Genie 3 vs Marble
Google DeepMind's Genie 3 and World Labs' Marble are two of the most-discussed world models, but they answer different questions. Genie 3 generates a real-time, explorable video world from a text prompt and keeps it consistent for a few minutes at a time. Marble builds a persistent 3D scene from text, images, video, or panoramas that you can edit and export as real assets. This page compares only what QuantWorlds has independently verified for each — nothing here is estimated.
World Labs has released several Marble versions (1.0, 1.0 Draft, 1.1, 1.1 Plus). This comparison uses Marble 1.1, the current general-purpose release World Labs itself recommends as the default starting point — not the larger-scale "1.1 Plus" variant or the earlier drafts.

"Not verified" means QuantWorlds has not confirmed that fact from a primary source — it is never a stand-in for "no."
What is Genie 3?
A general-purpose world model from Google DeepMind. Given a text prompt, it generates an explorable environment you navigate in real time — DeepMind describes sessions of a few minutes of continuous interaction before consistency degrades. It has no public API and no open-source release; access is through Project Genie.
What is Marble?
A 3D world-generation model from World Labs. It turns text, images, video, or panoramas into a persistent, editable 3D scene, exportable as Gaussian splats or mesh assets for use in Unity, Unreal, or Blender. It has a real API and freemium/paid access tiers.
Access and playability
Both are publicly accessible today, but the shape of access differs. Genie 3 is a research-preview experience with no account tiers disclosed beyond Project Genie itself. Marble is a commercial product: a free tier exists, but generated output only carries commercial rights on the paid Pro/Max tiers or through the API — see Licensing below.
Interaction and real-time generation
Genie 3 is explicitly real-time: DeepMind states it runs at 20-24 fps with fluid interaction. QuantWorlds has not independently verified a real-time claim for Marble — its own materials describe it as generating an editable scene rather than a live, moment-to-moment interactive stream, so that row is recorded as not verified rather than assumed either way.
Developer access
Marble has a documented World API. Genie 3 does not currently have a public API of any kind — access is through the Project Genie interface only.
Open source and licensing
Neither model is open source. Marble's commercial-use terms are tiered by account: Free-tier output stays personal/non-commercial use only; Pro and Max paid tiers, and API access, carry commercial rights under World Labs' Terms of Service. QuantWorlds has not found published commercial-use terms for Genie 3 — that field is recorded as not verified, not as "no."
Which has playable Worlds on QuantWorlds?
Neither, currently, in QuantWorlds' hands-on-verified sense. Genie 3 is linked to Project Genie, which requires a paid Google AI Ultra subscription. Marble is linked to IMAGE-BLASTER, which is a creation toolkit rather than an explorable World. See Playable Worlds for what QuantWorlds has actually confirmed playable elsewhere in the catalogue.
Which should you explore?
If you want to research how an agent might learn inside a live, responsive environment, Genie 3's real-time generation is the more direct fit. If you need a persistent 3D scene you can export, edit, and bring into an existing engine or pipeline, Marble's API, export formats, and engine compatibility make it the more production-oriented option. Neither is a strict upgrade over the other — they verify differently on almost every row above because they're built for different jobs.
