Cheapest AI Video Generator in 2026: Real Cost Per Second, Every Major Model Compared
The cheapest AI video generator in August 2026 is LTX-2.5 on Soloa at $0.005–$0.02 per second — roughly 5x cheaper than Google's budget Veo tier and up to 29x cheaper than premium models like Seedance 2.5. Across the market, AI video now costs anywhere from half a cent to $0.53 per second depending on model and resolution. Here's every major option, normalized into one table.
AI Video Cost Per Second: Full Comparison (August 2026)
| Model / Platform | Cost per Second | Max Clip | Audio | Best For |
|---|---|---|---|---|
| Soloa — LTX-2.5 | $0.005 (480p) · $0.01 (720p) · $0.02 (1080p) | 20s | ✅ Native | Cheapest on the market; iteration, social content |
| Veo 3.1 Lite (Google) | $0.05 | ~8s | Limited | Enterprise, Google Cloud users |
| Kling 3.0 | ~$0.07 (est. from credits) | ~10s | ✅ | Cinematic look on a subscription |
| LTX-2.5 official API (Fast) | $0.09 (720p) – $0.30 (4K) | 20s | ✅ Native | Developers who need direct API access |
| Sora 2 Standard (OpenAI) | ~$0.10 (720p) | ~15s | ✅ | ChatGPT ecosystem users |

| Seedance 2.5 (ByteDance) | $0.136 (480p) – $0.528 (1080p) | 30s | ✅ | Long single-pass shots, 50 references |
| Veo 3.1 Standard (Google) | $0.40 (with audio) | ~8s | ✅ | Maximum fidelity hero shots |
Methodology: API pay-per-second rates where published (fal.ai, EvoLink, Vertex AI, third-party resellers, August 2026). Subscription platforms (Kling, Pika) are normalized from monthly plan price ÷ included credits, so treat those as estimates. Resolution changes the rate everywhere — we quote 720p–1080p unless noted.
Why "Per Second" Is the Only Honest Metric
Vendors advertise monthly plans, credit packs, and per-clip prices that are hard to compare. Per-second pricing at a stated resolution is the only apples-to-apples number. Two things to watch when converting:
- Credits obscure the real rate. A "$10/month, 660 credits" plan means nothing until you know credits-per-second at your resolution. Do that division before subscribing.
- Resolution multiplies cost. Most platforms charge 2–4x more per second at 1080p vs 480p, and up to 6x at 4K. Generate drafts low, finals high.
The Iteration Tax: Your Real Cost Is 5–10x the Sticker Price
Nobody ships their first generation. A realistic workflow takes 5–10 attempts to get a usable clip — wrong motion, mangled hands, off-brand lighting. That multiplies every sticker price by your retry count:
| Scenario: one finished 15s clip at 720p (8 takes) | Total Cost |
|---|---|
| Soloa LTX-2.5 ($0.01/sec) | $1.20 |
| Veo 3.1 Lite ($0.05/sec) | $6.00 |
| Sora 2 (~$0.10/sec) | $12.00 |
| Runway Gen-4.5 (~$0.12/sec) | $14.40 |
| Seedance 2.5 ($0.293/sec) | $35.16 |
| Veo 3.1 Standard ($0.40/sec) | $48.00 |
This is why per-second cost matters more for creators than leaderboard rank: the model you can afford to iterate on produces better final videos than the model you can only afford to run once. Better prompting also cuts your retry count — our LTX-2.5 prompt guide covers the structure that gets usable clips in fewer takes.
How Soloa Gets to $0.01/sec
LTX-2.5 is an open-weights model — 22B parameters, published on Hugging Face, free to run for organizations under $10M ARR (full deep dive here). Soloa self-hosts it on always-warm servers instead of paying closed-model API margins, and passes the savings on: $0.005/sec at 480p, $0.01/sec at 720p, $0.02/sec at 1080p, included with every subscription at 20–50 generations per day. Text-to-video, image-to-video, and first/last-frame modes, with native audio.
Self-hosting yourself is the other route to cheap video — the weights are free, after all. But once you price in a 16GB+ VRAM GPU (or $0.40–$2/hour cloud rental), setup, and maintenance, hosted-at-cost beats DIY for almost every creator. We break down that math in our open-weight model comparison.
Model-by-Model Pricing Notes
Soloa LTX-2.5 — $0.005–$0.02/sec
The cheapest metered rate on the market. Soloa self-hosts the open-weights LTX-2.5 model on always-warm servers; every subscription includes it with 20–50 generations per day. Native audio, text/image/first-last-frame modes, up to 20-second clips.
Veo 3.1 (Google) — $0.05–$0.40/sec
The widest internal spread: Lite at $0.05/sec is a genuine budget option for enterprise pipelines on Vertex AI, but the Standard tier with audio jumps to $0.40/sec — 8x more. Clips are short, so complex scenes need stitching.
Kling 3.0 & Pika 2.5 — subscription credit systems
Both sell monthly credit bundles (Kling from ~$6.99/mo, Pika from ~$8/mo) that normalize to roughly $0.07/sec and $0.16/sec respectively at standard settings. Fine for casual volume; the credit math punishes heavy iteration months.
Sora 2 & Runway Gen-4.5 — ~$0.10–$0.12/sec
The mid-market: solid quality, ecosystem lock-in (ChatGPT and Runway's edit suite respectively), and pricing that sits 10–12x above Soloa's LTX-2.5 rate.
MiniMax H3 — $0.1625/sec at 2K
Flat rate across text/image/reference modes; a full 15-second clip costs $2.44. The open-weights release (August 2026) lets you self-host the 33B model, but the 2K upscaler remains API-only — details in our open-weight comparison.
Seedance 2.5 — $0.083–$0.528/sec
The premium end. Text-to-video at 1080p is the most expensive mainstream rate in the market ($0.528/sec), justified by 30-second single-pass clips and a 50-input reference system. Full breakdown in our Seedance 2.5 guide.
Monthly Budget Scenarios
| Workload (per month) | Soloa LTX-2.5 | Mid-tier API (~$0.10/sec) | Premium (~$0.30/sec) |
|---|---|---|---|
| Daily 15s social clip (30 finals, ~4 takes each) | $18 | $180 | $540 |
| Weekly 60s YouTube segment (4 finals, ~6 takes) | $14 | $144 | $432 |
| Agency: 100 finished 10s ads (~5 takes each) | $50 | $500 | $1,500 |
When Paying More Is Worth It
Premium models earn their price in specific cases: Seedance 2.5 for 30-second single-pass shots with up to 50 reference inputs, Veo 3.1 Standard for maximum-fidelity hero footage, Runway for its editing ecosystem. The smart pattern is hybrid: iterate at $0.01/sec, finalize on premium only when the shot demands it. Teams doing this typically cut video spend by 80–90% without a visible quality drop in their published content.
5 Ways to Cut Your AI Video Bill
- Draft at 480p, finalize at 1080p. Resolution is the biggest cost multiplier everywhere. On Soloa the spread is $0.005 vs $0.02/sec — iterate cheap, upscale the winner.
- Fix the prompt before the budget. A structured prompt (camera + subject + action + lighting + audio) cuts retries roughly in half. Steal the templates in our prompt guide.
- Generate short, not long. Two tight 8-second clips usually edit together better — and bill less — than one meandering 20-second take.
- Reserve premium models for hero shots. Run the 90% of your content that's social/b-roll/drafts on $0.01/sec, and spend $0.30–$0.53/sec only where the extra fidelity is visible.
- Beware credit expiry. Subscription credits that lapse monthly are a hidden price increase if your output is uneven. Metered per-second pricing only charges for what you render.
Frequently Asked Questions
What is the cheapest AI video generator in 2026?
Soloa's LTX-2.5 at $0.005–$0.02 per second is the cheapest hosted option on the market as of August 2026. The next cheapest, Veo 3.1 Lite, costs $0.05/sec — 5x more at 720p.
How much does a 60-second AI video cost?
At August 2026 rates, a single 60-second generation runs from $0.60 (Soloa LTX-2.5 at 720p) to about $31.70 (Seedance 2.5 at 1080p). With a realistic 5-take iteration cycle, budget 5x those numbers.
Is free AI video generation real?
Free tiers exist but are heavily limited — watermarks, queues, low resolution, and a handful of clips per day. Open-weights models are free to download but need GPU hardware. For sustained output, cheap-per-second beats free-but-capped.
Why is AI video so much more expensive than AI images?
A 10-second 24fps clip is 240 coherent frames plus audio — orders of magnitude more compute than one image. That's also why per-second prices vary 100x between efficient open models and premium closed ones.
Do subscription plans or pay-per-second APIs cost less?
APIs win for occasional use; subscriptions win once you generate regularly. The best value in 2026 is a subscription that meters cheaply per second — Soloa plans include LTX-2.5 at $0.01/sec with 20–50 generations a day.
Bottom line: AI video pricing spans $0.005 to $0.53 per second in August 2026 — a 100x spread. Match the model to the job, iterate cheap, and finalize premium. Start generating at $0.01/sec on Soloa.
