WorldPlay 2

WorldPlay2 is a research interactive world model that generates video of a scene in real time in response to user controls, while keeping the world consistent over long horizons. According to a YouTube review, it is built on Alibaba's Wan 2.2, includes a 4-step turbo model, and has its code released. The project page is titled "Extending Real-Time Interactive World Models in Control and Horizon".

It uses a factorized hybrid control interface. Frame-aligned action control covers camera pitch and yaw, discrete forward/backward and lateral movement, camera perspective and jump. Structured semantic control splits a caption into scene, character and event fields, so appearance, identity and dynamic events (for example igniting a stove) can be controlled separately.

For long-horizon consistency, a learnable history compressor turns past context into compact memory tokens (sink, compressed and adjacent temporal tokens), cutting sequence length by about 32x. A distillation method called Stable Forcing (few-step initialization plus full-rollout replay) trains an autoregressive few-step student from a bidirectional teacher.
