About

HunyuanCustom is a multi-modal customized video generation framework that emphasizes subject consistency while supporting image, audio, video, and text conditions. Built upon HunyuanVideo, it introduces a text-image fusion module based on LLaVA for enhanced multi-modal understanding, along with an image ID enhancement module that leverages temporal concatenation to reinforce identity features across frames. To enable audio- and video-conditioned generation, it further proposes modality-specific condition injection mechanisms, an AudioNet module that achieves hierarchical alignment via spatial cross-attention, and a video-driven injection module that integrates latent-compressed conditional video through a patchify-based feature-alignment network. Extensive experiments on single- and multi-subject scenarios demonstrate that HunyuanCustom significantly outperforms state-of-the-art open and closed source methods in terms of ID consistency, realism, and text-video alignment.

About

Kling 4.0 is an AI video generation and editing model designed for creating high-quality videos with improved realism, motion, audiovisual synchronization, and creative control. It supports text-to-video, image-to-video, first and last frame control, Omni Reference, and up to 10 keyframe images for directing important moments throughout a generation. Videos can range from 3 to 30 seconds and support resolutions up to 4K, 21:9 ultrawide output, and planned 10-bit HDR at 1080p and 4K. Kling 4.0 can combine as many as 15 reference assets, including images, videos, voice references, and subjects, to guide characters, actions, visual styles, camera movements, composition, and narrative pacing. The model also generates synchronized stereo audio, supports multiple languages and accents, and improves the stability of text, logos, and other visual elements as scenes and camera positions change.
