AI-videokosten ontrafeld: van gratis tot betalen
Wat kost het maken van een AI-video eigenlijk? Dit artikel berekent drie soorten rekeningen: volledig gratis online platforms, lokale open-source modellen, betaalde commerciële tools. Met details over GPU-hardwarekosten, maandelijkse gebruiksraming en een vergelijkingstabel voor selectie op basis van gebruik, die alle routes dekt van nul-kosten experimenteren tot professionele productie. Helpt je met het laagste budget een bevredigend resultaat te halen, rationeel plannen, geen geld verspillen.
How much does AI video cost? From free to $200/month — what's the difference? This article breaks down three cost paths with GPU prices and selection guides.
AI video costs: (GPU/cloud/subscription) and (compute per generation). Three paths: free online (Agnes, zero/zero), local open-source ($800+ GPU or $0.34/hr cloud, near-zero marginal), paid platforms ($7–$200/month).
Author's note: Cost data from the Agnes Video Generator author's experience and public sources (GPU: gpucost.org, cloud: Spheron/Lambda/RunPod, VRAM: official papers). Prices fluctuate — verify before committing.
1. Completely Free: Agnes Video Generator
Zero upfront, zero marginal. Fill in API Key or use Demo page.
- Ready to use: Text-to-video and image-to-video supported. Ideal for promo shots, poetry, e-commerce.
- Zero hardware: Calls Agnes model API, cloud-based, browser-ready.
- Honest boundaries: Up to ~20s per clip, 1 reference image, no cross-shot consistency — great for materials, not long-form.Details atAI Video Tools Complete Guide。

"Free software, not-free hardware." VRAM and duration references for mainstream models:
| Model | VRAM | Duration | Multi-char | Consistency | Notes |
|---|---|---|---|---|---|
| Wan2.1 | ≥24G | 5–10s | ❌ | ❌ | Chinese-friendly, active community |
| HunyuanVideo 1.5 | ≥24G | 5–10s | ❌ | ❌ | Tencent open-source |
| CogVideoX | 16–24G | 6s | ❌ | ❌ | RTX 4090, supports LoRA |
| LTX-Video | ≥16G | 5s | ❌ | ❌ | Near real-time |
| SkyReels-V2 | ≥24G | Up to 60s | ❌ | ❌ | Longest single segment |
GPU Prices (2026 Market)
| Model | VRAM | Price | Notes |
|---|---|---|---|
| RTX 5090 | 32GB | ~$2,000 | Flagship, all models |
| RTX 4090 | 24GB | ~$1,600 | Sweet spot for video |
| RTX 5070 Ti | 16GB | ~$800 | Entry, pruned models |
| RTX 4070 | 12GB | ~$550 | Tight VRAM, quantized only |
Source: gpucost.org (2026), cloud: Spheron/Lambda/RunPod ($0.34–$2/hr). Prices fluctuate — verify before committing.
RTX 4090 is the minimum for local video models. Under $800 without cloud? Local deployment isn't viable — Agnes Video Generator is the zero-investment choice.
3. Paid Industrial Platforms
Subscription/credit platforms for professionals, offering consistency, duration, and audio-visual sync.
| Platform | Price | Duration | Consistency | Best for |
|---|---|---|---|---|
| Sora 2 | ChatGPT Pro (~$200/mo) | 20s, extendable | Character profiles | Pro teams |
| Kling | Credits (~$10/mo+) | 10s, up to 3min | Subject Library 3.0 | Short drama/IP |
| Seedance | Credits | 4–15s, v2.5 30s | Per-character ref | Short video/ads |
| Runway Gen-4 | ~$15–$95/mo | 5–10s | World Consistency | Multi-platform creators |

4. Which Path Should You Take?
Scenario A: Zero budget, first try
→ Free API online (Agnes), zero/zero.
Scenario B: 5–10 videos/week, have GPU
→ Local open-source. $800+ upfront, near-zero marginal.
Scenario C: Commercial, brand films, consistency
→ Paid platforms (Kling/Sora). $10–$200/month for quality and consistency.
5. FAQ
Q：How much does AI video cost?
Three tiers: free (Agnes); $800–$2,000 GPU (open-source); $7–$200/month (industrial).
Q：Completely free generators?
Yes. Agnes Video Generator is free online, no GPU needed. Open-source models are free but need your GPU.
Q：Local vs platform — which is cheaper?
High frequency → local (near-zero marginal). Low frequency → free online (Agnes) or subscription (zero hardware).
Q：Does Agnes charge?
Currently free API. Just fill in your Agnes API Key on the Demo page.
Q：How to calculate costs?
Upfront (GPU/subscription) + marginal (per generation). Free = both zero; local = high upfront, low marginal; industrial = low upfront, pay-per-use.
Q：Lowest cost start for beginners?
Open Agnes Demo, fill Key, three steps. Zero investment; upgrade when needed.
