FLUX.2 Pro
FLUX.2 [pro] is the production tier of Black Forest Labs' FLUX.2 family, released on 25 November 2025. BFL, the Freiburg lab founded by the researchers behind Stable Diffusion, positions it as the model you call when you want studio-grade photorealism without tuning anything: no steps, no guidance, one call. It is priced by the megapixel, which makes a 1K image about three cents.

›What we asked for
A self-portrait of FLUX.2 Pro, Black Forest Labs' image model, as a hyperreal studio photograph: a sculpted figure made of flowing black glass on a plinth, a single word 'FLUX' etched into the base, dramatic rim light, macro detail in the reflections, dark studio backdrop.

At a glance
- Price
- $0.03 for the first megapixel and $0.015 for each extra, so a 1K image is three cents and a 1920 by 1080 one about four and a half.
- Any size
- Exact width and height, priced by area.
- No tuning
- No steps or guidance; that is what [flex] is for.
- Photorealism
- BFL's pitch and the FLUX reputation; the face, food and product samples below are the test.
- Open siblings
- FLUX.2 [dev] and [klein] are downloadable if you would rather run it yourself.

Anvisha's take
FLUX.2 Pro is the photographer of this batch. The portrait is the most convincing on the site, the hard composition was exact down to three ice cubes, and it did all twelve in 8 to 16 seconds for three to four and a half cents each. It is weaker on layout: the poster is correct but oddly composed, and the infographic, while clean, is plain. The edit redrew the dripper. My rule is Pro for anything that should look like a photo and something else for anything that should look designed.
FLUX.2 Pro real output: the same 12 prompts every model gets
Every model on this site gets the same 12 prompts, so you can compare like with like. These are the pictures FLUX.2 Pro returned, one try each, nothing re-rolled or retouched. Generated on . The 12 pictures took 8 to 16 seconds each and cost $0.495 in total.
Spelling, kerning and hierarchy of three lines of set text.

Is FLUX.2 Pro free?
Black Forest Labs sells FLUX.2 by the megapixel through its own API and partners and does not run a free consumer app. Free access exists only through third parties: hosts and creative apps that bundle FLUX with sign-up credits, and the open-weight FLUX.2 [dev] and [klein] models you can run yourself.
- •BFL API: pay per megapixel, no free tier. Batches multiply the base price by the image count.
- •Open weights: FLUX.2 [dev] and [klein] can be downloaded and run locally under their licences; [klein] is Apache 2.0.
- •Third-party apps: sites like Krea, Freepik and Mistral's Le Chat bundle FLUX models with their own free allowances.

Open Moda →What we noticed running FLUX.2 Pro
- •The most photographic portrait on the site: skin, knit, hands and window light all read as a real camera. See the face and hands picture.
- •Counts and placement exact: three ice cubes, pencil across the rim, book left, apple right. See the hard composition picture.
- •Four headings, exact wording, nothing invented, but plain: grey boxes, a mismatched icon or two, no hierarchy. Correct rather than designed. See the infographic with steps picture.
- •All three lines correct and a strong risograph texture, on a composition that leaves a torn block of navy filling half the sheet. Text renders; layout is not its instinct. See the text in an image picture.
- •Edits are re-draws. Green and brass arrived on a smaller, smoother cup with no base. See the edit an existing image picture.
- •Fast and even: 8 to 16 seconds per picture, median 13.
- •Custom sizes are honoured to the pixel: 1024 by 1360, 1360 by 1024 and 2016 by 864 came back as requested. fal rounds each up to whole 1024 by 1024 megapixels, so all three billed as two, $0.045, and only the square 1K image billed as one.

What FLUX.2 Pro will not draw
Black Forest Labs licenses the FLUX.2 API models for commercial use and ships them with a safety checker that hosts leave on by default; fal exposes a safety_tolerance dial from 1 to 5, 1 strictest, and turning the checker off entirely needs account authorisation. The usual prohibitions apply: sexual content involving minors, non-consensual intimate imagery, and deceptive depictions of real people. There is no adult mode on the hosted models.
