Explore 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:

Photoreal sunlit render of a modern timber-and-glass pavilion with a reflecting pond
Pencil line sketch of the modern pavilion house with reflecting pond and gardens

Try it yourself in Fenestra.
