LM Fight Arena: Benchmarking Large Multimodal Models via Game Competition

The paper introduces LM Fight Arena, a new benchmark that pits large multimodal models against each other in the fighting game Mortal Kombat II to evaluate real‑time visual understanding and sequential decision‑making. Six leading open‑ and closed‑source models were tested in a controlled tournament where each controlled the same character, ensuring a fair comparison. The framework offers a fully automated, reproducible, and objective assessment of an LMM’s strategic reasoning in a dynamic setting.

Gym-Anything for Robotics: Scaling physical simulations with digital agents

Gym-Anything for Robotics is a framework that uses coding agents to automatically create realistic robotics simulations, addressing the scalability bottleneck of expert-driven simulation design. By selecting tasks based on U.S. GDP data and employing an adversarial creation-audit loop, the authors built RoboWorld, a benchmark of 25 simulations with 25 test and 175 training RL environments. The paper also introduces new techniques—such as in-context learning, privileged teachers, self-assisted learning, and code policies—to improve frontier models, all of which significantly boost performance on the benchmark.
