Best for pay-per-image FLUX models and open weights

Black Forest Labs makes the FLUX models, and you use them in a browser playground or through an API, paying per image with no subscription. A FLUX 3 image is under 5 cents, and some weights are free to run on your own machine. It's an engine rather than an app, though: no phone app, and little around the playground.

Who FLUX by Black Forest Labs is for

  • Great if you make the odd image and would rather pay per picture than monthly
  • Handy when you're building image or video generation into your own product
  • A treat if you have a strong graphics card and want to run and fine-tune a model yourself

Who FLUX by Black Forest Labs is not for

  • Skip it if you want an app with styles, projects and a gallery, not a playground
  • Not for you if you need a known monthly bill, since you pay per image
  • Pricey if you make hundreds of FLUX 3 images a month, as every one is charged

Why FLUX by Black Forest Labs gets a 2.0

Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.

  • CValue for moneyNo subscription, so no monthly plan to set against this category. You prepay credits at $0.01 each: a FLUX 3 image costs $0.048 and a Klein one $0.009, so $10 makes about 200 FLUX 3 images. Light use beats any plan here, heavy use won't.
  • CFree plan and trialThe FLUX.2 [klein] 4B weights are free under Apache 2.0, commercial use included, but only if you can run them on your own hardware. The hosted playground and API have no free credits on record.
  • CFeaturesFLUX 3 makes images with accurate text and clips up to 20 seconds with sound, and FLUX Tools erase, outpaint and deblur. For a person, though, the listing shows a playground over an API, with no styles, projects or gallery around it.
  • CEase of useNo app rating on record. The playground needs no code, but you're buying credits, picking models and resolutions and paying per image, which is a developer's way of working.
  • CPlatforms and integrationsA web playground and an API, plus open weights to run on your own machine. No phone app and no integrations in the listing.

Keep FLUX by Black Forest Labs, or make your own?

Keep it

To replace FLUX by Black Forest Labs you would be making an image model, which you can rent by the picture but not make. That is not a weekend's work, with an AI app builder or without one.

That makes this kind of software worth paying for, not this one in particular: 16 of the 21 other AI image and video generators grade higher.

What you could not

  • An image model, which you can rent by the picture but not make.
  • A video model, which you can rent by the second but not make.
  • An API that other software can build on.
  • AI features, unless you pay a model provider for each request yourself.

What this rests on. FLUX by Black Forest Labs’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
