Spatial intelligence complements linguistic intelligence for 3‑D reasoning
  • Spatial intelligence lets an agent infer geometry, affordances, and physical constraints directly from visual input.
  • Linguistic intelligence excels at abstract reasoning, planning, and knowledge retrieval.
  • Combining both yields systems that can understand a scene (spatial) and explain it (language).
  • World Labs’ Marble exemplifies this hybrid approach by taking textual prompts and producing editable 3‑D worlds.

Spatial intelligence is the capability that allows you to reason, understand, move and interact in space. It is complementary to linguistic intelligence. Fei-Fei Li
The AI field is inspired by human intelligence, which is multi‑intelligent, including spatial. Fei-Fei Li

From this concept

Spatial Intelligence vs. Language Intelligence

The conversation distinguishes spatial reasoning--understanding, moving, and interacting in 3-D space--from linguistic processing. Humans are born with high-bandwidth visual perception, while language is a comparatively low-bandwidth, symbolic channel. Building AI that matches human spatial acuity requires models that go beyond token-by-token prediction.
