图像理解

Python

import anthropic

client = anthropic.Anthropic(api_key="your-api-key", base_url="https://www.cheapertoken.work")

# 使用图片 URL
response = client.messages.create(
    model="claude-opus-4-7",
    max_tokens=1024,
    messages=[
        {
            "role": "user",
            "content": [
                {
                    "type": "image",
                    "source": {"type": "url", "url": "https://example.com/image.jpg"},
                },
                {"type": "text", "text": "请描述这张图片"},
            ],
        }
    ],
)
print(response.content[0].text)
