gpt-5.4 识图 - 本地图片

import base64
from openai import OpenAI

client = OpenAI(api_key="sk-xxx", base_url="https://crazyrouter.com/v1")

# 读取本地图片并转为 base64
with open("photo.jpg", "rb") as f:
    image_data = base64.b64encode(f.read()).decode("utf-8")

response = client.chat.completions.create(
    model="gpt-5.4",
    messages=[{
        "role": "user",
        "content": [
            {"type": "text", "text": "这张图片里有什么？"},

Claude 识图

Claude 模型同样支持通过 OpenAI 兼容格式进行识图： 
response = client.chat.completions.create(
    model="claude-sonnet-4-6",
    messages=[{
        "role": "user",
        "content": [
            {"type": "text", "text": "详细描述这张图片"},
            {
                "type": "image_url",
                "image_url": {
                    "url": f"data:image/png;base64,{image_data}"
                }
            }
        ]
    }],
    max_tokens=1024
)

print(response.choices[0].message.content)

支持的识图模型

模型说明
gpt-5.42026 年 3 月 23 日已在生产环境实测成功的 OpenAI 兼容视觉模型
claude-sonnet-4-6已实测成功的 Claude OpenAI 兼容视觉模型
gpt-5.4 与 claude-sonnet-4-6 的视觉输入已于 2026 年 3 月 23 日在 Crazyrouter 生产环境完成实测。图片大小建议不超过 20MB；Base64 编码会增加约 33% 的数据量，大图建议优先使用 URL。
