- 4Context Forcing is a distillation method that preserves the model's capacity to use long-range information
Details
HY-World 1.5 is an advanced AI system that generates fully playable, real-time 3D virtual environments. It addresses the trade-off between speed and memory that limits current methods by using several key innovations. The Dual Action Representation enables precise camera control based on user inputs, while the Reconstituted Context Memory dynamically rebuilds context from past frames to maintain long-term geometric consistency. WorldCompass is a novel Reinforcement Learning framework designed to directly improve the action-following and visual quality of the long-horizon, autoregressive video model. Context Forcing is a distillation method that aligns memory context between the teacher and student models, preserving the student's capacity to use long-range information while enabling real-time speeds. Together, these advancements allow HY-World 1.5 to generate high-quality, interactive 3D worlds at 24 FPS with superior consistency compared to existing techniques.
