Build with AI: Creating AI Agents with GPT‑5

This repository contains the Python code examples from the LinkedIn Learning course Build with AI: Creating AI Agents with GPT‑5.

You’ll learn how to:

• Build agents that can call tools and take action
• Steer GPT-5 output using verbosity and reasoning settings
• Extend agents with custom tools for more capabilities

Requirements

• Python 3.9+
• An OpenAI API key
• A Weather API key

Setup

1. Clone this repo (or download the files).
2. Create and activate a virtual environment:

   python -m venv venv
   source venv/bin/activate   # macOS/Linux
   venv\Scripts\activate      # Windows

3. Install dependencies:

   pip install -r requirements.txt

4. Set your OpenAI API key or place in .env file:

   export OPENAI_API_KEY="your_api_key"      # macOS/Linux
   setx OPENAI_API_KEY "your_api_key"        # Windows PowerShell

5. Set your Weather API key or place in .env file:

   export WEATHER_API_KEY="your_api_key"      # macOS/Linux
   setx OPENAI_API_KEY "your_api_key"        # Windows PowerShell
