LangChain

LangChain 是一个开源框架，提供预构建的智能体架构以及适用于任何模型或工具的集成。 官方网站：langchain.com

1.1 使用方法​

方式一：直接参数配置（推荐）​

from langchain_openai import ChatOpenAI

llm = ChatOpenAI(
    openai_api_base="https://api.luchentech.com/inference/v1",
    openai_api_key="your-luchentech-key",
    model="minimax/minimax-m2.5"
)

response = llm.invoke("Hello!")
print(response.content)

方式二：环境变量​

import os
os.environ["OPENAI_API_BASE"] = "https://api.luchentech.com/inference/v1"
os.environ["OPENAI_API_KEY"] = "your-luchentech-key"

from langchain_openai import ChatOpenAI
llm = ChatOpenAI(model="minimax/minimax-m2.5")

方式三：JavaScript/TypeScript​

import { ChatOpenAI } from "@langchain/openai";

const llm = new ChatOpenAI({
  baseURL: "https://api.luchentech.com/inference/v1",
  apiKey: "your-luchentech-key",
  model: "minimax/minimax-m2.5"
});

方式四：在智能体中使用​

from langchain_openai import ChatOpenAI
from langchain.agents import AgentExecutor, create_openai_functions_agent
from langchain import hub

llm = ChatOpenAI(
    openai_api_base="https://api.luchentech.com/inference/v1",
    openai_api_key="your-luchentech-key",
    model="minimax/minimax-m2.5"
)

prompt = hub.pull("hwchase17/openai-functions-agent")
agent = create_openai_functions_agent(llm, tools, prompt)
agent_executor = AgentExecutor(agent=agent, tools=tools)

result = agent_executor.invoke({"input": "Your question"})
