tinywmcraft: train a world model in under 10 minutes for $0.1 of compute, and play it

tinywmcraft is a 13.9-parameter world model of Craftax-Classic learned entirely from scratch using pixels and actions. Trained in under 10 minutes on a single A100 GPU for approximately $0.10 of compute, it generates subsequent frames, rewards, and episode endings, allowing users to play directly inside the imagined model.
