A world model is an AI system that learns a predictive representation of how an environment changes over time. It can use observations, actions, or language to estimate future states and possible outcomes before an agent acts. World models support planning in model-based reinforcement learning, robotics, embodied AI, autonomous driving, and interactive simulation. This site catalogs these systems with model records, research papers, benchmark context, and source links.

PixVerse R1 is a real-time interactive world model that introduces multi-user shared worlds, a first in the field. Users can enter AI-generated environments as personalized avatars and explore alongside others through a continuous shared livestream, with no session time limits. The model generates interactive worlds from text or image prompts while maintaining real-time consistency for multiple simultaneous participants. R1 represents a significant shift from single-user world models toward collaborative, persistent AI-generated environments.
PixVerse R1 is a real-time interactive world generation with multi-user participation developed by PixVerse in 2026 for interactive entertainment.

This model page synthesizes primary papers, official model pages, benchmark evidence, and related world-models.io context into a reference resource.
Each editorial page is assembled from primary sources, normalized into extractable summaries, checked for factual drift, and reviewed before publication or major refreshes. Last reviewed: 2026-04-10.
Pages are refreshed when a new paper, benchmark, release, architecture update, or stronger primary source materially changes the answer a reader or AI system should retrieve.
Each page links back to relevant primary sources and keeps a stable canonical URL so readers can verify claims, trace context, and reference the most up-to-date version. See the editorial policy.
