Hard Limits DeskNotes on the MiniMax H3 Max limits that reject rather than degrade — sourced, dated, and corrected in public.

Takes per run is 1, 2, 4 or 8 — and every take is billed

MiniMax H3 Max lets you ask for 1, 2, 4 or 8 takes in a single run. The list looks like a quality setting sitting next to resolution and aspect ratio. It is not. It is a multiplier on the invoice.

Every take is billed. Asking for 8 costs eight times what asking for 1 costs. There is no bundle, no "first take free", nothing that charges for one and delivers four.

That sounds obvious written down. It is not obvious in a dropdown, and it is the single most expensive misreading available on this API.

Why the dropdown misleads

Three things make 8 look cheaper than it is:

1. It sits among settings that are free to change. Aspect ratio costs nothing. Resolution changes the rate but not the count. Takes changes the count, and the UI gives no signal that this one field behaves differently.
2. Powers of two read as tiers. 1, 2, 4, 8 has the shape of a quality ladder — draft, good, better, best — rather than a quantity.
3. One request feels like one charge. It is one API call, one job, one wait. The mental model of "a request costs a request" is correct on most endpoints and wrong here.

The arithmetic, at list price

H3 Max is $0.05 per second at 480P and $0.08 at 768P. A 15-second clip:

Takes	480P	768P
1	$0.75	$1.20
2	$1.50	$2.40
4	$3.00	$4.80
8	$6.00	$9.60

Eight takes of a 15-second clip at 768P is nearly ten dollars for one prompt. If that prompt turns out to be wrong, it is ten dollars of the wrong thing — and you asked for eight of them precisely because you were not sure.

When 8 is right, and when it is a mistake

The failure mode is using takes as a substitute for iteration. Being unsure is the case where 8 is the expensive choice, not the safe one.

• Prompt settled, you want selection — takes are exactly the tool. Same prompt, several outcomes, pick the one that cuts best. Cheaper in wall-clock time than eight sequential runs and guaranteed to share the prompt exactly.
• Prompt exploratory — one take, look at it, change the prompt. A single 5-second take at 480P is $0.25. That is your unit of learning, and it is 38 times cheaper than eight 15-second takes at 768P.

The rule that falls out: turn takes up only after you have stopped changing the prompt.

One thing that genuinely is free

Worth noting alongside, because it cuts the other way: the per-generation fee is zero credits. There is no flat charge on top of the per-second rate. So splitting work across several small runs costs you nothing in overhead — which is what makes the one-take-at-a-time iteration loop cheap enough to be the default.

Checking the numbers

Takes per run, the per-second rates, and the zero per-generation fee are all published limits with the date each last changed, on the MiniMax H3 Max specifications page. That page reads the same constants the generator enforces, so if a number there is wrong, the product is wrong too.
