Overview
What is Flux 2?
Flux 2 is an open-weights image model that Mage runs on its own GPUs as Flux 2 Dev, so there is nothing to install and no GPU to rent.
It thrives on long prompts with several conditions, and it edits or combines a few input images in one generation.
Samples
Made with Flux 2
Generated on Mage with Flux 2. A prompt under a sample is the exact prompt that made it.
Editorial product still lifePrompt: A weathered brass compass resting on a folded nautical chart on an oak desk. Morning light comes through a round porthole and casts a soft ellipse across the paper. A coil of hemp rope and a pair of reading glasses sit at the edge of the frame, with dust motes floating in the beam. Editorial product photography, 50mm lens, f/2.8.
Overhead food flat layPrompt: Overhead flat lay of a bowl of ramen on a dark slate table: glossy broth, a halved soft-boiled egg with a jammy yolk, three slices of chashu, a sheet of nori, sliced scallions, and chopsticks resting on a small ceramic rest to the right. Steam rises from the bowl. Warm tungsten key light from the left, deep shadows on the right.
A detailed interiorPrompt: A cozy reading nook built into a bay window during a thunderstorm. Rain streaks the glass, a knitted blanket hangs over the cushion, a stack of hardback books leans against the wall, and an orange cat sleeps curled up in the corner. A brass floor lamp glows amber. Photoreal interior photography, wide angle.

Prompt guide
How to prompt Flux 2
Tips that work on this model. The prompts under the samples above are good places to start.
Tips
- Write in full sentences: Flux 2 reads a paragraph better than a list of tags.
- Describe the scene in layers: the subject, the supporting objects, the background, then the light.
- State the light direction and color (warm tungsten key light from the left).
- Add the photographic detail last: the lens, the aperture, the look.
- To edit, attach the image and describe the change; attach several to combine them.
