Summary
A GitHub project called tinywmcraft, by Maharishiva, trains a 14M-parameter world model that learns 2D Minecraft (Craftax-Classic) from pixels and actions alone, then generates playable frames one action at a time with no game engine. It runs on one A100 in under 10 minutes for about $0.10 of compute.
