Python：用 AsyncOpenAI 写异步调用

OpenAI 的官方 Python SDK 已经内置了异步客户端 AsyncOpenAI，用法和同步版几乎一样，只是方法前面要 await。

1.单次异步调用

import os
import asyncio
from openai import AsyncOpenAI

# 从环境变量读 API Key
os.environ["OPENAI_API_KEY"] = "你的 key"

client = AsyncOpenAI()

async def main():
    resp = await client.responses.create(
        model="gpt-5",  # 换成你实际用的模型
        input="用一句话解释一下 async/await。",
    )
    # SDK 提供了 output_text 帮你把文本拼好
    print(resp.output_text)

if __name__ == "__main__":
    asyncio.run(main())

2.并发调用多个问题

import asyncio
from openai import AsyncOpenAI

client = AsyncOpenAI()

async def ask(prompt: str) -> str:
    resp = await client.responses.create(
        model="gpt-5",
        input=prompt,
    )
    return resp.output_text

async def main():
    prompts = [
        "帮我想三个团队建设活动",
        "解释一下什么是 Transformer 模型",
        "给我五个产品取名的备选方案",
    ]

    # 构造一堆 task 并发执行
    tasks = [ask(p) for p in prompts]
    results = await asyncio.gather(*tasks)

    for i, answer in enumerate(results):
        print(f"\n=== 问题 {i+1} ===")
        print(answer)

asyncio.run(main())
