GI discovered their world model, trained on game footage, could generate a realistic camera shake during an in-game explosion—a physical effect not part of the game's engine. This suggests the models are learning an implicit understanding of real-world physics and can generate plausible phenomena that go beyond their source material.

Historically, computer vision treated 3D reconstruction (capturing reality) and generation (creating content) as separate fields. New techniques like NeRFs are merging them, creating a unified approach where models can seamlessly move between perceiving and imagining 3D spaces. This represents a major paradigm shift.
Static benchmarks are easily gamed. Dynamic environments like the game Diplomacy force models to negotiate, strategize, and even lie, offering a richer, more realistic evaluation of their capabilities beyond pure performance metrics like reasoning or coding.
A Rice PhD showed that training a vision model on a game like Snake, while prompting it to see the game as a math problem (a Cartesian grid), improved its math abilities more than training on math data directly. This highlights how abstract, game-based training can foster more generalizable reasoning.
Large language models are insufficient for tasks requiring real-world interaction and spatial understanding, like robotics or disaster response. World models provide this missing piece by generating interactive, reason-able 3D environments. They represent a foundational shift from language-based AI to a more holistic, spatially intelligent AI.
GI's founder argues game footage is a superior data source for spatial reasoning compared to real-world videos. Gaming directly links visual perception to hand-eye motor control ("simulating optical dynamics with your hand"), avoiding the information loss inherent in interpreting passive video, which requires solving for pose estimation and inverse dynamics.
Instead of replacing entire systems with AI "world models," a superior approach is a hybrid model. Classical code should handle deterministic logic (like game physics), while AI provides a "differentiable" emergent layer for aesthetics and creativity (like real-time texturing). This leverages the unique strengths of both computational paradigms.
While a world model can generate a physically plausible arch, it doesn't understand the underlying physics of force distribution. This gap between pattern matching and causal reasoning is a fundamental split between AI and human intelligence, making current models unsuitable for mission-critical applications like architecture.
Current multimodal models shoehorn visual data into a 1D text-based sequence. True spatial intelligence is different. It requires a native 3D/4D representation to understand a world governed by physics, not just human-generated language. This is a foundational architectural shift, not an extension of LLMs.
A Harvard study showed LLMs can predict planetary orbits (pattern fitting) but generate nonsensical force vectors when probed. This reveals a critical gap: current models mimic data patterns but don't develop a true, generalizable understanding of underlying physical laws, separating them from human intelligence.
When analyzing video, new generative models can create entirely new images that illustrate a described scene, rather than just pulling a direct screenshot. This allows AI to generate its own 'B-roll' or conceptual art that captures the essence of the source material.
