FLUX.2 Max vs Pro vs Klein 4B

Klein halves the references. Max and Pro are identical on every setting the picker shows, which leaves the descriptions doing all the work.

What to lock before you start generating

Six decisions. Three of them can't be changed later at all, and one of those surprises almost everyone.

Four stacked bars of descending length, with one shorter bar carrying an extra marker

Seedance 2.5 vs 2.0 vs 2 Fast vs 2 Mini

Four models, and the flagship isn't the most capable on every axis. One of the cheaper two does 4K and it doesn't.

Two panels side by side, one showing an image icon and the other showing it crossed out
Models
Wan 2.7 vs Wan 2.6

These aren't two versions of the same model. One composes from references; the other restyles footage and won't take an image at all.

How to fix a shot without regenerating it from scratch

Edit mode conditions on footage you already have, so framing, light and identity carry forward. What it can't do is target an area.

Who owns the face in your AI video? The actor-rights decision, explained

Every rule that matters turns on one question: is this face readily identifiable as a real person's?

Can AI video be copyright protected?

Owning your output and holding copyright in it are two different things, and your platform can only give you the first.
