Verdict

The verdict

Choose Flux 3 when the render has to contain legible words, or when the prompt is long enough that a model quietly dropping a clause would matter. Flux.2 remains a capable generator and the gap is narrower here than in any other comparison on this site, but Flux 3 is the stricter reader of the two — and on this site it is free, anonymous and needs no account.

At a glance

Text rendering: Flux 3 Reliable spelling in signage and logo text; Flux.2 Usable, but degrades on longer strings
Prompt adherence: Flux 3 Follows long, multi-clause prompts as written; Flux.2 Strong, with occasional dropped clauses
Speed: Flux 3 About 2 to 5 seconds per render; Flux.2 Comparable, hardware dependent

Which to pick

When to pick which

When to choose Flux 3:

Any render where text is part of the design — a poster, a shopfront, a mockup with a label — is where Flux 3 separates from Flux.2 most clearly. The same is true of dense prompts: if you have written four clauses and you need all four, Flux 3 is the model that keeps them. It also matters that Flux 3 is reachable here with no sign-up, so testing the difference costs you nothing but the time to type a prompt.

When Flux.2 is still the right call:

Flux.2 is not a weak model and plenty of workflows are already built around it. If you have an existing pipeline, a set of tuned prompts that behave predictably, or a host you are happy with, there is no urgency to move. Flux.2 also remains a reasonable image-to-image partner, which is why the Flux 3 Edit workflow on this site is built on that lineage rather than against it.

The underlying difference

The two models come from the same family, so the difference is not a change of character but a change of discipline. Flux 3 is tuned to treat the prompt as a specification rather than a suggestion, and that shows up in two places: words render as words, and long prompts survive intact. Everything else — palette, style range, speed — is close enough that you would struggle to pick a winner blind.

On text rendering and long-prompt adherence, yes, consistently. On general image quality the two are close enough that the answer depends on your prompt and your taste. The honest test is to run the same prompt through both.
