Flux 2 Klein 9B AI Generator
Generated on PixelDojo with Flux 2 Klein 9B. Produced by PixelDojo's generation pipeline.
Flux 2 Klein 9B costs a flat 0.5 credit per image, the same price at every resolution, and our edit run on August 26, 2026 finished in about 15 seconds, the fastest of any Flux 2 tier we tested that day. It is a 4-step distilled foundation model, and the speed shows: it returned before Flux 2 Flex, Pro, Max or Dev on the identical edit prompt. This page covers the price, what the output looked like, and where the distillation shows.

Flux 2 Klein 9B
What the fastest Flux 2 tier trades away
What we asked it to do
The same instruction as every other Flux 2 tier: place the reference woman on a bicycle crossing a rainy city crosswalk at dusk, keeping her face, glasses, hair and outfit identical.
What came back
A wider, busier street than Flex produced: more storefronts, two pedestrians on the sidewalk, three cars instead of two, and a taller cluster of vertical neon signs. Her face, glasses, red curly hair, denim jacket and yellow shirt all matched the reference. The bicycle frame reads a slightly different color than in the other tiers' results, a small consistency gap the distilled model does not fully close.
Fixed pricing, no megapixel math
Klein 9B and Klein 4B are the only two Flux 2 variants that do not price by resolution. Klein 9B is five times the price of Klein 4B for a larger nine billion parameter model.
disable_safety_checker instead of a five level dial
Klein 9B skips the safety_tolerance slider the Flex, Pro and Max variants expose, using a single on or off flag instead.
0.5 credit flat, about 15 seconds. The quickest Flux 2 result we timed that day, on the same edit prompt every other tier ran.
Why Choose Pixel Dojo for Flux 2 Klein 9B
Professional-quality results with cutting-edge AI technology
0.5 credit, fixed
No resolution table to check. Text to image and image edit are both a flat 0.5 credit, up to five reference images per request.
About 15 seconds, measured
The fastest of the five Flux 2 tier runs we timed on August 26, 2026, on the identical scene-placement edit prompt.
Five reference images
Half of Flex's ten but ahead of Dev's four, at a third of Flex's 1 megapixel price.
How It Works
Getting the fastest Flux 2 result:
Pick Klein 9B when speed matters more than the finest detail
It returned in about 15 seconds against 21 to 41 seconds for the other Flux 2 tiers on the identical prompt.
Keep reference images to five or fewer
That is the cap. Klein 9B and Klein 4B are the two Flux 2 variants built around speed over reference count.

Common Questions
Everything you need to know about Flux 2 Klein 9B
What does Flux 2 Klein 9B cost?
A flat 0.5 credit per image at any resolution, for both text to image and image edit. Reference images do not add to the price.
How fast is it?
About 15 seconds in our August 26, 2026 run, the quickest of five Flux 2 tier tests on the same prompt that day.
How does it differ from Flux 2 Klein 4B?
Klein 9B is a larger, nine billion parameter distilled model at five times Klein 4B's 0.1 credit price. Both accept up to five reference images and skip the resolution pricing table the larger Flux 2 variants use.
Is Klein 9B as detailed as Flux 2 Pro or Max?
Not on our test. The background in our Klein 9B result was busier but the bicycle frame color drifted slightly from the reference, a small consistency slip Pro and Max did not make on the identical prompt.
How do I call it from the API?
POST to /api/v1/models/flux-2-klein-9b/run with your API key and a prompt. Add input_images for edit mode, up to five URLs.
Can it generate from a blank prompt, not just edit?
Yes. Leave input_images empty and it generates from text alone at the same 0.5 credit rate.
