Benchmark-driven evaluation demonstrates language model performance in simulated embodied reasoning tasks, suggesting strengths and limitations.

The central aim is to evaluate the effectiveness of large language models in embodied reasoning tasks via a structured benchmarking process.
Utilized large language models (GPT-4.1, GPT-4.1-mini, GPT-5-mini) for embodied reasoning tasks.
Engaged in four stages: goal interpretation, subgoal decomposition, action sequencing, and transition modeling.
Executed tests in BEHAVIOR and VirtualHome simulators with specific action vocabularies and symbolic state representations.
Evaluated performance according to a standard protocol on a public leaderboard.
Ranked eighteenth overall on the public leaderboard with a score of 57.92.
Achieved a score of 68.88 in the BEHAVIOR simulator and 46.96 in the VirtualHome simulator.
Observations indicate both strengths and limitations in using large language models for embodied reasoning.
