Estimated reading time: 3 minutes

OpenAI DevDay 2025 kicked off in San Francisco, bringing together over 1,500 developers for the company’s largest event ever. Sam Altman and Jony Ive headlined the stage. They revealed powerful new tools poised to change how AI apps are built. The energy was palpable, driven by a promise: “It’s the best time in history to be a builder”.

OpenAI AgentKit: Toolkit for AI Agents

Building Smarter Agents is Now Easier

The showstopper was OpenAI Agent Kit, a set of core capabilities that helps developers create, test, and deploy agent workflows from start to finish. With its visual Agent Builder, anyone can design agents without diving into code. The drag-and-drop interface simplifies logic, step sequencing, and version control for multi-agent setups. Furthermore, the integrated Connector Registry allows agents to hook safely into your apps and enterprise systems.

AgentKit expands OpenAI’s ecosystem to make deploying agents frictionless. Its ChatKit feature lets developers embed customizable chat agents directly in websites and apps. Besides, new admin controls help manage connectors and access, especially for enterprise projects.

Jony Ive says pace of change in AI is “extraordinary”!

Apps and Models: Turbocharged for OpenAI DevDay 2025

ChatGPT Apps and Enterprise Features

This year, OpenAI made it possible to build and run apps directly inside ChatGPT. Major brands like Canva, Expedia, Coursera, Spotify, and Booking.com have already launched integrations, letting users talk to apps within the chat interface. That means users get direct access to services, information, and even purchases – all in one place.

Enterprise teams benefit from added controls, like tenant isolation and private networking, ensuring secure AI deployment. New admin dashboards and data retention policies help organizations adapt AI safely and quickly.
