OpenAI announced its third annual DevDay conference on July 23, 2025, scheduled for October 6, 2025 at Fort Mason in San Francisco, targeting "more than 1,500 developers for our biggest DevDay yet."
The company describes developers as "central to OpenAI's mission to ensure AGI benefits all of humanity" and positions DevDay as celebrating developers who have "used our tools to build first-of-their-kind products, launch startups, accelerate research, and reimagine what software can do."
Confirmed speakers include "Sam Altman, Chief Executive Officer, Greg Brockman, President, and many more to come." OpenAI states attendees will "get an early look at what's coming next from OpenAI, hear directly from our research, product and engineering teams, and connect with peers and industry leaders to push the field forward."
Registration requires application through July 30, with OpenAI noting that "space is limited" and attendees will be notified "by mid-August" with "one week to register." The event carries a "$650" attendance cost.
For broader accessibility, OpenAI announced that "the keynote will be livestreamed on openai.com, and all other sessions will be recorded and shared afterward" for those unable to attend in person.
The conference represents OpenAI's annual developer engagement initiative, combining product announcements, technical sessions, and networking opportunities for the AI development community.
DevDay 2025 targets 1,500 developers with early access to OpenAI developments, research insights, and product roadmaps, positioning the event as a key engagement platform for enterprise developers building AI-powered applications and solutions.
OpenAI's expanded DevDay demonstrates the company's commitment to developer community engagement and ecosystem growth. The event's scale increase and structured registration process reflect growing developer interest in OpenAI's platform, while livestreaming and session recordings ensure broader reach for product announcements and technical guidance across the development community.
