DevDay [2025] is a wrap.

This year, we brought together more than 1,500 developers, founders, and builders at Fort Mason in San Francisco to celebrate what it means to build with OpenAI.

Sam Altman opened the event with the keynote, and we were joined by leaders like Jony Ive, Greg Brockman, and SF Mayor Daniel Lurie to dig into what’s new, what’s possible, and what’s next in AI.

We unveiled powerful new tools for developers, startups, and enterprises —like Sora 2 in the API, apps in ChatGPT, Agent Builder and Agentkit. To everyone who joined — in person or online — thank you. Now, let’s get to building.
