Core Innovation: Closing the Perception-Action Loop
Perception-Action Loop Foundation for Embodied Spatial IntelligenceESI-BENCH moves beyond passive observations by recasting the observer as an actor, requiring agents to actively acquire observations and reason about how they change with actions. This active process is crucial for uncovering hidden physical properties and solving complex spatial tasks, leading to more robust and capable AI.

Active Exploration vs. Passive Baselines (Gemini 3.1 Averages)
| Paradigm | Average Accuracy (%) |
|---|---|
| Passive Single-View | 42.5% |
| Passive Multi-View | 39.3% |
| Active Exploration | 56.9% |
| Ground-Truth Passive | 75.1% |
Active exploration demonstrates a substantial gain over passive sensing, with Gemini 3.1 improving average accuracy from 42.5% (Passive Single-View) to 56.9%. Interestingly, Passive Multi-View shows a slight degradation compared to Passive Single-View, highlighting that simply increasing observation quantity without selective action often adds noise rather than signal. The "Ground-Truth Passive" reveals the upper bound if perception were perfect given optimal views.
Action Blindness Dominates Perceptual Blindness
GPT-5: 42.5% Active vs 95.0% GT Passive Performance Gap in Rigid ContainmentFor many tasks, the primary bottleneck is action selection, not perception. Models often fail to achieve optimal performance even with ground-truth views, indicating a struggle to choose informative actions. This 'action blindness' leads to poor observations and cascading errors, even when visual perception itself is adequate.
Case Study: Imperfect 3D Reconstruction
While perfect 3D representations significantly boost reasoning on depth-sensitive tasks, imperfect reconstructions can actively degrade performance. Noisy or corrupted 3D data distorts spatial relations and leads to errors like object duplication (over-counting), object hallucination (spurious proposals), and spatial-relation corruption (inaccurate depth estimates). This highlights a critical need for uncertainty-aware 3D reconstruction for robust embodied AI.
| Task | 2D Gemini 3.1 | GT 3D + Gemini | VGGT + Gemini (Imperfect 3D) |

| Geometric Configuration | 27.5% | 70.8% | 9.9% |
| Counting w Occlusion | 3.3% | 33.3% | 0.0% |
The Metacognitive Gap: Knowing When You've Seen Enough
Human View Diversity: 71.8% vs. GPT-5: 39.2% Difference in Seeking Diverse EvidenceModels exhibit a critical metacognitive gap: they commit prematurely with high confidence, anchor to first impressions, and seek confirmation rather than falsifying viewpoints. Unlike humans, models often fail to revise beliefs when contradicted, demonstrating a fundamental absence of belief updating. This gap cannot be closed by better perception or more embodied interaction alone, requiring advances in epistemic calibration.
Case Study: Human-Level Spatial Reasoning
Humans dramatically outperform models in active exploration by instinctively knowing what to look for and when to stop, exhibiting stronger epistemic caution and belief revision. For example, in Material Transparency, humans achieve 93.6% active accuracy versus Gemini 3.1's 52.3%, even when given fixed observations (Ground-Truth Passive), human scores are significantly higher. This gap underscores the need for AI systems to develop human-like capabilities in strategic exploration and belief management.
