Quick Answer: AI video generation costs between $0.15 and $2.50 for a 5-second clip in 2026 — a 17x spread. Seedance 1 Lite, PrunaAI p-video and Hailuo 2.3 Fast are cheapest at $0.03/second; Runway Gen-4.5 and Gen-4 Turbo are most expensive at $0.50/second. OpenAI Sora 2 sits in the middle at $0.10/second. For most product marketing, a $0.06–0.11/second model delivers the best quality-per-dollar.
What AI video actually costs in 2026
Most pricing comparisons repeat vendor marketing pages. This one doesn't. The figures below are the real per-second inference costs we pay to run each of these 26 models in production on PixelMotion — read directly from our model configuration, not from a press release.
That distinction matters, because consumer-facing plans hide the underlying economics behind credits, "generations", and tiers. What follows is the cost floor underneath all of it.
Key definition: Inference cost is what it costs to run one generation on the provider's GPUs. Every AI video tool you can subscribe to pays some version of this number, then adds margin, interface, and storage on top.

The three things this table tells you
1. The premium tier costs 17x more than the budget tier
Runway Gen-4.5 costs $0.50/second. Seedance 1 Lite costs $0.030/second. That is a 16.7x difference for the same nominal output — a 5-second video.
Whether that premium is worth paying depends entirely on where the video will be seen. A hero video on a product page justifies it. Forty product variations for a TikTok test do not.
2. Brand-name models are not automatically the expensive ones
The most counter-intuitive number in the table: OpenAI Sora 2 costs $0.10/second — one fifth the price of Runway Gen-4.5. Sora carries the most consumer name recognition of any video model, and it sits mid-table on cost.
Meanwhile Kling 1.6 Elements ($0.30/s) costs 3x its sibling Kling Video 3.0 ($0.11/s), because Elements is a different architecture solving a different problem (multi-reference composition), not a newer version.
Never infer price from brand. The correlation is weak.
3. "Fast" variants are the value sweet spot
Look at the pattern across model families:
- Hailuo 2.3 Fast: $0.03/s vs Hailuo 2.3 at $0.047/s
- Seedance 2.0 Fast: $0.07/s vs Seedance 2.0 at $0.12/s
- Veo 3.1 Fast: $0.20/s vs Veo 3.1 at $0.40/s
Every "Fast" variant is 35–50% cheaper than its full sibling. For social-format product video — short, vertical, seen on a phone for under 10 seconds — the quality difference is frequently invisible to the viewer, while the cost difference is not.
What this costs you in practice
Inference cost is not retail price. Here is the honest math on what a real workload costs at the infrastructure level:
| Workload | Model choice | Real inference cost |
|---|
| One 5s social clip | Seedance 1 Lite ($0.03/s) | $0.15 | | One 5s hero video | Runway Gen-4.5 ($0.50/s) | $2.50 | | 50-product catalog, 5s each | Kling 2.6 ($0.07/s) | $17.50 | | 50-product catalog, 5s each | Runway Gen-4.5 | $125.00 | | A/B test: 5 variants × 5s | Hailuo 2.3 Fast ($0.03/s) | $0.75 |
The catalog row is the one that matters for e-commerce. Model choice on a 50-product run is a $107 swing — and for thumbnail-sized social video, the cheaper output is often indistinguishable.
How platform pricing relates to these numbers
Any platform reselling these models has to cover inference cost plus margin. PixelMotion's credit system is built directly on the table above: 1 credit = $0.01 of real inference cost, and credit charges are derived programmatically from the same configuration values published here rather than hand-set per model.
PixelMotion plans: a free tier, then $29, $49, $79, and $199/month. The reason to use a platform rather than calling providers directly is not cost — it is that you get all 26 models behind one interface, one bill, and one workflow, instead of 26 API integrations, plus the surrounding pipeline (photo import, enhancement, watermarking, aspect-ratio export, hosting).
If you are generating fewer than a handful of videos a month, direct API access is cheaper. Past that, the integration and maintenance burden is the real cost.
Choosing a model by budget
Under $0.20 per 5-second clip — high-volume social Seedance 1 Lite, PrunaAI p-video, Hailuo 2.3 Fast ($0.15). Use these for volume: variation testing, catalog coverage, short vertical social clips.
$0.25–$0.60 per clip — the default working range Wan 2.6 Flash, PixVerse v5.6, Seedance 1 Pro Fast, Kling 2.6, Kling 2.5 Turbo Pro. This band is where most product marketing should live. Quality is strong enough for paid social, and the cost supports iteration.
$0.50–$1.50 per clip — hero and flagship content Sora 2, Kling Video 3.0, Seedance 2.0, Luma Ray2, Veo 2, Sora 2 Pro. Reserve these for product pages, launches, and paid placements where a single asset will be seen thousands of times.
$2.00–$2.50 per clip — top-end only when justified Veo 3.1, Runway Gen-4 Turbo, Runway Gen-4.5. Real capability, real price. Use deliberately; do not run a catalog through them.
How we got these numbers (and what they do not include)
Methodology, stated plainly so you can judge the figures: every cost above is the per-second rate we are charged to run that model through our inference providers — Replicate and fal — read directly from our production model configuration. They are what a real platform pays per generation, not scraped vendor marketing pages.
Two caveats that matter when you compare this table to other sources:
- These are aggregator prices, not vendor-direct list prices. Running Runway through Replicate is not the same commercial arrangement as buying Runway credits from Runway. Direct-from-vendor pricing, enterprise agreements, and credit-bundle discounts can all differ — sometimes substantially. If you see a different number elsewhere, that is the most likely reason, and it does not make either figure wrong.
- This is generation cost only. It excludes storage, bandwidth, post-processing, and — the big one — failed or discarded generations. In practice your effective cost per usable clip is higher than the sticker rate, because you rarely keep the first output. If it takes three attempts to get a shot you ship, your real cost is roughly 3x the number in this table.
Provider pricing also changes. Treat this as a dated snapshot (July 2026) rather than a permanent quote, and verify before making a large commitment.
Frequently Asked Questions
How much does AI video generation cost per video?
Between $0.15 and $2.50 for a 5-second clip, depending on model. Budget models (Seedance 1 Lite, Hailuo 2.3 Fast, PrunaAI p-video) cost $0.03/second; premium models (Runway Gen-4.5, Gen-4 Turbo) cost $0.50/second. A 10-second clip is roughly double.
What is the cheapest AI video generator?
By raw inference cost, Seedance 1 Lite, PrunaAI p-video and Hailuo 2.3 Fast are joint-cheapest at $0.030/second — $0.15 for a 5-second video. Hailuo 2.3 Fast is notable because it is priced at budget level but classified standard tier.
Is Sora 2 expensive?
No — this surprises people. OpenAI Sora 2 runs at $0.10/second ($0.50 per 5-second clip), which is one fifth the cost of Runway Gen-4.5 at $0.50/second. Sora 2 Pro is $0.15/second. Sora's reputation is built on capability and brand, not on being the premium-priced option.
Are expensive AI video models worth it?
For a single hero asset seen by many people, usually yes. For catalog work or A/B variations, usually not — on a 50-product run at 5 seconds each, choosing Kling 2.6 over Runway Gen-4.5 saves about $107, and at social-feed size the difference is often imperceptible.
What is the difference between "Fast" model variants and the standard version?
Fast variants trade some generation fidelity and controllability for 35–50% lower cost and quicker turnaround. Hailuo 2.3 Fast is $0.03/s vs $0.047/s standard; Veo 3.1 Fast is $0.20/s vs $0.40/s. For short vertical social video the difference is frequently not visible to viewers.
How do credits relate to actual cost?
On PixelMotion, 1 credit equals $0.01 of real inference cost, and each model's credit charge is derived from the same per-second figures in the table above. A 5-second Kling 2.6 generation ($0.35 inference) is charged as 35 credits.
The bottom line
Model pricing in 2026 spans 17x, brand recognition does not predict cost, and "Fast" variants are consistently the best value for social-format product video. Match the model to where the video will be seen: budget tier for volume and testing, mid-tier for the bulk of marketing, premium only for assets that earn their cost back through reach.
