Lightweight open video with HunyuanVideo 1.5

Tencent’s 8.3B open video model for coherent motion — T2V and I2V in LazyKiwi.

HunyuanVideo 1.5 (Hugging Face: tencent/HunyuanVideo-1.5) is a lightweight open-source video generation model with about 8.3 billion parameters. Tencent positions it for strong visual quality and motion coherence while remaining efficient enough for consumer-grade GPUs, with unified text-to-video and image-to-video support across 480p/720p checkpoints and optional super-resolution paths. LazyKiwi exposes Hunyuan as a promo-priced workbench model with production duration caps. Specs: up to 480p ≤10s; 720p ≤5s.
