- Automatically capture Claude Code sessions and OpenClaw agent runs as structured traces
UniVideo
Kling Team (Kuaishou Technology)
Unified video model for understanding, high-fidelity generation, and precise free-form editing via a dual-stream architecture.
Key features
- Dual-Stream Architecture: Combines a Multimodal Large Language Model (MLLM) for understanding instructions with a Multimodal DiT (MMDiT) generator to decouple instruction parsing from video synthesis and preserve visual-temporal consistency.
- Unified Instruction Paradigm: Unifies diverse tasks (text/image-to-video generation, in-context generation, and editing) under a single multimodal instruction format so users can compose complex operations in one prompt.
- In-Context Video Generation: Supports generation conditioned on example frames or short video contexts to produce temporally coherent continuations or variant clips that follow provided examples.
- Free-Form Video Editing: Performs precise edits such as changing materials, green-screening characters, and localized modifications by interpreting free-form multimodal instructions, leveraging transfer from large-scale image editing data.
- Task Composition: Enables combining capabilities (e.g., editing + style transfer) within a single instruction, executing multiple editing and generation steps coherently without separate models.
- Visual-Prompt-Based Generation: Accepts visual prompts (images or video frames) alongside text to guide content, composition, and style of produced videos.
- Joint Multi-Task Training & Checkpoint Variants: Trained jointly across multiple video/image/text tasks and released with checkpoint variants and inference scripts to support different input modalities and research use cases.
- Dual-stream architecture: Multimodal Large Language Model (MLLM) for instruction understanding + Multimodal DiT (MMDiT) for video generation
- Unified capabilities: text-to-video, image-to-video, visual-prompt-based generation, in-context video generation and editing, free-form editing
- Task composition: combine editing, style transfer, and other operations via single multimodal instructions
- Cross-modal transfer: editing capability transferred from image editing datasets to video editing without explicit video-edit training for some tasks
- Model variants / checkpoints: two released variants (Variant 1: img/video/text -> MLLM -> last layer hidden -> MMDiT; Variant 2: img/video/text/queries -> MLLM -> text+queries hidden -> MMDiT)
- Open-source release: code, checkpoints, inference scripts on GitHub and model card on Hugging Face
- Inference utilities: provided demo/inference scripts for running tasks and demos

- Research and Benchmarking: Serve as a baseline and toolkit for academic and industrial research into unified multimodal video models, enabling reproducible experiments with provided code and checkpoints.
