# FLUX.2 Flex

Black Forest Labs · Images · premium

FLUX.2 with more control per pass, priced a step above Pro.

## What it costs

- Resolution · 0.5 MP: 2.5 credits (≈ $0.06)
- Resolution · 1 MP: 5 credits (≈ $0.12)
- Resolution · 2 MP: 10 credits (≈ $0.24)
- Resolution · 4 MP: 20 credits (≈ $0.48)

Dollar figures are approximate, at the Starter plan's rate of $19.00 for 800 credits.

## What it takes

- **Aspect ratios**: 1:1  2:3  3:2  3:4  4:3  4:5  5:4  9:16  16:9
- **Reference images**: 7

## When to reach for it

The middle rung of the FLUX.2 family. Same nine aspect ratios, same seven references, same four-step resolution ladder. The difference is the model underneath, which is tuned for more control over the render rather than more raw capability.

Its ladder is the steepest in the family: 2.5 credits at 0.5 MP up to 20 at 4 MP. That top rung is one of the most expensive single images in the catalog, so it is worth being sure the deliverable needs four megapixels before selecting it. For most screen work 1 MP is the honest answer and costs 5.

Reach for Flex over Pro when a render keeps coming out nearly right and you need the extra handle to close the gap; reach for Pro when you are producing volume and the per-image price is what governs. If neither is landing, the problem is more likely the prompt or the reference set than the tier, and Max is unlikely to rescue it.

## How to prompt FLUX.2 Flex

FLUX.2 Flex is the tunable member of the family: the same short, atmospheric prompts as Pro, on a model meant to be dialled down to sketch resolution while you explore and back up for the final.

## Guides that cover it

- [Which image model to reach for, and when](https://meetkuro.com/guides/choosing-an-image-model.md): Twelve image models, from half a credit to twenty-one. What each one is for, where the resolution setting changes the price, and when the cheap tier is right.

## FLUX.2 Flex is one pick in the composer.

Every model in this catalog runs from the same prompt bar, priced in the same credits.
