图片生成调用指南

通过统一网关调用 GPT-Image-2、Gemini Image、字节即梦 Seedream 等图片生成模型。

模型清单

模型 ID	厂商	特点
gpt-image-2	OpenAI	风格自由度高、prompt 理解强
gemini-3.1-flash-image	Google	速度快、风格多样
gemini-3-pro-image	Google	质量更高
doubao-seedream-4-0	字节	中文 prompt 友好

调用代码

Python

from openai import OpenAI

client = OpenAI(api_key="sk-xxx", base_url="http://xdhdancer.top/v1")

resp = client.images.generate(
    model="gpt-image-2",
    prompt="a cyberpunk cat sitting on a neon-lit rooftop, 4k illustration",
    size="1024x1024",
    n=1,
)
print(resp.data[0].url)

curl

curl http://xdhdancer.top/v1/images/generations \
  -H "Authorization: Bearer sk-xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-image-2",
    "prompt": "minimalist mountain at sunrise",
    "size": "1024x1024"
  }'

Prompt 撰写技巧

1. 主体清晰：a robot 优于 something cool
2. 风格描述：4k illustration / cinematic / oil painting
3. 环境光线：neon-lit / sunset / dramatic lighting
4. 构图：close-up / wide shot / isometric view

例：

a futuristic city skyline at sunset, cyberpunk aesthetic, 
neon signs reflecting on wet streets, cinematic wide shot, 
ultra-detailed, 8k
