Facts checked September 4, 2026
Quick take
World Labs' public API model for turning text, images, panoramas, multi-view sets, or video into large explorable 3D worlds and spatial assets.
The API and Marble app use separate credit pools. Paid users should also review and configure the available model-training opt-out before uploading proprietary assets.
The public conversational-character surface of Runway's General World Model, creating realtime visual personas from one reference image.
Plan around session limits and explicitly govern voice rights, reference images, transcripts, recordings, knowledge documents, and external tools.

How to choose
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
World Labs' paid-user terms allow users to opt out prospectively from use of user content for model training. Free-account terms differ; review the current account settings and contract before sending proprietary spatial data.
Provider and API links
Data handling depends on the Runway plan and agreement. Review retention, recordings, transcripts, voice rights, and knowledge-base handling before deploying a customer-facing character.
