Discover how Langchain enhances ChatGPT’s functionality by integrating seamless web search capabilities for AI projects
Langchain Ecosystem: AI Agents Collaborating to Simplify Data Retrieval and Supercharge ChatGPT
Introduction:
Chatbots are becoming increasingly popular, providing users with a convenient way to access information and assistance. With the advent of powerful AI models like GPT-4 from OpenAI, chatbots have become even more intelligent and capable. In this article, we will explore how to enhance your ChatGPTs with web search capabilities using Langchain and SerpAPI. By the end of this article, you will know how to install the required dependencies, understand the basics of Langchain and SerpAPI, and how to use these tools to empower your chatbot.
Installing Dependencies:
To begin, you’ll need to install the following Python packages:
- LangChain: A powerful tool that provides an AgentExecutor chain, allowing your ChatGPT model to perform a web search and return relevant information.
- OpenAI: The official OpenAI API client, enabling you to interact with GPT-4.
To install these dependencies, simply run the following commands in your terminal or command prompt:
pip install langchain
pip install openai
Understanding Langchain and SerpAPI:
Langchain is a Python library that allows you to build an AgentExecutor chain for your ChatGPT model. It allows your chatbot to take specific actions, like performing web searches, analyzing the results, and generating appropriate responses based on the information gathered.
SerpAPI is a Search Engine Results Page (SERP) API that provides an easy way to retrieve search engine results in a structured format. By integrating SerpAPI with Langchain, you can enable your ChatGPT model to search the web and obtain relevant information without manually parsing web pages.
Getting Started:
Once you have installed the required dependencies, you can start building your enhanced chatbot. Here’s a simple example of how to use Langchain and SerpAPI in your ChatGPT model:
from langchain.agents import load_tools, initialize_agent, AgentType
from langchain.llms import OpenAI
import os
os.environ["SERPAPI_API_KEY"] = "your_serpapi_key"
os.environ[''OPENAI_API_KEY''] = "your_openai_key"
llm = OpenAI(temperature=0)
tools = load_tools(["serpapi"], llm=llm)
agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True)
agent.run("According to MarketWatch, what is the price of S&P 500 Future Dec 2024?")
Let’s break it down:
- We import the necessary modules and set API keys for SERPAPI and OpenAI.
- We initialize the OpenAI language model with a temperature of 0 for deterministic results.
- We load the necessary tools (“serpapi”) and create an agent.
- We use the agent’s
run()method to find the price of SPY2024 DEC futures.
The Result:
> Entering new AgentExecutor chain...
I need to find the current price of the S&P 500 Future Dec 2024
Action: Search
Action Input: "S&P 500 Future Dec 2024 price"
Observation: View the latest E-Mini S&P 500 Future Dec 2024 Stock (ESZ24) stock price, news, historical charts, analyst ratings and financial information from WSJ.
Thought: I need to find the current price of the S&P 500 Future Dec 2024
Action: Search
Action Input: "S&P 500 Future Dec 2024 price MarketWatch"
Observation: S&P 500 Index Dec 2024 ; Open $4,403.80 ; Day Range 4,403.80 - 4,403.80 ; 52 Week Range 3,063.70 - 4,463.70 ; Open Interest N/A ; 5 Day. -0.42%.
Thought: I now know the final answer
Final Answer: The current price of the S&P 500 Future Dec 2024 is $4,403.80.
> Finished chain.
''The current price of the S&P 500 Future Dec 2024 is $4,403.80.''
The agent successfully retrieves the current price of the ESZ24 futures ($4,403.80) by intelligently searching the web and extracting the relevant information.
