Paid tiers in this category advertise quality. Quality is not what separates them, because the free tier draws from the same distribution.
What actually separates them
Repeatability. One good image out of forty attempts is luck. Forty usable out of forty is a product. That distinction only appears if you generate more than you need and count, which is tedious and therefore rarely done in reviews.
Consistency across people. The moment it is a workforce, the requirement stops being quality and becomes uniformity — the same crop, background and colour temperature across faces with different hair and colouring. A different technical problem, and a harder one.
Usage rights that hold. Irrelevant for a personal profile. Not irrelevant for advertising.
The professional-grade version is built around those, and how the generators work covers the mechanism underneath without the marketing layer.
The case with actual specifications
Residency and medical application photographs come with stated requirements — often a background colour and a crop — which turns a taste decision into a compliance one.
Check the rules before producing anything. A rejected photograph costs an application cycle, and the requirements are usually published somewhere unhelpful.
What to do with the output
More than one placement. Using one portrait across an online presence is realistic about the limits, and the underrated benefit is recognition: the same face in five places is worth more than five better faces in five places, and it costs nothing.
Why the prices moved
The cost of running these models fell sharply, and the category went from expensive to nearly free at entry level. The market numbers show the movement.
The consequence for a buyer is concrete: any comparison written before roughly 2025 describes prices that no longer exist, so check the date before the ranking.
The thing that decides the result regardless of tier
Source photographs from different days, in different clothes, in different light. Fifteen images from one afternoon in one shirt teach the system that the shirt is part of your face.
No paid tier rescues a bad input set, and no free tier is held back by a good one.
