Google introduced Genie 4 — as a world model for creating interactive experiences with AI. The Verge AI notes four changes: more realistic worlds, real-time editing of the experience via natural-language prompts, sound generation, and longer-running narratives.

Genie 4 creates experiences lasting about two minutes. The previous Genie 3 was claimed to last about one minute. This could make such interactive scenes more suitable for demonstrations and sequential interaction, but the source does not provide independent quality measurements or usage examples.

The report is based on a synopsis of The Verge AI publication, not the full text of the material or independent primary confirmation. Therefore questions remain about the availability of Genie 4, the startup requirements, and how well the model maintains realism when changes are made in real time.
