajectory-instruction pairs manually collected.[1][2]
• •Benchmark construction uses a four-stage pipeline: trajectory generation, instruction annotation, validation, and quality filtering on Habitat 3.0 with HM3D scenes.[1][3]
• •SNav's performance gains from ablation-studied instruction-generation pipelines enhancing spatial intelligence, outperforming baselines like NaVid and StreamVLN on both NavSpace and real-robot tests.[1][3]
