🤖 Guide: How to Build Your First OpenAI Agent

Building a basic AI agent using OpenAI's platform involves several key steps. First, developers need to clearly define the agent's objective and select an appropriate OpenAI model (such as GPT-4o, o3-mini, or GPT-4.1) based on the complexity of the task and desired latency. After setting up the development environment with an OpenAI API key, clear instructional prompts are crafted to define the agent's behavior, role, and response style. For more advanced functionalities, agents can be equipped with tools like web search, file search, or the ability to call external functions (APIs). Frameworks like OpenAI's Agents SDK or libraries such as LangChain can then be used for orchestrating multi-step tasks, managing memory, and integrating the agent with other applications, followed by thorough testing and iteration.
