New benchmark tests LLM physical reasoning via interactive physics simulation

Researchers have introduced PhysMent, a new benchmark designed to evaluate the physical reasoning capabilities of large language models (LLMs) through interactive experimentation. Unlike static benchmarks, PhysMent requires LLMs to actively engage with a MuJoCo physics simulator by applying forces, querying states, and modifying the environment before answering questions. While current models show competence in qualitative tasks, their performance significantly drops on quantitative problems demanding precise, multi-step experimental procedures, with most models scoring below 30% on challenging single-concept tasks.

    PhysMent: An Interactive Approach For LLM Reasoning In Physics Problems

    arXiv:2609.13152v1 Announce Type: new Abstract: Large language models (LLMs) perform strongly on static science benchmarks, yet their ability to reason about the physical world through active experimentation remains poorly understood. We introduce PhysMent, a benchmark that evalu…
