Agentic OpenAI Chatbot

Overview

This chatbot leverages OpenAI's language models (GPT-4o-mini) alongside Azure Cognitive Search, Bing Web Search, and weather APIs to provide comprehensive answers. It combines internal document search, real-time web data, and weather information to address user queries.

Key Features

1. Multi-Source Information Retrieval:

   • Azure Cognitive Search: Searches internal documents using hybrid semantic/vector search.
   • Bing Web Search: Fetches recent web results (past week) for up-to-date information.
   • Weather API: Provides current temperature data based on coordinates.

2. Agentic Workflow:

   • Automatically selects the appropriate tool (document/web/weather search) based on user input.
   • Uses OpenAI's model to generate responses augmented by tool outputs.

3. Streamlit Interface:

   • Simple web UI for user interaction with a trace sidebar showing tool execution details.

How It Works

1. User Input:

   • Submit a query via the Streamlit interface.

2. Tool Selection:

   • GPT-4o-mini determines which tool(s) to use (document search, web search, or weather lookup).

3. Data Retrieval:

   • Document Search: Generates embeddings for semantic/vector search in Azure.
   • Web Search: Queries Bing for recent results.
   • Weather: Fetches temperature data from Open-Meteo.

4. Response Generation:

   • Combines tool outputs with language model capabilities to form a natural language answer.

Example Use Cases

• Internal Knowledge: "What's the company's 2023 revenue?" (uses Azure document search)
• Current Events: "Latest news on climate change?" (uses Bing web search)
• Weather: "What's the temperature in Paris?" (requires user-provided coordinates)

---

Limitations

• Weather tool requires manual latitude/longitude input (not geocoded from location names).
• No error handling for invalid API credentials or network issues.
• Bing search results limited to 10 items and 1-week freshness.
