At its DevDay 2025 on October 6th, the company has announced a new feature called Agent Builder – a transformative tool that can redefine our relationship with AI agents. Up until now, using ChatGPT’s LLMs simply meant entering our plain text prompts and letting ChatGPT handle complex tools in the background.  


However, OpenAI’s Agent Builder fills that valuable gap. It is a visual, no-code platform that enables you to try, design, and deploy AI workflows using a simple drag-and-drop interface. This tool opens a new opportunity for building smart agents without writing a single line of code. This is not just another coding tool. OpenAI Agent Builder is a surprising launch that brings a new paradigm shift.  


Let's dive deep into the details of the newly launched OpenAI Agent Builder, its key characteristics, benefits, real-world applications, and future implications. 


What Is OpenAI Agent Builder? 


OpenAI launched a new visual tool for building multi-step AI agent workflows without starting from scratch. It is an accessible no-code tool launched by OpenAI that enables anyone, regardless of technical experience, to quickly create custom AI agents using natural language and optional integrations. 


These ChatGPT powered agents can perform several tasks such as responding to questions, assisting users in achieving their goals, and handling workflows. You can connect nodes and create agents without writing any code. You can also start with templates or design one of your own. When you are ready, embed the workflow into your site with ChatKit, or download the SDK code to run it yourself.

  • Increased Productivity: By performing repetitive tasks, AI Agents can enhance productivity. It frees humans for more meaningful tasks. 

How to Build AI Agents Using OpenAI 


Here's an easy walkthrough to learn how to build your first AI agent using OpenAI Agent Builder: 


1. Sign in to ChatGPT 


    Make sure to subscribe to ChatGPT Plus or Enterprise plan. 


    • Navigate to “Explore GPTs” panel. 
    • Click on “Create” to begin building your agent.  

    2. Give the Agent an Identity 


    Provide the agent with its name, description, and role. For example; 


    • Name: ResumePro 
    • Description: An AI Agent that assists users with writing and editing resumes.  
    • Instructions: Help users create professional resumes, ask for relevant information, suggest appropriate phrases, and offer formatting tips. 

    3. Configure Tools (Optional) 


    You can add:

     

    • APIs (such as weather, calendar, search). 
    • File upload handlers. 
    • Functions that call backend services. 

    These can help the agent become more useful beyond conversational context and allow it to be more interactive.  


    4. Test Your Agent 


    You can use the built-in test chat window to simulate real interactions. It refines the responses that your agent will provide. 


    5. Allow Memory (Optional) 


    If you want your agent to remember users' personal details, you can enable memory options. 


    6. Share or Publish 


    Once you are satisfied with the agent, you can publish the agent for private use, share it via link, or allow users to find it publicly in the GPT store.  


    Key Components That Power Agent Builder  


    Agent Builder consists of a few elements that support smooth and modular workflow creation:


    • Start Nodes: To set the stage for the agent’s action, set initial conditions and elaborate input parameters.  
    • Classifier Agents: Employ these to direct messages intelligently. For example, a travel agent can make decisions about the query whether it is related to flights or itineraries. 
    • Conditional Logic (If/Else Nodes): This enables your agent to make decisions and take different routes.  
    • Tool Integration: You can connect your agent to web searches, data systems, and APIs to make it sharper and more useful.  

    Real-World Use Cases & Applications 


    Agent Builder is more than a theoretical concept. It is already being applied across many industries:


    • Travel: These agents process flight details, create itineraries list, and respond to customer’s doubts or requests.  
    • Data Analysis: These tools summarize reports and analyze business related information.  
    • Customer Support: These AI agents provide answers to FAQs, generate and manage tickets, while improving service response.  
    • Automation: Agents that handle and perform regular repetitive digital tasks.  
    • Content Creation: These AI agents play the role of writers, editors, and idea generators fueled by visual AI workflows.  

    These real-life examples illustrate AI Agent Builder’s ability to turn imagination into automation.
