文生图

curl -X POST http://localhost:9890/v1/images/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_GATEWAY_KEY" \
  -d '{
    "model": "agnes-2.1",
    "prompt": "minimal product photo, soft natural light, clean background",
    "size": "1024x1024",
    "response_format": "url"
  }'

单图参考

{
  "model": "agnes-2.1",
  "prompt": "keep the subject and composition, change to a cinematic poster style",
  "image": "https://example.com/input.jpg",
  "strength": 0.55,
  "size": "1024x1024",
  "response_format": "url"
}

strength 越高，允许偏离原图的程度通常越大。先从中等值测试。

多图参考

  ],
  "size": "1024x1024"
}
