Helios is a 14 billion parameter autoregressive diffusion model for real-time AI video generation, developed by Peking University, ByteDance, and Canva. It generates video at 19.5 FPS on a single NVIDIA H100 GPU — making it the fastest open-source video model available. Supports text-to-video (T2V), image-to-video (I2V), video-to-video (V2V), and native 1-minute video generation. Released under Apache 2.0 license for commercial use.
Helios is a remarkable technical achievement for the open-source AI video community. However, running a 14B model at 19.5 FPS requires enterprise-grade GPU hardware that most creators cannot access. veo4.dev provides a cloud-based platform where you can access Google Veo 4, Kling AI 3.0, Runway Gen-4, and other top models at cinematic quality — without managing GPUs, CUDA environments, or model weights. Here is how Helios compares to the top AI video platforms.

- Slower quality iteration vs cloud platforms
Wan AI 2.7
Alibaba
Wan AI 2.7 is another strong open-source competitor to Helios — also Apache 2.0 licensed with excellent physics simulation and a large developer community.
Pros
- Apache 2.0 open-source license
- Large developer community and ecosystem
- Strong physics simulation
- Also available on veo4.dev
Cons
- Less real-time speed than Helios
- Different architecture — less suitable for real-time applications
Google Veo 4
Google DeepMind
While Helios is an impressive open-source achievement, Google Veo 4 still leads in absolute cinematic quality, photorealism, and physics accuracy. Available on veo4.dev without any GPU setup.
Pros
- Best-in-class cinematic photorealism
- Perfect physics simulation
- 4K output with audio-visual sync
- No GPU required — cloud-based via veo4.dev
Cons
- Closed source — cannot be fine-tuned
- Requires subscription
Kling AI 3.0
Kuaishou
Kling AI 3.0 offers 4K output, native audio, and 25-second clips — proprietary but available globally. A strong competitor to Helios for those who don't need open-source licensing.
Pros
- 4K output with native audio generation
- 25-second clips with multi-shot mode
- No GPU required
- Available on veo4.dev
Cons
- Closed source — no Apache 2.0 commercial flexibility
- Subscription required

Why Use veo4.dev Instead of Self-Hosting Helios
Helios is a breakthrough for open-source AI video, but most creators get better results with cloud platforms.
No GPU Infrastructure Needed
Helios requires H100 GPUs ($30,000+ hardware or $3-8/hour cloud GPU rental). veo4.dev runs everything in the cloud — access from any browser for $9.9/month.
Instant Setup vs Hours of Configuration
Setting up Helios requires cloning repos, installing CUDA dependencies, and configuring weights. veo4.dev: sign up, get free credits, start generating in 60 seconds.
6 Models vs 1
veo4.dev gives you Helios-quality generation plus Google Veo 4, Kling AI 3.0, Runway Gen-4, and more — all in one platform without managing multiple model deployments.
4K Output on Any Device
Helios quality on H100 hardware. veo4.dev delivers 4K cinematic output from your laptop, phone, or any web browser — no GPU required.
Helios Video Model FAQ
What is Helios AI Video Model?
Helios is a 14 billion parameter autoregressive diffusion model for AI video generation, developed through collaboration between Peking University, ByteDance, and Canva. Released in early March 2026, it is the fastest open-source video generation model available, achieving 19.5 FPS on a single NVIDIA H100 GPU. It supports text-to-video, image-to-video, video-to-video, and native 1-minute video generation. Licensed under Apache 2.0 for commercial use.
What hardware do I need to run Helios?
Helios is optimized for NVIDIA H100 GPUs (80GB VRAM) where it achieves 19.5 FPS. Lower-end GPUs like RTX 4090 (24GB VRAM) can run it at reduced speed. Running at full real-time speed requires enterprise-grade GPU infrastructure costing $3-8/hour on cloud platforms or $30,000+ for local hardware. For most creators, cloud-based platforms like veo4.dev are more practical.
What is the Helios Apache 2.0 license?
Apache 2.0 is one of the most permissive open-source licenses. It allows free commercial use, modification, and distribution of Helios without royalties or licensing fees. You can integrate Helios into commercial products, fine-tune it on proprietary data, and build derivative models. The only requirement is preserving the original license notice.
How does Helios compare to Google Veo 4 in quality?
Google Veo 4 (available on veo4.dev) currently leads in absolute cinematic photorealism, accurate physics simulation, and audio-visual synchronization. Helios is impressive for an open-source model but proprietary models like Veo 4 benefit from larger training budgets and more refined fine-tuning. Helios's key advantages are its open-source nature, Apache 2.0 license, and 1-minute native video length.
Can I fine-tune Helios on my own data?
Yes — this is one of Helios's biggest advantages over proprietary models. The Apache 2.0 license allows you to fine-tune Helios on custom datasets, train it for specific styles or domains, and use the fine-tuned version commercially. This makes Helios particularly valuable for organizations with specialized visual requirements that cannot be met by general-purpose models.
