Last month, OpenAI held one of the biggest AI conferences of the year: DevDay 2025. The conference’s focus was to introduce new AI tools, especially those that make development faster and easier. What was the most eye-catching feature? In my opinion…AgentKit.

AgentKit is a user-friendly, non-technical way to build agents “from prototype to production.” Even the very presentation of AgentKit was impressive, with the speaker demo’ing the use of AgentKit to build an entire agent live in front of the audience within just 8 minutes. To put that into perspective, building a high-quality agent manually can take several months, so 8 minutes really does feel like the blink of an eye compared to that.

At first, it seemed impossible that AgentKit (or any AI tool for that matter) could streamline the agent-building process that significantly, but as I soon learned, AgentKit achieves much of its speed from the fact that it uses agent-building development patterns that have been observed in OpenAI employees themselves. In other words, it’s literally learning from some of the best agent-builders in the world!

Furthermore, the tool is exceedingly easy to use. If you can click and drag blocks (called “nodes”), then you can build an agent! For example, you can add an “Agent” node and provide it with a document of pre-filled information (like a guest list or an event program), and it will use the given material to answer user questions, effectively being able to fulfill many roles, be it customer service, tech support, traveling advisor, or more.

You can also use OpenAI’s Widget Builder to make the agent visually interesting (because who wants to just look at lines and lines of plain text??). And adding a “Guardrails” node will allow you to secure your agent. You can have users enter their name, phone number, location, and/or any other combination of Personally Identifiable Information (PII) that you (the agent-builder) would like to include to protect the agent from scammers or malicious individuals.

Below is a list of companies and organizations already using AgentKit and some of the interesting ways in which agents are being increasingly used:

• Actively – GTM Intelligence Agent
• Albertsons – Merchandising Intelligence Agent
• Bain & Company – Code Modernization Agent
• Box – Customer Onboarding Agent
• Canva – Support Agent
• Evernote – Work Assistant Agent
• HubSpot – Breeze AI Agent
• LegalOn Technologies – Policy Agent
• Ramp – Buyer Agent
• Rippling – Sales Briefing Agent

I promise you, this isn’t a paid endorsement (or an endorsement of any kind)! I’m just excited by what tools like AgentKit could open the doors for. Remember, with AgentKit, months become minutes.
