Companion open releases extend the family: HunyuanVideo-I2V (image-to-video), HunyuanVideo-Foley (audio), and HunyuanVideo-Avatar. Read the license terms carefully before commercial use — it’s more restrictive than a standard open-source license.
Tencent Hunyuan Video
by Tencent
Tencent's open-weight video foundation model — over 13B parameters, released with code and weights.
- Original release (Dec 2024): 13B+ parameters, described by Tencent as the largest open-source video model at the time
- HunyuanVideo-1.5, a lighter 8.3B variant, targets consumer-GPU inference
- Ships under a restrictive Tencent Community License — excludes EU/UK/South Korea, requires a separate license above 100M monthly active users
- Requires roughly 60GB GPU memory to run the original full model locally
