MiniMax H3 vs Veo 3.1 is not a quality argument, it is a billing argument. MiniMax H3 charges by the second at a fixed 2K; Veo 3.1 on its Lite tier charges by the clip. On one Kavel credit balance a five-second MiniMax H3 run costs about 158 credits, while an eight-second Veo 3.1 Lite run costs about 45 — and the gap widens with every second you add.
Pick Veo 3.1 when length is uncertain or you need sound in the render — Veo 3.1 Lite is billed per video, so a 4-second draft and an 8-second final cost the same.
Pick MiniMax H3 when you want one fixed 2K output and clips longer than Veo 3.1 will run — H3 goes to 10 seconds here and never asks you to choose a resolution.
The two overlap on almost nothing: different resolution model, different billing shape, different maximum length.

Veo 3.1 bills per clip, MiniMax H3 bills per second
Most comparisons of MiniMax H3 vs Veo 3.1 tabulate resolution and stop there. The number that actually moves your bill is the billing shape, and these two models do not share one.
Veo 3.1 on the Lite tier is priced per video. Length never enters the estimate. MiniMax H3 is priced per second, and because its resolution is fixed there is no tier to trade against — duration is the entire cost equation.
| Clip length | Veo 3.1 (Lite, 720p) | MiniMax H3 (fixed 2K) |
|---|---|---|
| 4s | ≈ 45 credits | not offered (5s floor) |
| 5s | ≈ 45 credits | ≈ 158 credits |
| 6s | ≈ 45 credits | ≈ 190 credits |
| 8s | ≈ 45 credits | ≈ 253 credits |
| 10s | not offered (8s ceiling) | ≈ 316 credits |
These are Kavel's own credit rates, read from the live pricing page rather than converted from a provider's dollar list. Veo 3.1 at 1080p is about 53 credits, still per video.
Iterating is nearly free on Veo 3.1 and expensive on H3
Six drafts at eight seconds each cost about 270 credits on Veo 3.1 Lite and about 1,518 on MiniMax H3. If your workflow is re-roll-until-right — and for most people it is — the billing shape decides more than either model's output does.
There is no crossover point
Per-clip pricing beats per-second pricing at every length both models offer. Veo 3.1 does not become the expensive one at eight seconds, or at four. MiniMax H3 earns its cost on what it delivers — a fixed 2K frame and a longer ceiling — not on being cheaper at some duration you have not tested yet.
What Veo 3.1 and MiniMax H3 actually give you
Veo 3.1: sound arrives in the same render
Veo 3.1 is Google DeepMind's video model, and the thing Veo does that MiniMax H3 does not advertise is return audio in the output. A short scene that would otherwise need a separate audio pass and an editing suite comes back closer to finished.
Veo 3.1 also accepts first and last frames plus one to three image references, so you can pin the start, the end, or the look instead of re-rolling a prompt and hoping. That control surface is the real argument for Veo 3.1 in a MiniMax H3 vs Veo 3.1 decision: frame guidance turns a lottery into a revision. Output runs 720p, 1080p or 4K, at 4, 6 or 8 seconds, in 16:9 or 9:16.
MiniMax H3: one output, one decision
MiniMax H3 — also sold under the Hailuo name, and the successor to that line rather than a variant of it — takes a prompt or a still and returns a moving shot at 2K. Most models sell 720p, 1080p and 4K at different per-second rates the way Veo 3.1 does; H3's API accepts one value and returns 2K every time.
That removes the most common way of overspending by accident, which is picking a tier you did not need, and replaces the whole decision with a single question: how long should the clip be. Text-to-video and image-to-video both run on the same model, and starting from a still is the more predictable of the two, because the opening frame is no longer something the model has to invent.
The whole MiniMax H3 cost equation is one number: seconds. The whole Veo 3.1 Lite cost equation is zero numbers — the clip costs what it costs.
Where the length ceiling settles it
MiniMax H3 offers 5, 6, 8 and 10 seconds on Kavel, against a model ceiling of fifteen. Veo 3.1 stops at eight. If your shot has to run past eight seconds in a single generation, the MiniMax H3 vs Veo 3.1 comparison ends right there — Veo 3.1 cannot do it and H3 can.
What neither the Veo 3.1 nor the MiniMax H3 spec sheet tells you
Two things about MiniMax H3 are genuinely unconfirmed, and we would rather say so than fill the gap: frame rate and generated audio are not confirmed on the provider side. The provider documentation describes audio you can supply as a reference input, which is a different thing from audio the model produces, and reading one as the other is how a wrong number ends up quoted in ten other articles.
So when a comparison tells you H3 "generates audio like Veo 3.1 does", check where that came from. Kavel's own MiniMax H3 page declines to claim it either way, and the Veo 3.1 page documents the audio behaviour that is confirmed.
Both models refund a failed generation automatically on Kavel, unless the run broke the content policy. The credit estimate updates before you commit, so none of the numbers above arrive as a surprise.
Choose MiniMax H3 over Veo 3.1 if…
- You want a fixed 2K frame without thinking about resolution tiers at all.
- Your clip has to run ten seconds in one generation, which Veo 3.1 will not do.
- You are starting from a still image and want the most predictable path from photo to motion.
Choose Veo 3.1 over MiniMax H3 if…
- You need sound in the output without a second pass.
- You are drafting and re-rolling, and do not want length to move the bill.
- You want to anchor a shot with first and last frames, or with up to three image references.
- You need 9:16 for vertical, or 4K for a final cut.
For most people the honest answer is both: draft on Veo 3.1 Lite where iteration is cheap, then reach for MiniMax H3 when the shot needs 2K or an extra two seconds. They share one balance here, so switching is a dropdown rather than a second bill. Run either model now — the estimate shows before you generate.
FAQ: MiniMax H3 vs Veo 3.1
Is MiniMax H3 or Veo 3.1 cheaper?
Veo 3.1 on the Lite tier is cheaper at every length both models offer, because Veo 3.1 bills per video rather than per second. An eight-second clip is about 45 credits on Veo 3.1 Lite against about 253 on MiniMax H3.
Does MiniMax H3 generate audio?
Not confirmed. The provider's documentation covers audio you can supply as a reference input, not audio the model produces, so we do not claim it either way. Veo 3.1 does return sound in the output.
What resolution is MiniMax H3 compared to Veo 3.1?
MiniMax H3 is a fixed 2K with no resolution ladder, so a draft and a final cut cost the same per second. Veo 3.1 lets you pick 720p, 1080p or 4K.
How long can a MiniMax H3 clip be?
5, 6, 8 or 10 seconds on Kavel, against a model ceiling of fifteen seconds. Veo 3.1 runs at 4, 6 or 8 seconds.
Can Veo 3.1 do vertical video?
Yes — Veo 3.1 outputs 16:9 or 9:16, at 720p, 1080p or 4K.
Do I need two subscriptions to use both models?
No. MiniMax H3 and Veo 3.1 draw on one Kavel credit balance, alongside the image models, so there is no second bill for switching between them.
