HunyuanVideo 1.5
Tencent
Lightweight video foundation model from Tencent for high-quality text-to-video and image-to-video generation with strong motion consistency.
Key features
- Text-to-Video Generation: Generates coherent short videos directly from text prompts, optimizing visual fidelity and motion continuity to produce usable outputs for creative and prototyping workflows.
- Image-to-Video (I2V): Converts a single image or set of images into temporally consistent motion/video sequences while preserving appearance and improving frame-to-frame coherence.
- Efficient, Lightweight Architecture: Designed for efficiency (reported ~13B parameters in third-party sources) to reduce inference cost and enable faster generation compared with larger closed-source models.
- Image-Video Joint Training: Trained with a joint image-video strategy and curated datasets to improve spatial detail and temporal dynamics, yielding better motion consistency and fewer artifacts.
- Open-Source Release & Checkpoints: Official repository provides code, pretrained checkpoints, scripts, and examples to run, fine-tune, and extend the model for research and production use.
- Model Variants & Extensions: Provides specialized variants (HunyuanVideo-Avatar for audio-driven human animation, HunyuanVideo-I2V for image-to-video, HunyuanCustom for customization) to cover diverse generation needs.
