Hi everyone!

World Labs has officially opened up Marble's capabilities with the launch of the World API.

This enables developers to generate explorable 3D worlds from text, images, and video directly within their applications. There are already many interesting use cases emerging.

Really like their vision:

As world models continue to evolve, we see a future where:

  • Worlds are generated as easily as words and images

  • Spatial intelligence becomes a shared layer across creative tools and physical AI systems

  • Humans and agents can reason, interact, and collaborate inside generated spaces

The World API is our first step toward making that future programmable, and it's available today.

Whooo! This is an amazing product and I'm so happy to see them launch. Discovered World Labs through one the founders TED AI talk in vienna, and got hooked :) Good luck!

Marble feels like a big step forward for programmable 3D worlds 🚀 — especially generating persistent environments from a single prompt or image. Opening this up via the World API is a bold move.

Quick question: how do you handle consistency and object persistence when developers iteratively update the same world through multiple prompts or API calls?

Congrats on the launch 👏
