FLUX.2 [pro]: price per image, what it does well, and who can train on your prompts
The Morse teamPublished 7 min read
As of November 2026, FLUX.2 [pro] is Black Forest Labs' default model for generating and editing images, priced from $0.03 for a one-megapixel picture on BFL's own API. It makes images up to 4 megapixels in any aspect ratio, takes up to 8 reference images through the API (10 in BFL's playground), and has no downloadable weights. BFL's API terms let it train on the prompts and images you send it, and its privacy policy offers an opt-out by email.
We read BFL's FLUX.2 model page, its launch post of November 25, 2025, the FLUX.2 docs and API reference, its pricing page and calculator, its privacy policy, terms of service, developer terms, and FLUX API service terms on November 8, 2026. Prices below come from BFL's own calculator on that date. BFL earns credit for publishing its prices per megapixel, with a calculator anyone can use without signing in.

How much does FLUX.2 [pro] cost per image?
Three cents at one megapixel, and 1.5 cents for each megapixel after that. BFL's pricing docs list FLUX.2 [pro] "from $0.03" for text to image and "from $0.045" for editing, with 1 credit equal to $0.01 and the "Same price for API and Playground" (BFL). Editing costs more because the calculator counts the megapixels of your input images as well as the output. A batch of four is four times one image.
We set BFL's pricing calculator to each size with no input images on November 8, 2026, and set the same sizes beside the rest of the family:
| Output size | FLUX.2 [pro] | FLUX.2 [flex] | FLUX.2 [max] | FLUX.2 [klein] 4B | FLUX 3 Image |
|---|---|---|---|---|---|
| 1 MP (1024 × 1024) | $0.030 | $0.050 | $0.070 | $0.014 | $0.048 |
| 2 MP (1440 × 1440) | $0.045 | $0.100 | $0.100 | $0.015 | $0.07 |
| 4 MP (2048 × 2048) | $0.075 | $0.200 | $0.160 | $0.017 | $0.10 |
FLUX 3 Image is priced per resolution tier rather than per megapixel, so its column comes from BFL's published tiers. At 4 megapixels, [flex] costs more than twice what [pro] does, and [pro] costs three quarters of FLUX 3 Image, BFL's newer model.
What is FLUX.2 [pro] good at?
Production work that has to stay consistent. BFL's docs call [pro] "the recommended default model for most generation and editing" and "production-grade" (BFL). What BFL claims for the FLUX.2 family:
- The same face or product across many images. Up to 8 references through the API, for ad variants and product shots in new settings.
- Exact brand colors. Hex codes in the prompt, such as
#02eb3c, are matched rather than approximated, by BFL's account. - Structured prompts. A JSON prompt with fields such as subject, lighting, and camera angle, for repeatable workflows.
- Text in images. Typography, infographics, and UI mockups, though BFL's overview calls [flex] the one "specialized for typography."
The benchmark charts in the launch post are BFL's own. We didn't run our own tests.
FLUX.2 [pro] vs [max], [flex], [dev], and [klein]
BFL's overview sorts the family by job (BFL):
- [max]: the highest quality, and the only one with grounding search, which looks things up on the web before drawing, such as yesterday's match score.
- [pro]: "Top performance at affordable price," for production at scale.
- [flex]: adjustable steps and guidance, best for text and small details.
- [dev]: a 32-billion-parameter open-weight model, free for non-commercial use, with no hosted API.
- [klein]: sub-second models with open weights. The 4B runs on consumer cards with about 13 GB of VRAM under Apache 2.0, and the 9B is under BFL's non-commercial license.
FLUX.2 is no longer BFL's newest family. BFL's blog introduced FLUX 3 on July 23, 2026, and FLUX 3 Image Klein on October 15, 2026 (BFL). Its docs say "FLUX.2 remains fully supported for production image generation and editing."
Can you run FLUX.2 [pro] locally?
No. BFL publishes weights for [dev] and [klein] only, so [pro] runs on BFL's servers or through partners it licenses. The nearest local option is FLUX.2 [dev], and using it commercially needs one of BFL's paid self-hosting licenses (BFL). If you need a local model you can use commercially without a license deal, [klein] 4B is Apache 2.0. Our page on Z-Image Turbo covers another open model that fits on a 16 GB card.
Does Black Forest Labs train on your FLUX.2 prompts?
Yes, by default, on its API and in its playground. The FLUX API service terms give BFL a "perpetual, irrevocable, worldwide, non-exclusive, and fully sublicensable" license to your inputs and outputs and say this "means the Company may use Inputs and Outputs to train and improve its artificial intelligence models" (BFL). The EU version of those terms has the same clause (BFL). The privacy policy, which covers the playground and the APIs, says BFL may use your prompts, uploaded images, and outputs "to train and improve our AI models after implementing appropriate technical safeguards like data minimisation and deidentification techniques" (BFL).
The opt-out is an email, and BFL's documents name two addresses for it. The privacy policy says to write to privacy@blackforestlabs.ai with the subject "Training Opt Out" and your account details. The terms of service say legal@blackforestlabs.ai, and add that opting out works only going forward. It doesn't cover content "already used to train a model," content kept "for safety, security, or legal compliance purposes," or anything you sent as feedback (BFL). The privacy policy doesn't apply to content BFL processes under an enterprise contract, which has its own terms.
Who else sees what you make with FLUX.2 [pro]?
BFL, its service providers, and anyone you share with. The privacy policy says "No advertising cookies are used," and BFL sets its PostHog or Clay analytics cookie only if you accept the banner. BFL's terms say content "may be shared or visible to others" through features such as Prompt Party, and its terms require users to be 18 or over. BFL keeps your information "for as long as is reasonably necessary" without a fixed period. If you live in the EEA, Switzerland, or the UK, your data controller is BFL GmbH in Freiburg; elsewhere it's Black Forest Labs Inc in San Francisco. Developers who want requests kept in Europe can call api.eu.bfl.ai, which BFL's integration guide describes as "limited to EU regions" (BFL).
How to use FLUX.2 [pro] without a BFL account
On BFL's API or playground, your prompts and pictures sit with BFL under a license that includes training, tied to an account in your name, and an opt-out email covers only what you send afterwards. Morse's Studio lists FLUX.2 [pro] among its image models, so you can use it from a Morse account instead, with no BFL account or API key of your own. The pictures come back to your device.
- No BFL account in your name. Morse doesn't train AI on your content, sell your data, or show ads, and there's no BFL account of yours to send a "Training Opt Out" email from.
- Results that stay with you. A FLUX.2 [pro] image lands in Studio, which stores it in your browser, encrypted, instead of behind a 10-minute download link. Clearing the browser deletes it, so save the ones you'll use. Our Z-Image Turbo page walks through Studio's storage and its Free plan.
- Plan details in the app. Open Studio's model menu to see where FLUX.2 [pro] sits on your plan.
FLUX.2 [pro] reads long, structured prompts well, so it pays to draft them first. Do that in a Morse chat, in the mode that fits:
- Private, to build a JSON prompt with an open model. DeepSeek, Kimi, or GLM writes it, and Morse has zero data retention agreements with its inference, search, and other providers.
- E2EE, for a campaign brief no one should read. Your browser checks the enclave's proof before anything leaves your device, and the guarantee rests on the enclave hardware and attestation working as designed. E2EE comes with Pro, and image generation doesn't run in it, so copy the finished prompt into Studio.
- Anonymous, to have GPT, Claude, or Gemini check the hex codes and layout. The provider gets the text without knowing it's you, and may keep it for a limited time to check for abuse, under its own policy.
Which way to use FLUX.2 [pro]
- You're building an app on it: use BFL's API, budget $0.03 to $0.075 an image, download results within 10 minutes, and email the training opt-out on day one.
- You need it on your own hardware: you can't; license FLUX.2 [dev] or run [klein] 4B instead.
- You want to make images without a BFL account, kept on your device: use Studio on Morse.

Common questions
Is FLUX.2 [pro] free to use?
No. Black Forest Labs charges per image on its API and in its playground at the same rates, with 1 credit worth $0.01. The free option in the family is FLUX.2 [dev], whose open weights you can run yourself for non-commercial use.
Does FLUX.2 [pro] rewrite my prompt?
By default, yes. BFL's API reference says FLUX.2 [pro] and [max] apply prompt upsampling unless you set disable_pup to true, which generates from your prompt exactly as written.
How long do FLUX.2 [pro] image links last?
Ten minutes. BFL's integration guide says generated images expire after 10 minutes, and that the delivery URLs aren't meant to be served to end users directly, so download each result as soon as it's ready.
Is FLUX.2 [pro] better than Midjourney?
Neither company publishes a head-to-head we could check. BFL's own claims for FLUX.2 center on multi-reference consistency, text rendering, and exact hex colors, so try both on the work you actually do.
