1.调用具体模型的厂商API

1.调用具体模型的厂商API

调用大模型涉及道三个重要的参数base_url,model_name,api_key
调用成功

代码

import os
from urllib import response

from dotenv import load_dotenv
from langchain_deepseek import ChatDeepSeek
from pydantic_settings.sources.providers import dotenv
from typing_extensions import override

#读取.env中的配置文件,相关的环境变量以.env文件中优先
load_dotenv(override=True)

DEEPSEEK_API_KEY=os.getenv("DEEPSEEK_API_KEY")
DEEPSEEK_BASE_URL=os.getenv("DEEPSEEK_BASE_URL")

llm_deepseek=ChatDeepSeek(
    model="deepseek-v4-flash",
    api_key=DEEPSEEK_API_KEY,
    api_base=DEEPSEEK_BASE_URL,
)

response =llm_deepseek.invoke("邓紫棋")
print(response)

配置文件.ENV
