World Model IndexMethodology
Sources, model categories, metric definitions, and review policy.
Coverage & sources
The index covers interactive worlds, continuous video, video clips, and 3D world generators.
Sources include official papers, repositories, documentation, and hosting rate cards. Profiles distinguish model capabilities from features added by a hosting platform.
Model categories
Interactive worlds
Visual environments controlled through navigation or actions.
Continuous video
Ongoing video or queued clips directed through prompts and images. Update intervals vary by pipeline.
3D worlds
Persistent 3D scenes generated or reconstructed from inputs.
Video clips
Finite clips generated from text or images, priced by output duration.
Prices & performance
Profiles label provider-reported specifications, native and delivered resolution, generation speed, and input latency. Prices use verified USD/hr rates with their billing unit.
Missing rates remain unverified. Self-hosted models require compute; licenses may restrict commercial use.
Index order & ratings
Provider-sourced specifications and prices. Elo scores link to external evaluations.
Default order is editorial. Sort by name, session rate, or output rate; unverified prices appear last. Elo applies to the exact tested model and benchmark. Other entries remain unrated.
Review dates & corrections
Sources were checked on October 15, 2026. Dates change after a completed review. Prices and access may change between reviews.
