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.
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 👏
Marble's persistence is what makes World API useful beyond demos... most generative 3D stays real-time and ephemeral. A programmable endpoint that spits out downloadable assets from text, image, or video opens up actual integration paths. Curious how the Gaussian splat exports hold up in game engines.
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!

Who hunted World API by World Labs?
World API by World Labs was hunted by Zac Zuo. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
