World Models That Evolve While Frozen, Test-Time Memory That Lifts Agent Planning
World models promise long-horizon LLM agents the gift of foresight, yet a wrong prediction often does more harm than none. WorldEvolver improves without touching a single weight, revising only the memory it consults at deployment time to sharpen both prediction and planning at once.
Resolving the Structural Dilemma of Song Generation, Aesthetics-Guided Training Closes the Gap with Commercial Systems
Full-length song generation is trapped between keeping vocals and accompaniment in sync and rendering each track's acoustic detail. LeVo 2 reframes this trade-off as a question of hierarchy and folds musical taste directly into the training schedule, pushing open-source models toward the quality of closed commercial systems.
VLK Generates Robot Training Data From the Inside Out, Easing Humanoid Learning's Tightest Bottleneck
Teaching a humanoid to see, listen, and move its whole body at once requires a kind of synchronized data that simply does not exist at scale. VLK sidesteps the problem by reconstructing real rooms with Gaussian Splatting, scripting robot behavior inside them, and rendering the first-person view afterward — producing 48,000 training trajectories without a single human in the loop.
