HunyuanVideo 1.5 is out since 21st of November 2025. It's said to be the top open-source video generator so far.
It's built on DiT and aims to raise the bar for both ease of use and performance.
This version gives sharp visuals and smooth motion and still keeps things easy for devs and creators.
It’s light. With 8.3B parameters it runs on regular GPUs with just 14GB VRAM.
It makes 5 to 10 second videos in 480p or 720p, with support to boost them to 1080p for a more cinematic feel.
By mixing strong results with better hardware use it’s becoming the new standard for open-source tools.
