arXiv:2605.26087v1 Announce Type: cross Abstract: Frontier LLMs now perform strongly across a wide range of physics evaluations, but it is hard to disentangle genuine reasoning from recall of established science. We introduce DiscoverPhysics, an interactive benchmark that asks a LLM agent to discover the laws of motion of a simulated world whose physics deliberately deviates from our own. We construct 22 worlds governed by, among others, screened and fractional-power gravity, multi-species couplings, hidden dark-matter-like particles, non-coordinate-free physics, and time-varying interactions.
The rapid advancement and strong performance of LLMs across various evaluations necessitate new methods to assess their fundamental reasoning capabilities beyond mere recall of existing scientific knowledge.
This benchmark introduces a rigorous way to test LLMs' capacity for true scientific discovery and adaptation to novel physical laws, which is crucial for their deployment in scientific research and autonomous agency.
The ability to distinguish between LLM recall and genuine 'scientific thinking' provides a more accurate metric for AI progress and identifies pathways for developing more robust and generalizable AI systems.

The 'DiscoverPhysics' benchmark provides a standardized, objective measure for LLM scientific reasoning.
This will drive development towards LLMs capable of genuinely novel scientific hypothesis generation and experimentation, accelerating scientific discovery in real-world contexts.
LLM agents could ultimately become autonomous scientists, discovering new fundamental laws and engineering principles with minimal human intervention.
