GeoGramBench: Benchmarking the Geometric Program Reasoning in Modern LLMs

GeoGramBench is a tailored benchmark dataset designed for evaluating the geometric spatial reasoning capabilities of large language models (LLMs) over procedural programmatic code. The dataset introduces a novel task, Program-to-Geometry, that requires models to transform programmatic drawing code into abstract geometric reasoning for problem-solving.

Features of GeoGramBench

• 500 Curated Problems: Each sample includes procedural drawing code and associated geometry reasoning problems. These problems are rigorously curated to ensure quality, fairness, and diversity.
• Taxonomy-Based Evaluation: Problems are categorized into three difficulty levels:
  • Primitive Recognition: Basic geometric problems requiring direct recognition of a few elements.
  • Local Relation Composition: Involves reasoning about relationships between multiple geometric components.
  • Global Abstract Integration: Complex problems requiring global spatial synthesis, parameterization, or 3D reasoning.
• Six Subtypes: Problems span six mathematical subfields: Angle, Length, Area, Volume, Ratio, and Count, supporting fine-grained diagnostics.

Dataset Composition

Subtype	Primitive	Compositional	Abstract
Angle	22	20	7
Length	25	88	20
Area	26	89	46
Ratio	14	51	4
Count	15	31	15
Volume	0	0	27

Benchmark Highlights

• GeoGramBench differs from traditional math benchmarks by emphasizing the symbolic-to-spatial abstraction capabilities of LLMs, leveraging procedural code expressed in formats such as Asymptote.
• Initial evaluation using 17 state-of-the-art LLMs revealed substantial gaps, particularly for higher abstraction tasks:
  • Models achieved less than 50% accuracy on the most challenging Global Abstract Integration category.
  • Even advanced models struggle to bridge procedural code with reliable spatial reasoning.
