About Marble 1.0 Draft

Marble 1.0 Draft is the quick, low-commitment mode of World Labs' Marble world model. It produces an early version of a 3D world from a text description or visual input, so you can judge layout and direction before running a full generation. Its documented draft step takes about twenty seconds, which makes it suited to trying many prompts rather than delivering a final scene.

Where it works well

Gives a fast first look at a world, which suits comparing several prompts or reference images in a row.
Takes the same kinds of starting points as full generation, from a text prompt to images and panoramas.
Helps settle layout, setting, and mood before you spend a full generation on a finished world.
Produces the same set of output file types as the standard model, so a draft can be inspected in familiar tools.

When to choose another model

A draft is an early exploration, not a finished scene, so detail and polish fall short of the full Marble models.
It stays on the 1.0 generation and does not include the lighting and artifact improvements of Marble 1.1.

Help me create with marble-1.0-draft using world-generation at /v1/worlds/generations. Show the result, status, and cost.

Use cases

Prompt iteration
Run a string of variations on a setting, keep the two or three that read well, and only then generate the full world.
Layout checks
Confirm that a reference photo or sketch turns into the room arrangement or street shape you had in mind.
Client previews
Show a rough explorable space early in a discussion, before any budget goes into a polished version.

Prompt examples

An open-plan loft with a spiral staircase and a long window wall, evening light, sparse furniture.

A desert canyon trail with a rope bridge and a distant camp, midday haze.

Use this floor-plan sketch as the starting point and give me a rough walkable version.

FAQ

What is Marble 1.0 Draft for?

It is for exploring ideas quickly. You get an early version of a world to check composition and direction, then decide whether the concept deserves a full generation with a standard Marble model.

How long does a draft take?

World Labs' Marble documentation describes creating a draft from any input as taking roughly twenty seconds. Actual time on the page below reflects measured latency, which can differ with load.

Is a draft good enough to ship?

Usually not. Treat it as a sketch: it shows what the scene will roughly be. For a deliverable asset, regenerate with Marble 1.0, 1.1, or 1.1 Plus.

What can I feed into Marble 1.0 Draft?

A text description, a single image, a panorama, several images of the same scene, or video, following World Labs' documented input types for world generation.

Does Marble 1.0 Draft have a newer version?

The Marble 1.1 line added a standard and a Plus model on 2 April 2026, while draft remained available under its 1.0 name. Pair the draft with the full model you intend to finish on.

How much does Marble 1.0 Draft cost?

On TokenLab, Marble 1.0 Draft costs $0.12-$0.20 per request. The pricing table above shows the full breakdown. Rates depend on the billing unit, specification, and usage. Compare matching conditions in the model's detailed pricing; a single rate does not determine the total cost.
