Flux.2 Max

What is Flux.2 Max?#

Flux.2 Max is the quality-focused image model in Black Forest Labs' Flux.2 family. It is meant for selected final results rather than setting sweeps. The API accepts the shared Flux.2 prompt, output-size, aspect-ratio, and reference-image inputs, while leaving manual steps and guidance to the Flex model.

Output can be set to 0.6, 1, 2, or 4 megapixels. Seven aspect ratios cover ultrawide, landscape, square, and portrait work. A request can also include up to ten reference image URLs, allowing a final render to follow product images, approved compositions, or a visual brief.

Key features of Flux.2 Max#

Quality-focused Flux.2 model

Max is intended for the selected image at the end of a workflow: key art, campaign stills, covers, and hero images that need the family’s highest output setting.

Four output sizes

Choose 0.6, 1, 2, or 4 megapixels. Smaller sizes suit checks; larger sizes give a selected result more room for display and crop needs.

Seven aspect ratios

The available shapes run from 21:9 landscape through 1:1 square to 9:21 portrait, covering common campaign and product layouts.

Up to ten references

Attach reference image URLs to guide the subject, layout, or visual direction while keeping generation on the Max model.

Shared family request shape

Pro, Flex, and Max use the same core inputs. A workflow can test on another family member and change the model identifier for the final result.

Best for#

Variants#

Flux.2 Max shares its core image inputs with Pro and Flex. The models differ in where they fit in the work.

Max#

Use Max for the selected final image. It keeps the core output-size, aspect-ratio, and reference-image options without exposing manual steps and guidance.

Pro#

Use Pro for routine production batches and everyday image work. It is the balanced model in the family.

Flex#

Use Flex when you need to test steps, guidance, seed, or prompt upsampling before settling on a request.

Use cases#

For campaign work, test the prompt and references first, then send the approved setup to Max for the selected key art. A product team can attach approved product images and produce a 21:9 site banner, a 1:1 catalog tile, and a 9:16 social asset from the same visual direction. For editorial or presentation work, choose the aspect ratio before generation so the main subject has room for copy and crop changes. Smaller output settings are useful for checks, while 2 or 4 megapixels suit the final image when more display or crop room is needed.
