Which one is for you
Pick FLUX by Black Forest Labs if
- Fits if you make the odd image and would rather pay per picture than monthly
- Works for developers building image or video generation into their own product
Look elsewhere if
- 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 and $0.17 a second for HD video
- Pricey if you make hundreds of FLUX 3 images a month, as every one is charged
- Watch out: FLUX.2 [klein] 9B, FLUX.2 [dev] and FLUX.1 [dev] weights are non-commercial, and license prices aren't published
- Skip it if you want a phone app, integrations or a student discount, as the listing shows none
Pick Seedream if
- Fits if you generate images in volume and want to pay per image
- Works for developers who want an image model behind their own app
Look elsewhere if
- Skip it if you want a finished app with a gallery and editor, as this is a model
- Tight if you buy packs and use them slowly: they expire after 30 days and unused images are lost
- Pricey if you read the discounted prices as the real ones, since $6.99, $24.99 and $49.99 are for a first purchase only
- Watch out: versions 4.0, 5.0 Lite and 5.5 all appear across ByteDance pages, and the packs are stated for 5.5
How we grade them
| 2.0GPAFLUX by Black Forest LabsFair | 1.6GPASeedreamWeak | |
|---|---|---|
| Value for money | CNo 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. | C$13.99 for 700 images, about 2 cents each, and $35.99 for 1,800. Those are pay-as-you-go packs the category's monthly figures can't be set against, so it sits in the middle. The cheaper first-purchase prices apply once. |
| Free plan and trial | CThe 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. | FNo free plan or trial on the listing. A first pack is discounted to $6.99, which is still a purchase. |
| Features | CFLUX 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. | CText-to-image and prompt-based editing in one model, transparent backgrounds and multi-turn edits. It's a model, not a full app, so there is no gallery, library or editor around it. |
| Ease of use | CNo 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. | CNo store rating on record. It's sold as API access and image packs, which suits people who are comfortable calling a model rather than opening an app. |
| Platforms and integrations | CA web playground and an API, plus open weights to run on your own machine. No phone app and no integrations in the listing. | CWeb only, with an API through BytePlus. No phone or desktop apps and no integrations are named. |
| Best for | pay-per-image FLUX models and open weights | an image model bought by the pack or through an API |

More comparisons
How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
