The most-askedquestions in the studio.
Not seeing yours? Pricing lives on /pricing and the full Terms are linked in the footer.
Which models are behind the lanes?+
Lumen wraps nine production-grade AI models: one per lane, from fast drafts to 4K finals, editing and image-to-3D. We pick the model that's strongest at each job; you choose a lane and see its credit cost before you render.
Which aspect ratios are supported?+
1:1 for social, 16:9 for landscape / cinematic, 9:16 for vertical social, 4:3 for editorial, 3:4 for portrait. Free to switch per render.
Do you watermark the output?+
No. We add no visible watermark, and you may use your images commercially under our Terms. Some models embed invisible provenance metadata, which we leave in place.
Can I edit a render after it's done?+
Yes. Every asset gets its own Studio Bench: re-render with a new prompt, swap models, run a natural-language edit via Kontext, or upscale 4× via Real-ESRGAN.
Can I upload a reference image?+
Yes, for the lanes that support it. The reference acts as a composition / style anchor. The typography and illustration lanes work prompt-only.
What does a credit cost?+
Packs start at €19 for 200 credits. See /pricing for the full brochure and the per-render conversion.
