TangramPuzzle: Evaluating Multimodal Large Language Models with Compositional Spatial Reasoning

TangramPuzzle is introduced, a benchmark comprising 668 validated configurations and 1,336 instances for evaluating compositional spatial reasoning under geometric constraints, and the Tangram Construction Expression is formulated to encode tangram configurations with machine-verifiable geometric specifications.

From Atomic to Agentic: Towards Interpretable Evaluation of LLMs'Agentic Mathematical Capabilities

Experiments reveal that models with similar end-to-end accuracy can exhibit markedly different agentic capability profiles, demonstrating that process-level evaluation is crucial for interpreting the true potential of LLMs and guiding the development of next-generation mathematical agents.
