- description
- Generate videos using a local SGLang-Diffusion server (Wan2.2, Hunyuan, FastWan, etc.). Use when: user asks to generate, create, or render a video with a locally running SGLang-Diffusion instance. NOT for: cloud-hosted video APIs or image generation (use sglang-diffusion for images). Requires a running SGLang-Diffusion server with a video model loaded.

SGLang-Diffusion Video Generation
Generate videos via a local SGLang-Diffusion server's OpenAI-compatible API.
Video generation is asynchronous and takes several minutes. The script handles submission, polling, and download automatically.
Prerequisites
- SGLang-Diffusion server running a video model (default:
http://127.0.0.1:30000) - Supported models: Wan2.2-T2V, Wan2.2-I2V, FastWan, Hunyuan
- If the server was started with
--api-key, setSGLANG_DIFFUSION_API_KEYenv var
Generate a video
python3 {baseDir}/scripts/generate_video.py --prompt "a curious raccoon exploring a garden"Useful flags
python3 {baseDir}/scripts/generate_video.py --prompt "ocean waves at sunset" --size 1280x720
python3 {baseDir}/scripts/generate_video.py --prompt "city timelapse" --negative-prompt "blurry, low quality"
python3 {baseDir}/scripts/generate_video.py --prompt "dancing robot" --steps 50 --guidance-scale 7.5 --seed 42
python3 {baseDir}/scripts/generate_video.py --prompt "flying through clouds" --seconds 8 --fps 24 --out ./my-video.mp4
python3 {baseDir}/scripts/generate_video.py --prompt "flying through clouds" --server http://192.168.1.100:30000 --out ./my-video.mp4
python3 {baseDir}/scripts/generate_video.py --prompt "cat playing" --poll-interval 15 --timeout 1800
python3 {baseDir}/scripts/generate_video.py --prompt "animate this scene" --input-image /tmp/scene.pngAPI key (optional)
Only needed if the SGLang-Diffusion server was started with --api-key. Set SGLANG_DIFFUSION_API_KEY, or pass --api-key directly:
python3 {baseDir}/scripts/generate_video.py --prompt "hello" --api-key sk-my-keyOr configure in ~/.openclaw/openclaw.json:
{
skills: {
"sglang-diffusion-video": {
env: { SGLANG_DIFFUSION_API_KEY: "sk-my-key" },
},
},
}Notes
- The script prints a
MEDIA:line for OpenClaw to auto-attach on supported chat providers. - Output defaults to timestamped MP4 in
/tmp/. - Video generation typically takes 5-15 minutes depending on GPU and model size.
- Do not read the video back; report the saved path only.
