SGLang-Diffusion Image Generation

Generate images via a local SGLang-Diffusion server's OpenAI-compatible API.

Prerequisites

• SGLang-Diffusion server running (default: http://127.0.0.1:30000)
• If the server was started with --api-key, set SGLANG_DIFFUSION_API_KEY env var

Generate an image

python3 {baseDir}/scripts/generate.py --prompt "a futuristic cityscape at sunset"

Useful flags

python3 {baseDir}/scripts/generate.py --prompt "portrait of a cat" --size 512x512
python3 {baseDir}/scripts/generate.py --prompt "abstract art" --negative-prompt "blurry, low quality"
python3 {baseDir}/scripts/generate.py --prompt "landscape" --steps 30 --guidance-scale 7.5 --seed 42
python3 {baseDir}/scripts/generate.py --prompt "photo" --server http://192.168.1.100:30000 --out ./my-image.png

API 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.py --prompt "hello" --api-key sk-my-key

Or configure in ~/.openclaw/openclaw.json:

{
 skills: {
   "sglang-diffusion": {
     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 PNG in /tmp/.
• Do not read the image back; report the saved path only.
