## Choosing a model

If you're just starting out with Marble, we recommend using **Marble 1.1**.

For the largest worlds, **Marble 1.1 Plus** automatically expands its coverage of 3D space to generate bigger worlds when possible.

Marble also offers other models optimized for different workflows, balancing speed, cost, and quality.
