Flux 2 Klein 9B Image edit pricing
wavespeed-ai/flux-2-klein-9b/edit
The 9B-parameter Klein tier of Flux 2. One flat price per image, sized by a width*height string up to 2048 pixels a side, with no quality control.
What it costs
Per image, and what that comes to at volume. Every figure is computed through the same function the app estimates a real run with.
| Tier | per image | 1 image | 10 images | 100 images | 1,000 images |
|---|---|---|---|---|---|
| Flat rate | $0.016 | $0.016 | $0.16 | $1.60 | $16.00 |

Things that catch people out
- Accepts at most 3 input images, one short of a full persona selection of 4, which Start refuses rather than trims.
- The endpoint marks its size parameter hidden, but takes it: Personifex sends the ratio you pick at a 2048 pixel long edge.

Others in this lane
Image to image. You supply one or more reference images and a prompt, and the model returns a new image of the same subject. This is the lane every persona workflow runs on, because the reference is what holds the face steady.
