Flux 2 Dev AI Generator
Generated on PixelDojo with Flux 2 Dev. Produced by PixelDojo's generation pipeline.
Flux 2 Dev costs a flat 1 credit per image no matter the resolution, fixed at 1 megapixel output, the same price as the older base FLUX model. Our edit run on August 26, 2026 took about 21 seconds and came back with an invented prop, a wicker basket on the bicycle, that was not in the reference photo or the prompt. This page covers the fixed price, the four reference image limit, and what the model added on its own.

Flux 2 Dev
What the 1 credit Flux 2 tier adds on its own
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 we saw in the output
She arrived with a wicker basket mounted on the handlebars, a detail neither the reference photo nor the prompt specified. The street behind her leaned into saturated red and green neon rather than the cooler blue and pink mix the other tiers produced, and several pedestrian silhouettes appeared on the sidewalks. Face, glasses, hair and outfit still matched the reference.
Fixed at 1 megapixel
Dev is the only resolution priced Flux 2 tier locked to a single output size; there is no 0.5, 2 or 4 megapixel option to choose.
Four reference images, the smallest cap in the family
Half of Klein 9B's five and a fraction of Flex's ten. Fine for a single subject edit like ours, tight for a multi image composite.
go_fast instead of prompt_upsampling
Dev swaps the prompt rewriting toggle the Flex, Pro and Max variants have for a go_fast flag, on by default in our run.
Same request shape
POST to /api/v1/models/flux-2-dev/run with a prompt and input_images.
1 credit flat, fixed at 1 megapixel. About 21 seconds, and one detail we did not ask for showed up anyway.

Second fastest of the five Flux 2 tiers we timed on the identical edit prompt, August 26, 2026.
Same price as base FLUX

How It Works
How we ran the edit, so you can repeat it:
Send up to four reference images
That is Dev's cap, the smallest in the Flux 2 family. We used one.
Expect 1 megapixel output only
There is no resolution field to raise; Dev is fixed regardless of what you request.
POST to the API or run it from the tool page
/api/v1/models/flux-2-dev/run took about 21 seconds and cost 1 credit on our test.

Common Questions
Everything you need to know about Flux 2 Dev
What does Flux 2 Dev cost?
A flat 1 credit per image, fixed at 1 megapixel output. There is no resolution table because there is only one resolution.
How fast is Flux 2 Dev?
About 21 seconds in our August 26, 2026 edit run, the second fastest of five Flux 2 tiers tested that day.
How does Flux 2 Dev compare with Flux 2 Flex?
Dev costs a third less than Flex's 1 megapixel price and returned faster, 21 seconds against 25, but only takes four reference images against Flex's ten and is locked to 1 megapixel with no larger option.
How does it compare with the original FLUX model?
They cost the same 1 credit per image. Flux 2 Dev is the newer generation and takes up to four reference images for editing; check the FLUX tool page for its own current feature list before assuming full parity beyond price.
How do I call it from the API?
POST to /api/v1/models/flux-2-dev/run with your API key, a prompt, and optionally input_images for an edit, up to four URLs.
Does it add details I did not ask for?
It can. Our test run added a wicker basket to the bicycle that was not in the reference image or the prompt. The identity details we named, face, glasses, hair and outfit, still came through correctly.
