Hunyuan Video 混元视频
Tencent's open-weights text-to-video model
Overview
Hunyuan Video is Tencent's text-to-video model, released as open-weights under a permissive license — the largest open-weights video model at release. Used by downstream products and as a backbone for fine-tuning. Tencent Cloud also provides hosted inference.

Use cases
What you can produce with Hunyuan Video 混元视频
- Generate cinematic text-to-video clips at up to 1280x720 resolution and 129 frames using the 13B open-weights model, with camera movements (zoom, pan, tilt, handheld) specified directly in the prompt.
- Animate a still image into a short video using the HunyuanVideo-I2V image-to-video variant (released March 2025), preserving the subject's identity and visual style across frames.
- Create audio-driven talking-head or avatar animations using HunyuanVideo-Avatar (released May 2025), synchronising facial motion and emotional expression to an input audio track of up to 14 seconds.
- Fine-tune the model on a custom visual style or character using the open weights as a backbone, then deploy the resulting LoRA or full fine-tune via ComfyUI or diffusers; 114 community adapter models are already available on Hugging Face.
- Run local inference on a consumer GPU (14 GB VRAM minimum with model offloading for v1.5) to generate 5-10 second clips at 480p or 720p with bilingual Chinese or English text prompts.
- Generate synchronized foley sound effects, music, and vocals for an existing video clip using HunyuanVideo-Foley (released August 2025), the companion open-weights text-video-to-audio model.
- Access the model via third-party API endpoints on fal.ai and Replicate to integrate text-to-video generation into apps or pipelines without managing local GPU infrastructure.

Hunyuan Video is the reference open-weights video model: Tencent ships the actual weights, so teams can self-host, fine-tune, and build on it rather than renting a black-box endpoint. The December 2024 original (13B parameters) needed data-centre GPUs, but HunyuanVideo-1.5 (November 2025, 8.3B) runs on consumer cards with about 14 GB of VRAM, and a step-distilled variant cuts generation time roughly 75% on an RTX 4090. Quality per parameter is the best argument for it. Caveats: the hosted surface is Chinese-language-first, international billing and docs trail Runway, Kling, and Veo, outputs vary run to run, and clips stay short with no timeline editing. Best for ML teams, fine-tuning research, and indie creators comfortable with GPU workflows.
What people say
December 3, 2024 is when open-weights video generation got serious: Tencent released the original HunyuanVideo at 13B parameters — the largest open video model at the time — and claimed wins over Runway Gen-3 and Luma in its own 1,533-prompt human evaluation. The catch was hardware. Full-precision 720p generation wanted around 60 GB of GPU memory, which kept self-hosting in data-centre territory.
HunyuanVideo-1.5, released November 20, 2025, changed the economics. At 8.3B parameters it runs on consumer GPUs with as little as 14 GB of VRAM using model offloading, and Tencent kept shipping through late 2025: a step-distilled 480p image-to-video model on December 5 that cuts end-to-end generation time about 75% on an RTX 4090, FP8 inference support on December 23, and official Hugging Face Diffusers integration. Spin-offs — image-to-video, an avatar model, and the Foley audio model — have made the family a standard fine-tuning backbone, and the ecosystem of adapters, community Spaces, and ComfyUI workflows around it is among the busiest in open video.
The limitations are the category's usual ones plus a few of its own. Faces and backgrounds drift between runs, fast motion and dense crowds lose detail, and there's no timeline editing or dependable camera-direction control — the workflow is prompt iteration. The hosted Tencent surface is Chinese-language-first, and international billing and documentation trail Runway, Kling, and Veo. For self-hosters, fine-tuners, and indie creators, though, this is the open model to beat: nothing else ships this much quality per parameter with weights you can actually download.
