Researchers have introduced PERSIST, a new world model paradigm that explicitly represents 3D environment state rather than learning 3D consistency implicitly from video data. The approach maintains persistent spatial memory and geometric consistency across extended generation horizons, addressing a core limitation of existing interactive video models that lack explicit 3D representations.

World Labs, the AI startup founded by Fei-Fei Li, has raised $1 billion in new funding to develop spatial intelligence—AI systems capable of understanding and operating in three-dimensional physical environments. The capital will fund the development of world models, a class of AI architecture designed to reason about spatial relationships and physical interactions.
