Flux Family AI Generator
Generated on PixelDojo. Produced by PixelDojo's generation pipeline.
Three generations of Flux run on PixelDojo and they do not share a price list. Flux 2 starts at 0.1 credits an image on Klein 4B and reaches 5 credits for a 4 megapixel Flex render. The Flux 1 line sits mostly at 1 credit an image, with Kontext Max at 2 and Pro Ultra at 1.5. Flux 3 Video is billed by the second, from 5 credits a second at 720p. Below is every Flux entry in the catalog with its credit price, its size options, and what it is built to do. Every number was read from the model configuration files on August 26, 2026, not from a marketing page.
Every Flux entry, price and purpose
Flux 2 Klein 4B
0.1 credits per image, flat, whatever size you ask for. It takes up to 5 reference images, so it edits as well as it generates. This is the cheapest image in the entire catalog and the right default for drafting.
Flux 2 Klein 9B
0.5 credits per image, flat. A four step distilled build of the same Klein foundation with more headroom than the 4B, still capped at 5 reference images.
Flux 2 Dev
1 credit per image, flat. Locked to 1 megapixel output, so there is no resolution ladder to price. Takes up to 4 reference images.
Flux 2 Flex
1, 1.5, 3 and 5 credits at 0.5, 1, 2 and 4 megapixels. The default is 1 megapixel at 1.5 credits. It accepts up to 10 reference images, the largest reference budget in the Flux 2 line.
Flux 2 Pro
1, 1.5, 2 and 2 credits across the same four sizes. The curve flattens at the top, so a 4 megapixel Pro render is 2 credits where the same size on Flex is 5. Up to 8 reference images.
Flux 2 Max
2, 2, 3 and 4 credits across the four sizes. It is the highest fidelity tier of the Flux 2 line and the only one that starts at 2 credits even for a half megapixel image. Up to 8 reference images.
Flux Schnell
A single image costs 0 credits. Two images in one call cost 1 credit and three or four cost 2. Text to image only, and it takes no LoRA input. The fastest way to sanity check a prompt.
Flux Dev
1 credit per image. Text to image with adjustable steps and guidance, and it can return a batch in one call at 1 credit each. The base entry takes no LoRA.
Flux Krea Dev
1 credit per image. Photoreal generation that avoids the oversaturated look, and the one Flux 1 entry that loads a single custom LoRA with its own strength value.
Flux Dev Multi LoRA
1 credit per image. The stacking entry: pass several LoRA references with a scale for each and it combines them in one render. This is the vehicle for mixed style work.
Flux 1.1 Pro
1 credit per image, one image per call. Strong prompt adherence at the same price as Dev, with no batching and no LoRA input.
Flux 1.1 Pro Ultra
1.5 credits per image, one image per call. The top of the Flux 1 text to image line, with a raw mode for a more natural photographic look.
Flux Kontext Pro
1 credit per image. Generates and edits from the same entry, and holds the subject through an instruction like a background swap or a wardrobe change.
Flux Kontext Max
2 credits per image. The premium editing tier, and the one to pick when the edit involves readable type in the frame.
Flux Edit, the Kontext endpoint
The dedicated edit endpoint prices its three tiers at 1 credit for Dev, 1 for Pro and 2 for Max. Dev accepts a single source image only. Pro and Max take a second reference image to bias the edit. Output keeps the source aspect ratio unless you override it.
Flux 3 Video
5 credits a second at 720p and 8 at 1080p for text to video, in clips of 5 to 20 seconds. Hand it an existing clip to transform and the rate rises to 10 and 12 with the ceiling dropping to 15 seconds. Six aspect ratios, a start frame, an end frame, and audio generation on by default.
Flux Video Upscale
Billed per second of source clip. Precise mode is 4, 7 and 16 credits a second for 1080p, 2K and 4K. Creative mode, which invents finer detail, is 6, 10 and 22. Source clips up to 20 seconds.
Flux Virtual Try-On
2 credits per run. Feed it a photo of a person and a photo of a garment and it dresses the person, with an optional styling prompt.
Flux LoRA training
Two trainers. Fast Flux is 25 credits per 1000 steps and finishes in about 2 minutes. Flux 2 is 160 credits per 1000 steps and is the pick for premium character and product models.
Nineteen Flux entries priced from one source. The cheapest image is Klein 4B at 0.1 credits. The most expensive single image is a 4 megapixel Flex render at 5 credits.
Why Choose Pixel Dojo for Flux Family
Professional-quality results with cutting-edge AI technology
The cheapest Flux image is 0.1 credits
Klein 4B charges a tenth of a credit per image no matter the size. A single Flux Schnell image is free. Both are real models you can ship from, not trials.
Above 1 megapixel, Pro undercuts Flex
At 2 megapixels Flex is 3 credits and Pro is 2. At 4 megapixels Flex is 5 and Pro is still 2. The tier that sounds more expensive is cheaper as soon as you leave the default size.
Custom LoRAs live on two specific entries
Flux Krea Dev takes one LoRA with a strength value. Flux Dev Multi LoRA stacks several with a scale each. The Flux 2 variant that loaded custom LoRA weights was retired on August 25, 2026, and requests naming it are refused before any credits move.
Editing is spread across both image generations
The Kontext tiers edit from an instruction. Every Flux 2 tier accepts reference images and composes from them. So the choice is not edit versus generate, it is which price and which reference budget you need.
How It Works
How to pick a Flux tier without overpaying:
Choose the generation before the tier
Flux 1 is where custom LoRAs and multi image batches live. Flux 2 is where reference images and megapixel control live. Flux 3 Video is the only Flux entry that produces motion.
Set the output size, then compare prices
Flux 2 prices move with megapixels, and the ranking flips. At the 1 megapixel default Flex and Pro both cost 1.5 credits. At 4 megapixels Flex is 5 and Pro is 2.
Draft cheap, finish expensive
Run the prompt on Klein 4B at 0.1 credits until the composition is right, then re run the keeper on Pro or Max. Ten drafts plus one final render costs less than two Max renders.

It depends on the tier and the size. Klein 4B is 0.1 credits and Klein 9B is 0.5, both flat. Dev is 1 credit and locked to 1 megapixel. Flex is 1, 1.5, 3 and 5 credits at 0.5, 1, 2 and 4 megapixels. Pro is 1, 1.5, 2 and 2. Max is 2, 2, 3 and 4.
What is the difference between Flux 2 Flex, Pro and Max?
Reference budget and how the price scales with size. Flex takes up to 10 reference images and gets expensive fast above 1 megapixel. Pro takes 8 and holds at 2 credits for both 2 and 4 megapixels. Max takes 8, starts at 2 credits, and tops out at 4 for a 4 megapixel render.
Which Flux models can edit an existing image?
Flux Kontext Pro at 1 credit, Flux Kontext Max at 2, and Flux Kontext Dev at 1 through the dedicated edit endpoint. Every Flux 2 tier also accepts reference images and composes from them, so a Klein 4B edit costs 0.1 credits.
Can I use custom LoRAs with Flux?
Yes, on two entries. Flux Krea Dev loads one LoRA with a strength value. Flux Dev Multi LoRA stacks several with a scale for each. You can also train your own: the Fast Flux trainer is 25 credits per 1000 steps and the Flux 2 trainer is 160.
How is Flux 3 Video priced?
Per second of finished video. Text to video is 5 credits a second at 720p and 8 at 1080p, in clips of 5 to 20 seconds. Transforming an existing clip costs 10 and 12 a second and is capped at 15 seconds.
How do I call a specific Flux model from the API?
POST to /api/v1/models/{apiId}/run with your key, using the id of the exact tier you want, for example flux-2-pro, flux-2-klein-4b, flux-dev or flux-kontext-max. Same key and same request shape for every tier, so switching models means changing one string.
