下面这些模型是langchain集成了高级功能的模型,基本都是国外模型,虽然所有这些 LangChain 类都支持指定的高级功能,但您可能有 打开特定于提供程序的文档,了解哪些托管模型或后端支持 该功能。

我们需要怎么从langchain导入模型,通常是需要模型的api进行导入,api要自行准备,通过设置为环境变量,下面演示一下谷歌的gemini和国内的deepseek

如果要导入对应大厂的模型,需要先安装对应模型的langchain包,首先来演示gemini:

pip install -qU "langchain[google-genai]"
import os
from dotenv import load_dotenv
from langchain.chat_models import init_chat_model
os.environ["GOOGLE_API_KEY"] = ""#输入你的api_key,或者可以输入到.env文件放在同一目录下
load_dotenv(override = True)
GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY")
model = init_chat_model("gemini-2.5-flash",model_provider="google_genai")

接着到deepseek的,依然需要安装对应包,其他模型类似

pip install langchain-deepseek
import os
from detenv import load_dotenv
from langchain.chat_models import init_chat_model
os.environ["DEEPSEEK_API_KEY"] = ""#填写你的api_key
load_dotenv(override = True)
DeepSeek_API_KEY = os.getenv("DEEPSEEK_API_KEY")
model = init_chat_model(model = "deepseek-chat", model_provider = "deepseek")
