The re-roll tax: why a usable AI image costs more than one render, and how to pay less

Every pricing page, including ours, tells you what one render costs. None of them can tell you what one picture costs, because that number depends on you: on the prompt, the subject, and how many times you press Generate before you get something you would actually use. The gap between the two prices is what we call the re-roll tax. It is real, it is larger than most people assume, and it is mostly within your control. This post is about measuring it and shrinking it.

The arithmetic nobody puts on the pricing page

Call the rate you are charged per render the sticker price. Call the number of renders you make for each picture you keep your re-roll rate. The real price of a usable image is the sticker price multiplied by the re-roll rate. If you keep one picture in three, a render on Still at €0.40 is really costing you three times that per picture. If you keep one in one and a half, the tax is half the sticker price. Nothing about the model changed between those two cases; only the rate did.

The rate is not a fixed property of a tool. On clean, single-subject work (a bottle, a landscape, an abstract texture) it is often close to one. On faces, hands, groups of people, legible text and precise counts it climbs quickly, and that is true of every generator on the market, not a quirk of one. The cost estimation method uses a flat one and a half as a planning number; the point of this post is that your own number can be better than that.

Measure yours before you try to lower it

You cannot improve a number you have not seen. For one week, do this: every time you finish a session in the studio, count the renders in your feed and count the ones you downloaded or reused. Divide the first by the second. That is your re-roll rate for that kind of work. Most people find they have two very different rates, a low one for the subjects they have learned to prompt and a high one for everything else, and the high one is where the money goes.

Six habits that cut the tax

1. Draft on the cheap model, finish on the good one

Most re-rolls are composition re-rolls: the angle is wrong, the framing is wrong, the palette is wrong. None of that needs the top model. Explore on Still Lite, from €0.30 a render, until the picture is right in the small, then re-render the winning prompt on Still. You pay the high sticker price once, for the picture you keep, rather than for every miss along the way.

2. Change one thing per re-roll

A re-roll that changes the subject, the lighting and the lens at once teaches you nothing, because you cannot tell which change helped. Hold everything constant and move one word. The second render is then a measurement, not another lottery ticket, and three measured renders usually land where ten random ones would not.

3. Stop re-rolling for text and exact counts

Legible headlines, logos and "exactly seven" of anything are the highest-tax subjects there are. Leave clean space for the text and set it in your own editor; describe a crowd as "a few" or "a small group" rather than a number. The hands and text guide has the longer list of what to prompt around instead of re-rolling through.

4. Reuse what landed

Once one picture in a set is right, every later picture should start from it. Attach it as a reference and the model inherits the palette, the lighting and the style, so the later renders only have to get the new subject right. On a set of ten, the first picture may take eight renders and the remaining nine two each; the average is a different number from the first.

5. Write the prompt down before you type it

A prompt improvised in the box tends to miss the thing you wanted most, and you notice only when the render arrives. Thirty seconds spent on a sentence that names the subject, the setting, the light and the frame in that order, as the prompt guide lays out, removes the first two or three re-rolls that were really just you finding out what you meant.

6. Know when a miss is not your fault

A render that fails with an error costs nothing: the amount returns to your balance automatically, so it is not part of your rate. But a render that comes back as a picture, just not the one you wanted, is charged, and counting those honestly is the whole exercise. Keep the two cases separate in your head, otherwise the tax looks either better or worse than it is.

A worked fraction

1. 01An untrained session: eight renders on Still to keep two pictures. Rate four. Real price per picture: four times €0.40.
2. 02The same brief with the habits above: five drafts on Still Lite at €0.30, then three finals on Still to keep two. Real price per picture: two and a half drafts plus one and a half finals.
3. 03Work it out at the current rates and the second line is well under half the first, for the same two pictures. The sticker price did not move. The rate did.

What the top quality setting does to the fraction

The top quality setting on Still, at €0.60, is the most expensive render in the studio, and the mistake is to explore at that price. It belongs on the last render only: the prompt is already proven at the standard setting, so the re-roll rate at the high setting should be close to one. If you find yourself re-rolling at the top setting, go back a step; the problem is the prompt, and it is cheaper to fix there.

What this cannot fix

No habit brings the rate to exactly one on open-ended creative briefs, where the client will know the right picture when they see it and not before; budget for that. Some subjects stay expensive whatever you do: large groups, mirrors, long text. And lowering the rate is not the same as lowering the sticker price, which is set per model and shown in the composer before you confirm each render. What you control is the multiplier, and the multiplier is usually the bigger number.
