PhysMent: An Interactive Approach For LLM Reasoning In Physics Problems

PhysMent is a new benchmark evaluating LLM physical reasoning through interactive, tool-mediated experimentation in a MuJoCo physics simulator.

Unlike static benchmarks, PhysMent requires models to actively discover information by applying forces, querying object states, and modifying geometry. It tests the ability of LLMs to reason about the physical world through iterative interaction rather than just predicting static outcomes.
