From the model card
WeVisCut is a 9B tool-using agent that turns knowledge articles or narration scripts into multi-minute edited videos. At each step, it reads the current editing state and selects one of 12 tools for planning, narration, asset retrieval, composition, inspection, or repair. It is not a standalone text-to-video model; use it with the WeVisCut runtime, which executes the model's tool calls.
Requirements: Python 3.11 or later and an NVIDIA GPU with about 24 GB of memory for bf16 inference. Install a PyTorch build compatible with your CUDA version before the GPU requirements below. The setup script installs Node.js, FFmpeg, and the renderer.
git clone https://github.com/Tencent/WeVisCut.git
cd WeVisCut
pip install -r requirements.txt
pip install -r requirements-gpu.txt
bash scripts/setup_external_tools.sh
pip install -U "huggingface_hub[cli]"
hf download tencent/WeVisCut --local-dir checkpoints/weviscut-9b
bash run_studio.sh
Open http://:8081/ to use the Studio. For UI-only mode without loading model weights, run bash run_studio.sh --no-model.
The policy is based on Qwen3.5-9B and is trained on executable editing trajectories. Its runtime provides an editable timeline with pause/resume, manual and chat-based revisions, per-shot rerendering, and version rollback. Video quality depends on the configured retrieval, TTS, and rendering services and available templates.
WeVisCut is intended for research and production assistance in long-form video editing. It does not guarantee factual accuracy or production quality; review generated narration and video before publication. The model weights require the WeVisCut tool environment to produce a video.
