Comparing AI video models Seedance 2.5, WAN 3.0, Flux 3, and MiniMax H3 on price per second and generation quality with the same prompts.
Drafted with Claude from source material, checked by automated verification, and reviewed before release. How we make these.
Which AI video model gives the best value right now? #
Based on API pricing at 720p, MiniMax H3 is the cheapest way to get near-frontier AI video quality, at roughly 8 cents per second, and it’s open source, meaning it can run for free on a decent consumer GPU. Seedance 2.5 sits at the top for raw output quality but costs about 23 cents per second, nearly three times MiniMax H3’s price. Flux 3 and WAN 3.0 land in between, with Flux 3 promising an eventual open-weight release and WAN 3.0 still in beta with projected pricing only.
TL;DR #
MiniMax H3 is the best-value option on the market right now: open source, runnable on consumer GPUs including Macs, and priced around 8 cents per second at 720p.Seedance 2.5 produces the highest-quality footage of the group but costs about 23 cents per second at 720p, a 52% price jump over the original Seedance 2.0.Flux 3 is more expensive than Seedance 2.0 at roughly 17 cents per second, but it’s confirmed for an open-weight release, which should eventually let people run it locally at little to no cost.WAN 3.0 is projected around 10 cents per second in beta, cheaper than Seedance 2.0, but current previews don’t show a huge quality leap, and there’s no confirmed open-source release date.Resolution matters a lot for cost: dropping from 720p to 480p on Seedance 2.5 more than halves the price per second, and AI upscaling has gotten good enough to make that trade-off reasonable.Reference-video jobs get a per-second discount on some models even though they consume far more input tokens, because the raw cost of processing that reference footage is already higher.Price and accessibility are becoming the real differentiator in AI video, not just raw quality, since a model that costs a dollar for five seconds of footage prices out a lot of the hobbyist and indie creator base the technology is supposed to serve.

How does Seedance 2.5 compare to Seedance 2.0? #
Seedance 2.0 was the model that reset expectations for AI video when it launched, despite early availability problems and a slow global rollout. It priced in at about 15 cents per second and was widely regarded as the best AI video model available at the time.
Seedance 2.5 is a real step up in fidelity and prompt adherence in a lot of cases, but it isn’t the kind of leap that 2.0 represented over its predecessors. It’s priced at roughly 23 cents per second at 720p, a 52% increase over Seedance 2.0. For a 5-second generation, that works out to over a dollar, and costs scale up fast from there: a 10-second clip lands around a dollar, and a full minute of footage at 720p runs into several dollars.
Seedance 2.5 does show clear strengths in areas like understanding physical cause and effect (crumbs left on a mouth after eating, debris being cleaned up in a scene) and picking up on subtle motion cues, sometimes to a fault. In one head-to-camera test prompt, the model consistently misread a “whisper in the ear” motion as a kiss, across multiple reroll attempts, suggesting a strong bias baked into its training data around that specific gesture.
Is MiniMax H3 the best budget option? #
Yes, on pure cost-efficiency, MiniMax H3 is hard to beat. It’s already released as open source, priced around 8 cents per second at comparable 720p resolution, or effectively free if you’re running it on your own hardware. It works across a wide range of consumer GPUs, including Macs, which puts genuine AI video generation within reach of people without enterprise-grade compute or a subscription budget.
The quality trade-off is real. H3 output doesn’t match Seedance 2.5 or even Seedance 2.0 in fidelity, and side-by-side test prompts show it taking a rougher, faster-cut approach to scene transitions compared to the smoother pacing of Seedance’s outputs. But for a model that costs nothing to run locally, the gap is smaller than the price difference would suggest, and it’s currently the strongest technologically impressive release in the open-source AI video space.
How does Flux 3 stack up against the paid models? #
Flux 3 is priced above even standard Seedance 2.0, at around 17 cents per second, which puts it above the “value” tier despite lacking image-to-video reference support in some testing. Where Flux 3 pulls ahead long-term is its open-weight future: it’s confirmed to get an open-source release, similar to the treatment MiniMax H3 has already received, meaning distilled versions should eventually run on consumer hardware for a fraction of the API cost.
In direct prompt comparisons, Flux 3 didn’t follow instructions as tightly as Seedance 2.5, and there were noticeable audio and visual quality gaps. But given that it runs locally once released and doesn’t require an initial frame reference the way some competitors do, it offers a different kind of value: pay for API access now, or wait for a free local option later.
What about WAN 3.0? #
#
Plans first. Then code.
Remy writes the spec, manages the build, and ships the app.
WAN 3.0 is still in beta, so its projected price of around 10 cents per second isn’t locked in, but it undercuts Seedance 2.0 on cost. Early previews haven’t shown a dramatic quality jump over prior WAN releases or competing models at similar price points.
The bigger concern is licensing. Previous WAN models had open-source releases, which built a strong community and ecosystem around the series. WAN 3.0 currently has no confirmed open-source release date, and there’s a real possibility it stays closed. If that holds, it would be a significant shift for a model line that built its reputation partly on accessibility, and it could push a chunk of its existing user base toward alternatives like MiniMax H3.
Does resolution change the price-to-quality math? #
Significantly. Seedance 2.5 at 480p costs less than half of what 720p does, roughly 10 to 12 cents per second instead of 23. A 5-second generation drops to around 52 cents, a 10-second clip to about a dollar, and a full minute of footage comes out to roughly $6.24 at 480p versus well over $12 at 720p.
Given how far AI video upscaling has come, generating at 480p and upscaling afterward is a reasonable way to cut costs without a proportional hit to final quality. This matters more as generation length increases, since the cost gap compounds quickly on longer clips.
Frequently Asked Questions #
Which model is cheapest per second of AI video?
MiniMax H3 is the cheapest at around 8 cents per second at 720p, and since it’s open source, it can be run for free on a sufficiently capable consumer GPU.
Is Seedance 2.5 worth the higher price over Seedance 2.0?
It depends on the use case. Seedance 2.5 offers noticeably better handling of physical detail and nuance in motion, but it’s a 52% price increase over 2.0 and the overall leap in quality isn’t as dramatic as the jump from earlier Seedance versions.
Will WAN 3.0 be open source?
As of its beta release, there’s no confirmed open-source or open-weight release date for WAN 3.0, unlike earlier WAN models. This is still unresolved and could change.
Does lowering resolution actually save meaningful money?
Yes. Dropping from 720p to 480p on Seedance 2.5 more than halves the cost per second, and combining that with AI upscaling is a practical way to manage costs on longer generations.
Why do reference-video jobs cost differently per second?
Some models offer a discounted per-second rate for jobs that use a video reference as input, even though those jobs consume far more input tokens overall, since the reference footage itself adds significant processing cost.
