HunyuanVideo
Tencent's open-source video generation model for text-to-video and image-to-video. The 1.5 release (Nov 2025) reaches state-of-the-art quality from just 8.3B parameters, so it runs on a single consumer GPU, with training and LoRA code available. Free, open weights you can self-host or run via providers like fal.

Our take
HunyuanVideo is Tencent's open-source video model for text-to-video and image-to-video. The 1.5 release (Nov 2025) reaches state-of-the-art quality from just 8.3B parameters, so it runs on a single consumer GPU, with training and LoRA code released. Free, open weights to self-host or run via providers like fal. It needs a GPU and setup, but it's among the best open video models.
Best for
Developers, researchers and studios who want a free, self-hostable, commercially usable video model to fine-tune and build on rather than a hosted app.
Pros
- State-of-the-art open video quality for both text-to-video and image-to-video
- 1.5 release runs on a single consumer GPU at just 8.3B parameters
- Fully open weights with training and LoRA fine-tuning code released
- Self-host for free or run via providers like fal; no per-seat lock-in
Cons
- It's a model, not a polished app - expect ComfyUI/GPU setup
- Best results need a capable GPU and some technical know-how
- No built-in editing, UI or support that hosted tools provide
How it compares
Alongside Alibaba's Wan, HunyuanVideo is one of the strongest open-source video models - the appeal over Runway, Kling or Veo is free, self-hostable, fine-tunable open weights.
Full review
HunyuanVideo is Tencent's open-source video foundation model, covering both text-to-video and image-to-video in one framework. The original 13-billion-parameter release set a high bar for open video; the 1.5 update from November 2025 reaches comparable quality at just 8.3 billion parameters, which is the headline - it makes generation practical on a single consumer-grade GPU.
Because the weights are open and the team has released training and LoRA fine-tuning code, studios and researchers can adapt it to their own styles and pipelines rather than renting a closed API. You can self-host it for free or run it through providers like fal. The trade-off is that this is a model, not a finished product: there is no polished UI, and getting good output means a capable GPU and some comfort with tools like ComfyUI. For teams that want control and zero per-seat cost, it is one of the best open options going, alongside Alibaba's Wan.

OpenAI's flagship text-to-video-and-audio model, generating clips with synchronized dialogue and sound effects and improved physical realism. Available via the Sora app and web, free to start with limits and paid tiers for more. Replaced the original Sora, which was retired in April 2026.
Google Veo 3
Google's flagship text-to-video model and the first to generate synced audio - dialogue, effects and ambient sound - in the same pass, with strong physics and prompt adherence. Available in the Gemini apps, the Flow tool and the Gemini/Vertex API. Consumer access via Google AI Pro ($19.99/mo) or Ultra ($249.99/mo); API from $0.40/sec, or $0.15/sec with Veo 3 Fast. Limited free trials in Google AI Studio.
Seedance
ByteDance's AI video generator. Seedance 2.0 (Feb 2026) takes text, images, video and audio together and generates video with native, lip-synced audio in 8+ languages, up to 2K and 4-15 seconds, including multi-shot scenes. Reachable through ByteDance's Dreamina app with free credits and via API platforms.
fal
fal is a serverless platform for running generative media models - image, video, audio and 3D - behind one fast API. Developers call models like FLUX, Wan, Veo and Seedream without managing GPUs, and pay only for successful outputs (for example $0.03 per image, $0.05 per second of video), with no subscription and $20 in free credits to start. It has become a default home for open and commercial media models.
