# SpatialBench

Evaluation platform for **"Do LLMs Build Spatial World Models? Evidence from Grid-World Maze Tasks"** (ICLR 2026 Workshop).

Three tasks probe whether LLMs construct internal spatial representations:

| Task | Type | Description |
|------|------|-------------|
| **Maze Navigation** | Planning | Find shortest path from start to goal |
| **Sequential Point Reuse** | Reasoning | Q3 = Q0 — do models reuse earlier computation? |
| **Compositional Distance** | Reasoning | Compose corner→center distances for Q2 |

Models evaluated: Gemini 2.5 Flash, GPT-5 Mini, Claude Haiku 4.5, DeepSeek Chat.
