FLUX.2: realistic scenes and different levels of control
| Model | Tasks to try | Settings and limits here |
|---|---|---|
| FLUX.2 Klein 4B | Composition drafts, subject shape, and reference edits. | Ratio, seed, PNG/JPEG. Reference limits differ from the other FLUX.2 models. |
| FLUX.2 Pro | Products, people, clothing, and material studies with references. | Ratio, seed, PNG/JPEG; no Flex-specific steps or guidance. |
| FLUX.2 Flex | Compare the generation process and instruction constraint with fixed input. | Ratio, seed, PNG/JPEG, plus steps and guidance. |
| FLUX.2 Max | Another choice for comparing subject, material, and reference relationships. | Main controls currently match Pro; no web search. |
Usage, cautions and actual examples
No separate negative prompt, web search, manual thinking level, output count, resolution tier, or exact-dimension input is currently offered. Ratio shapes the image but does not promise fixed pixels. Choose a model with a size control when exact dimensions are required.
With Flex, fix input and seed, compare steps first, then guidance. More is not always better. A blank seed leaves random handling to this request; even an explicit seed does not reproduce images across models or changed settings.

FLUX.2: Black Forest Labs moderation
Black Forest Labs may reject inputs before processing or block results after generation. BANANAI shows the shared provider-moderation notice; a specific reason may not be available. The four FLUX.2 models share this explanation unless a model-specific difference has been confirmed.
Usage restrictions follow the provider's official policy. A prohibition on infringing third-party rights is not a blanket ban on every brand name or logo. One refusal does not prove that a word or subject is always prohibited.
