A few weeks ago, we launched Nano Banana in Fenestra. Now we’re adding Seedream 4.0, and we’ll continue bringing you the best-in-class AI models for images, video, and - in the very near future - World Models.

But what is a world model?

A World Model is essentially a model with spatial awareness. Instead of producing only single images, it can generate explorable environments from sketches, prompts, or image inputs. Some use Gaussian Splats, others generate frames on the fly - either way, you can step into spaces that are alive, real-time, and constantly imagined. Incredible tech. Tools like _Marble (World Labs), Genie 3 (Google), _and Luma Labs are really pushing this forward.

Why it Matters

For architects and interior designers, explaining spatial intent to clients has always been a challenge. With World Models, the shift is from showing a render → to letting clients walk inside it.

From Fenestra Today → World Models Tomorrow

• Furniture Swap Today: Swap a sofa or artwork instantly with Nano Banana. Tomorrow: Walk around the sofa in 1:1, move it, or change it live.
• Lighting & Atmosphere Today: Prompt a winter evening or moody night scene. Tomorrow: Step to the window, watch the snow fall, toggle to summer.
• Detail & Mood Today: Zoom into a macro shot of a table setting. Tomorrow: Lean in, inspect textures, and adjust materials in real-time.

When I started Fenestra, the goal was to make spatial AI accessible for architects and designers. We’ve been achieving this with images and video, but the next leap is clear: communicating design at 1:1, without mediation.

How will this work in Fenestra?

• Upload your image or generate one on the fly in Fenestra
• In a single click turn your generated or uploaded image into a spatial experience
• Single click share with a client or team member directly in your browser, explore in full 3D.

The technology isn’t quite at production level yet - but everything we’re building today is laying the groundwork.
