## 图生图

传入参考图片进行风格迁移或增强：

```python theme={null}
# 图片 URL
response = client.chat.completions.create(
    model="banana-lite",
    messages=[{
        "role": "user",
        "content": [
            {"type": "text", "text": "Turn this photo into a Studio Ghibli style illustration"},
            {"type": "image_url", "image_url": {"url": "https://example.com/photo.jpg"}}
        ]
    }],
    max_tokens=1000
)
```

```python theme={null}
# Base64
import base64

with open("input.jpg", "rb") as f:
    encoded = base64.b64encode(f.read()).decode("utf-8")

response = client.chat.completions.create(
    model="banana-lite",
    messages=[{
        "role": "user",
        "content": [
            {"type": "text", "text": "Apply pixel art style"},
            {"type": "image_url", "image_url": {"url": f"data:image/jpeg;base64,{encoded}"}}
        ]
    }],
    max_tokens=1000
)
```
