ReAct Agent: Reasoning and Acting with Multiple Tools

Author: Rishabh Srivastava

This repository contains the code for an interactive ReAct Agent that integrates search, comparison, and analysis tools using LangChain, SerpAPI, and Google Vertex AI's Gemini model. The project includes a Gradio-based UI for processing queries and displaying results, with robust error handling and seamless tool transitions.

Features

• Search Tool: Fetches information from the web using SerpAPI.
• Comparison Tool: Compares multiple items based on a specified category using LangChain.
• Analysis Tool: Summarizes and extracts key insights from search and comparison results using Gemini model.
