OpenAI is preparing to host its third annual developer conference, DevDay 2025, on Monday. The company states that more than 1,500 people are scheduled to gather at Fort Mason in San Francisco for what OpenAI calls its biggest event yet. The conference will feature announcements, keynotes from OpenAI executives, and a fireside chat between CEO Sam Altman and longtime Apple designer Jony Ive.
DevDay 2025 is shaping up to be a significant display of OpenAI’s rising influence in Silicon Valley as it competes with giants like Apple, Google, and Meta. OpenAI is currently developing an AI device, a social media app, and an AI-powered browser to compete with Chrome. This demonstrates that OpenAI has expanded far beyond its offerings at the first DevDay in 2023, when it primarily had ChatGPT and an API business for developers.
At the same time, OpenAI faces more competition than ever in the effort to win over developers. In the last year, AI models from Anthropic and Google have become increasingly capable for coding and web design tasks. This has forced OpenAI to release better AI models at lower prices to stay competitive. In the background, Meta has assembled an impressive roster of AI talent in its new group, Meta Superintelligence Labs, which could become another threat to OpenAI soon.
At its first DevDay in 2023, OpenAI unveiled a new AI model called GPT-4 Turbo, and Altman shared his vision for a marketplace of AI agents called the GPT Store. Days after that event, Altman was ousted as CEO, only to return after a dramatic weekend of negotiations. In 2024, OpenAI responded with a more subdued conference, announcing meaningful developer upgrades like an API for AI voice applications, but not much else.
Nothing is officially confirmed to launch at DevDay 2025, which has fueled many rumors. OpenAI might finally unveil the AI-powered browser it has been developing, or it may provide an update on the AI device it is building with Ive and former Apple executives. There could also be updates related to the GPT Store, which OpenAI has rarely discussed since its launch several years ago.
DevDay 2025 begins at 10 AM PT on October 6 with an opening keynote from Sam Altman. He is scheduled to share announcements, live demos, and his vision for how developers are reshaping the future with AI. The keynote will last about one hour and will be live-streamed on OpenAI’s YouTube page. This is the only event that will be live-streamed for remote attendees.
For those attending in person, there will be on-stage presentations from Cursor co-founder Aman Sanger, San Francisco Mayor Daniel Lurie, and Andreessen Horowitz Investing Partner Kimberly Tan, among others. Several OpenAI employees will also speak about their work, including model behavior researcher Laurentia Romaniuk and Codex lead Alexander Embiricos.
The event will also feature a series of AI-powered sideshows. One is called “Sora Cinema,” described as a cozy mini-theater with popcorn showcasing short films generated by OpenAI’s video model, Sora. Another exhibit is a phone booth with a living portrait of the famed computer scientist Alan Turing that speaks back.
Later in the afternoon, two major events will conclude DevDay. These final events will not be live-streamed but will be posted on YouTube later that day. At 3:15 PM PT, there will be a Developer State of the Union with OpenAI President Greg Brockman and Olivier Godement, who leads product for the OpenAI Platform. The two executives are slated to demo new capabilities and share what is ahead for developers.
Finally, at 4:15 PM PT, Sam Altman and Jony Ive will hold a Closing Fireside Chat to discuss the craft of building in the age of AI. Their conversation is expected to last about forty-five minutes.
