The deciding question is whether your image has words in it. GPT Image 2 (medium) keeps small type readable and costs 14 credits. FLUX 2 [max] gives the more photoreal default at 16 credits.
Photos without text versus anything with lettering
FLUX 2 [max] is built for everyday photoreal generation and iteration. Think portraits, product scenes, food and interiors that should look shot on a camera. Its listed weak point is text, where GPT Image 2 is stronger. A shop sign or a label may come out garbled.
GPT Image 2 (medium) is the pick for posters, menus and interfaces. It suits any image where type must stay readable at small sizes. It also follows unusual instructions literally. Odd compositions such as "a cat reading a newspaper whose headline says MONDAY AGAIN" land as described. The trade-off is listed plainly: it is not the most photoreal option.
Frame shapes differ more than you might expect
FLUX 2 [max] offers 1:1, 4:5, 16:9 and 9:16. That covers feed posts, widescreen banners and vertical stories. GPT Image 2 (medium) offers 1:1, 3:2 and 2:3. Those fit print-style posters and classic photo frames, but not a full 9:16 story. If the destination is a vertical video cover, FLUX is the one that fits without cropping.
Cost per image and per batch
One image is 16 credits on FLUX 2 [max], about $0.17 at the best pack. On GPT Image 2 it is 14 credits, about $0.15. Ten separate runs come to 160 against 140 credits, or $1.70 against $1.49. Among 41 image models, they rank 36th and 32nd from the cheapest, so neither is a budget option.
Tools: shared ground and exclusive ones
Both run in the AI Image Generator, AI Image Editor and AI Photo Editor. They also share Image to Image, Expand Image and AI Pet Portrait, among other tools. FLUX 2 [max] alone powers the AI Tattoo Generator, Line Art Generator and AI Wallpaper Generator. The AI Avatar Generator and AI Character Generator also run on FLUX alone. GPT Image 2 alone runs text-heavy and commercial tools. Examples are YouTube Thumbnail Generator, AI Ad Generator, AI Meme Generator, Remove Text and Virtual Staging AI.
A single prompt that shows the difference
In the AI Image Generator, pick the Poster with text preset. Run this prompt on both: "A rainy street café at dusk, warm light inside. A chalkboard in the window reads TODAY: LEMON TART 4 EUR." Check two things: is the chalkboard legible, and does the street look like a photo? Expect FLUX to win the street and GPT Image 2 to win the board.
If you need both, generate the scene on FLUX 2 [max]. Then open the AI Image Editor on GPT Image 2. Its Fix the text preset corrects the lettering.
