MultiWorldBench: can independently controlled views describe one shared world
The authors propose MultiWorldBench, a diagnostic Minecraft benchmark for testing whether independently controlled views in a multi-player world model stay consistent with one single persistent shared world; it contains 495 case configurations, seven task suites and ten capabilities.
Why it matters: With 495 configurations, the paper compares three generative world models against the reference Engine GT on ten capabilities, and the score gaps show where the current weaknesses lie.
