开始你的 AI 之旅

# 我的第一个 AI 程序
from openai import OpenAI

client = OpenAI(api_key="sk-...")

response = client.chat.completions.create(
    model="gpt-4o-mini",
    messages=[
        {"role": "system", "content": "你是一名友好的 AI 助手"},
        {"role": "user",   "content": "用一句话介绍 AI"}
    ]
)
print(response.choices[0].message.content)

# 多模态：让 AI 看图
from openai import OpenAI

             "image_url": {"url": "https://..."}}
        ]

# 流式输出：像打字机一样
stream = client.chat.completions.create(

for chunk in stream:

# 工具调用：让 AI 帮你查天气

                "city": {"type": "string"}
            }
        }

# 然后让模型决定是否调用
