What changed

World Labs' April 2, 2026 Marble release notes added Marble 1.1 and Marble 1.1 Plus, while keeping Marble 1.0 and Marble 1.0 Draft available as legacy options.

Context summary

World Labs added Marble 1.1 and Marble 1.1 Plus across Marble and the World API, introducing a larger-world tier with dynamic sizing and explicit per-model pricing.

Why visitors should care

This is a real product and API-surface change, not just fresh marketing copy. It gives Marble a clearer versioned model story for both creators and developers, and it adds a concrete comparison-relevant shift against other world-model surfaces: World Labs now publicly distinguishes a standard quality tier from a larger-world tier with variable generation cost.

Official release notes and documentation

Treat this as a documented Marble and World API model rollout. It is stronger than a teaser, but the docs still describe model behavior, credits, and defaults more clearly than broad production guarantees.

FAQ

Before you comment

A compact guide to source confidence, category boundaries, and reader participation before adding a note.

Definition

What does World Models Watch count as a world model?

The site tracks systems that model environments, actions, spatial structure, or persistent simulated state. Pure text chatbots and ordinary video generators are only included when they provide a clear bridge toward interactive or physical world modeling.

Category boundary

Why do some AI video systems appear on a world-model site?

Video models are included only when they help explain the path from generated clips to controllable spaces, physics-aware prediction, or agent-ready simulation. The site keeps that distinction explicit so video generation is not overstated as a finished world simulator.

Editorial policy

How does the site decide whether a release is reliable enough to list?

Primary sources carry the most weight: official product pages, research posts, papers, documentation, code repositories, and company announcements. Secondary media can be referenced, but it stays labeled as reported or adjacent unless independently confirmed.

Community

What should readers post in comments?

Useful comments add source links, corrections, release-status notes, comparison questions, or concrete reader context. Comments are public immediately, so readers should avoid private information and unsupported promotional claims.
