The Full FLUX Family, Per Image
Schnell ✦1 · Dev ✦3 · 1.1 Pro Ultra ✦8 · Kontext editing ✦6.
FLUX, from Black Forest Labs, is the family most working creatives have settled on for stills: strong prompt adherence, clean anatomy and text that usually survives rendering. Raduga runs four members of it so you can match the model to the stage of the job rather than paying flagship prices to explore.
What FLUX is best at
- Schnell (✦1) — exploring a direction; batch up to four at once
- Dev (✦3) — the quality-per-credit workhorse for real deliverables
- 1.1 Pro Ultra (✦8) — flagship photorealism up to 4MP
- Kontext Pro (✦6) — editing an existing image with a plain-language instruction
What it costs in Raduga
From ✦1 per image (about 1.8¢ on the Spark pack). There is no subscription — you buy credits once and they never expire, and any generation that fails is refunded to your balance automatically.

How to run it
Open the studio, pick FLUX from the model list, write your prompt (or tap a preset), and generate. Everything lands in your gallery, where any result can be edited, upscaled 4×, background-removed or animated — all on the same balance.
The intended loop: draft on Schnell for a credit each, promote the survivor to Dev or Pro Ultra, then fix details with Kontext instead of re-rolling the whole image. One balance covers all four.
Other models on the same balance
- Kling 2.1 — ✦30 credits for 5s (about 54¢ on the $9 Spark pack); 10s also available.
- MiniMax Hailuo 02 — ✦35 credits for 6s (about 63¢ on the Spark pack); 10s also available.
- Seedance 1.0 Pro — ✦40 credits for 5s (about 72¢ on the Spark pack); 10s also available.
Frequently asked questions
What is the difference between FLUX Schnell and Dev?
Schnell is built for speed — a few steps, one credit, results in seconds, ideal for exploring. Dev spends more compute for better fidelity at three credits.
What does FLUX Kontext do?
Kontext edits an image you already have from a written instruction — 'make it golden hour', 'remove the passers-by' — instead of generating a new one from scratch. It costs 6 credits.
Can I generate several images at once?
Yes — Schnell and Dev support batches of up to four per run, and the button shows the multiplied cost before you click.
Is FLUX free to try?
Your 40 signup credits cover up to 40 Schnell images, with no card required.
