January 26, 2026Explore more design options faster - with tighter control over your input in Fenestra.

You can now generate architectural renders faster, with tighter control over your input - without burning through credits!
Flux Klein is now live on Fenestra, designed for rapid sketch-to-render workflows where speed, structure, and iteration matter.
Available in 4b and 9b, it gives you a simple way to balance creative exploration with precise adherence to your drawings.
What this unlocks:
- Faster renders for early concepts and client visuals
- Megapixel control to dial between loose exploration and strict input accuracy
- Lower credit usage so you can test more directions
- Reliable sketch → render with strong spatial intent
- Illustrative or realistic outputs, depending on what the project needs
Examples:




- AI Tools for Architects & Interior Designers see what’s possible in Fenestra
- Sketch → Render in Minutes A core workflow
- Create Consistent Views Multiple views from one image

Try it yourself in Fenestra.
