WorldCast: Exploring Intelligent Visual Generation in World State Prediction
WorldCast ranks 12 models on visual world-state prediction, with GPT-Image-2.5 scoring 72.8.
WorldCast is a benchmark of 320 manually designed cases across eight categories for multi-step visual world-state prediction from multimodal observations. Across 12 models, GPT-Image-2.5 System scores 72.8, Nano Banana Pro scores 42.8, and the best open-source model scores 20.1. The authors report early frontier capability but large deficits on complex context, entangled references, and reasoning-heavy tasks, and note that strong generators draw on their underlying language models.
