Setup
Requires Zhipu AI credentials in .baoyu-skills/.env:
OPENAI_API_KEY=<your-zhipu-api-key>
OPENAI_BASE_URL=https://open.bigmodel.cn/api/paas/v4/
API Endpoint
POST https://api.z.ai/api/paas/v4/images/generations
Usage
The agent should call baoyu-image-gen with OpenAI provider pointing to Zhipu AI:
npx -y bun <baoyu-image-gen-path>/scripts/main.ts \
--provider openai \
--model glm-image \
--prompt "<prompt>" \
--image <output.png> \
--ar 3:4 \
--quality 2k
Or via curl:
curl --request POST \
--url https://api.z.ai/api/paas/v4/images/generations \
--header 'Authorization: Bearer <token>' \
--header 'Content-Type: application/json' \

"prompt": "A cute little kitten sitting on a sunny windowsill",
"size": "1280x1280"
}'
