Open-source video generation at up to 70% lower cost
Runway's Gen-3 is the quality leader for AI video. Fleek is up to 70% cheaper running open-source models (LTX-2, Kling 2.1) that approach Gen-3 quality. Use Runway for marketing and premium content. Use Fleek for volume, prototyping, and cost-sensitive applications.
Runway pioneered AI video generation with their Gen series. Gen-3 Alpha produces impressive results—smooth motion, good prompt adherence, professional quality. It's the benchmark for video AI.
But Runway's pricing reflects that quality leadership. Their credit-based system can get expensive at scale, especially for longer clips. Fleek takes a different approach: we run open-source video models like LTX-2 and Kling at GPU-second pricing.
This comparison is about tradeoffs. Runway has the best proprietary model. Fleek has the best pricing on open-source alternatives. The right choice depends on your quality requirements and budget.
| Model | Fleek | Runway | Savings |
|---|---|---|---|
| Runway Gen-3 AlphaCredit-based pricing | N/A | $0.50-1.00 per 5s | N/A |
| LTX-2 (on Fleek)Open-source alternative | ~$0.08 per 5s | N/A | ~70% vs Gen-3 |
| Kling 2.1 (on Fleek)Available on multiple platforms | ~$0.20 per 5s | $0.32 per 5s (fal) | 38% |
Runway uses a credit system. Actual cost per second varies by resolution and model version. Open-source models have narrower quality gaps than many expect.
Fleek runs open-source video models at $0.0025 per GPU-second. Models like LTX-2 and Kling 2.1 have improved dramatically and produce usable results for many applications.
We don't run Runway's proprietary Gen-3—that's only available through Runway. But for applications where open-source quality is sufficient, we're dramatically cheaper.
Runway offers Gen-1, Gen-2, and Gen-3 video models through their web interface and API. Gen-3 Alpha represents the state of the art in AI video generation, with smooth motion and excellent prompt adherence.
Pricing uses a credit system. Credits cost $0.01-0.05 depending on volume, and generation costs vary by model and resolution. Their web interface is excellent for creative workflows.
Gen-3 isn't available outside Runway. Migration means switching to open-source models (LTX-2, Kling), which have different characteristics. Quality testing is essential before switching production workflows.
Gen-3 Alpha is still the quality leader with smoother motion and better prompt adherence. LTX-2 is catching up and produces usable results for many applications, especially at up to 70% lower cost. The gap is narrowing with each release.
No, Gen-3 is Runway's proprietary model only available through their platform. Fleek runs open-source alternatives like LTX-2 and Kling 2.1.
For premium marketing content where quality directly impacts brand perception, Runway Gen-3 is the safer choice. For social media, prototypes, or volume content, Fleek's open-source models often suffice at much lower cost.
Fleek supports the capabilities of the underlying models. LTX-2 and Kling have different video-to-video features than Runway. Check specific model capabilities before assuming feature parity.
Coming soon. We're building support for any model—not just the open-source ones we showcase. Upload your custom video model, and we'll apply the same optimization. Same $0.0025/GPU-sec pricing, no custom model premium. Launching in the coming weeks.
This is genuinely a quality vs cost tradeoff. Runway Gen-3 produces better video. Fleek is up to 70% cheaper on open-source alternatives.
For professional content, marketing, and anywhere quality directly impacts results, Runway's premium is often justified. For prototyping, scale applications, and cost-sensitive use cases, open-source models on Fleek deliver solid results at a fraction of the price.
The gap between Gen-3 and open-source models is shrinking. Test both on your actual use case—you might be surprised how close the open-source options have gotten.
Note: Fleek is actively expanding model support with new models added regularly. Features where competitors currently have an edge may become available on Fleek over time. Our goal is universal model optimization—supporting any model from any source at the lowest possible cost.
