Where this family fits.
Prompt-led image generation with a named FLUX.2 policy
Tasks that need a current 1K or 2K catalog choice on Pro or Flex
Quick 1MP drafts on a klein variant with a few reference images
What not to assume.
The current catalog does not maintain a quality comparison between any FLUX.2 variants
klein 4B and 9B list only a 1MP entry and at most four reference images
The named tool begins with FLUX.2 Pro rather than exposing a public family selector
Generated detail, text, and identity still require inspection
Two resolution tiers
FLUX.2 Pro and Flex both list 1K and 2K and accept up to eight reference images. FLUX.2 klein 4B and klein 9B run at a fixed 1MP entry, accept up to four references, and add a 21:9 ratio. The page records those differences without turning the variant names into a performance comparison.
The tool starts with Pro
The compatible FLUX generator currently names FLUX.2 Pro in its task contract. Flex and both klein variants remain available in the model catalog, and a Vizify request can name one of them explicitly.
Evidence boundary
Availability and parameters were checked against the Vizify generation catalog on 2026-09-26. Search demand and external quality evaluation require independent evidence.
