【GPT入门】第39课 OPENAI官方API调用方法

1. OPENAI 免费API

需要科学上网，可以调用 gpt-4o-mini 的 api, 使用其它旧的GPT，反而可能需要收费，例如 gpt-3.5-turbo

2. openai调用最简单的API

from openai import OpenAI
import os
OPENAI_BASE_URL = 'https://api.openai.com/v1'

client = OpenAI(
    api_key="sk-proj-xxxxx", # 改为自己的key
    base_url=OPENAI_BASE_URL,
)

completion = client.chat.completions.create(
    model="gpt-4o-mini",# 免费
    # model="gpt-3.5-turbo", # 需要充值
    store=True,
    messages=[
        {"role": "user", "content": "write a 笑话 about ai"}
    ]
)

print(completion.choices[0].message)

3.apiKey提取到环境变量

OPENAI_BASE_URL，OPENAI_API_KEY 这两个变量可以配置到环境变量

from openai import OpenAI
import os


os.environ["OPENAI_BASE_URL"] = 'https://api.openai.com/v1'
os.environ["OPENAI_API_KEY"] = "sk-proj-lWXxxx" #替换为自己的API_KEY
client = OpenAI()

completion = client.chat.completions.create(
    model="gpt-4o-mini",# 免费
    # model="gpt-3.5-turbo", # 需要充值
    store=True,
    messages=[
        {"role": "user", "content": "write a 笑话 about ai"}
    ]
)

print(completion.choices[0].message)
