Tencent Hunyuan releases ExplorationBench to test how AI systems discover rules

Researchers from Tencent Hy, Fudan University, and Tsinghua University released ExplorationBench, a benchmark that tests whether AI systems can discover hidden rules in executable Alien World sandboxes.

Across 10 frontier systems, getting feedback from experiments outperformed thinking alone, with the best run reaching 89.0% after four rounds. The authors note that rankings barely transfer between the two worlds, and the code is listed as coming soon.
