World Play 2 drops a real-time world generator with long-term memory
World Play 2 just open-sourced an interactive world model that lets you roam and interact with characters and objects in real time. Instead of degrading over long horizons, it compresses past events into memory tokens to keep environments consistent even when you leave and return. It offers a 4-step Turbo version, though the full unquantized model weighs 69GB.
