Flux 2 guide
Everything you can do with Flux 2
Flux 2 is the everyday tier of the Flux family: quick text to image, multi-reference editing, and a wide range of output sizes at a low per-image cost. This guide covers its resolution options, aspect ratios, and how it relates to Flux 3.
What Flux 2 is built for
Flux 2 handles both generation and editing. It takes a prompt and up to eight reference images, and offers four output sizes: 0.5K for quick drafts, 1K and 2K for most work, and 4K for final assets. Files export as JPG (the default) or PNG.
Its aspect-ratio range is among the widest in the studio. Alongside auto and the usual 1:1, 3:2, 4:3, 16:9, 9:16, and 21:9, it supports tall and wide extremes of 1:4, 4:1, 1:8, and 8:1, which suits banners, skyscraper ads, and long vertical graphics.
Four resolutions
0.5K, 1K, 2K, and 4K.
Extreme ratios
From 1:8 verticals to 8:1 banners.
Low cost
A sensible default for everyday volume.
Prompting for banners and long formats
For a wide banner, describe the composition across the frame: "left third empty for text, product on the right, soft gradient background". For tall formats, say where the subject sits and how the scene continues above and below. Naming empty space in the prompt makes it easier to add copy later.
Flux 2 compared with 2.1 and Lite
Flux 3 is the flagship, tuned for faster drafts and instruction-following edits. Flux 2 is the cheaper everyday tier with explicit resolution control. Flux 2 Flex is the lowest-cost, lowest-latency option for bulk drafts, and it has no resolution setting.
