Four models live in Lumen's Image Generator. Pick by what you're making:
- Flux 1.1 Pro — photorealism, sharp typography, perfect text rendering. The default workhorse.
- Imagen 3 — best faces, best text. Pick for portraits and posters.
- Stable Diffusion 3.5 — open and flexible, the cheapest. Pick for high-volume drafting.
- Midjourney v7 — art direction, painterly look. Pick for editorial, cover art, anything where the look matters more than the realism.
Style references
Upload a single image that captures the visual world you want — colour palette, lighting, materials. Lumen will pull from it without copying it.
Character references
Upload a single image of a face or character. Lumen keeps that character consistent across every variation.
Aspects, count, seed
Default count of 4 gives you good variety. Lock the seed once you find a generation you like and re-render variations — same seed, slightly different prompts.
