FAQ
What is an AI world generator?
It turns text or images into a spatial scene you can explore. Worlds here use World Labs Marble; images and videos are separate tools in the studio.
Can I play Google Genie 4 here?
Not yet. Genie 4 is listed as Coming soon. Join the waitlist for updates; worlds on this site currently use World Labs Marble. No access date or early-access benefit is promised.
Is it free?
Eligible verified accounts receive 30 free credits, enough for a 20-credit Marble Draft. Marble 1.1 costs 100 credits at the current catalog price. Check the studio for current costs before submitting.
Which file formats can I export?
World outputs include SPZ, a 360° panorama and a collider GLB. PLY and high-quality GLB are available through export options. Paid download rights apply; high-quality mesh export requires Pro or Studio and additional credits. Splats need a compatible renderer.
Can I use the worlds commercially?
Paid plans, and credit packs while you have pack credits, include commercial use of your generated outputs, subject to the terms and rights in your inputs. The free plan is for personal use. Community examples remain credited to their original creators; viewing them does not transfer ownership.
How long does generation take, and what happens if it fails?
Marble Draft is estimated at about one minute and Marble 1.1 at about five minutes; queue time and complexity vary. Failed tasks refund the deducted credits to their original batches with their original expiry dates. Progress remains in Library when you close the page.
