OpenAI is gearing up to host its third-ever annual developer conference, DevDay 2025, on Monday. The company says more than 1,500 people are scheduled to convene at Fort Mason in San Francisco for OpenAI’s “biggest event yet,” which features announcements, keynotes from OpenAI executives, and a fireside chat between CEO Sam Altman and longtime Apple designer Jony Ive.
From the sound of it, DevDay 2025 is shaping up to be a grand display of OpenAI’s rising dominance in Silicon Valley against giants like Apple, Google, and Meta. OpenAI is currently building an AI device, a social media app, and an AI-powered browser to take on Chrome. In other words, OpenAI has a lot more going on than it did during its first DevDay in 2023, when it mostly just had ChatGPT and an API business for developers to access its models.
At the same time, OpenAI faces more competition than ever in the bid to win over developers.
In the last year, Anthropic and Google’s AI models have become increasingly capable for coding tasks and web design. OpenAI has been forced to release better AI models at lower prices to remain in the race. In the background, Meta has built up an impressive roster of AI talent in its new group, Meta Superintelligence Labs, which could become another threat to OpenAI in the near future.
OpenAI unveiled at its first DevDay in 2023 a new AI model, GPT-4 Turbo, and Altman shared his vision for a marketplace of AI agents called the GPT Store. Altman was ousted as CEO days later — only to return after a dramatic weekend of negotiations. In 2024, OpenAI responded with a more subdued conference, announcing some meaningful developer upgrades, such as an API for AI voice applications, but not much else.
Nothing is confirmed to launch at DevDay 2025, stoking plenty of rumors. Perhaps OpenAI will finally unveil the AI-powered browser it’s been working on, or maybe give an update on the AI device it’s building with Ive and former Apple executives. It’s also possible there could be some updates related to the GPT Store, which OpenAI has barely discussed since it launched several years ago.
News will be on the ground in San Francisco covering the event live, so you can check back here for all the news. Here’s what you need to know about OpenAI’s DevDay, and how to watch it.

DevDay 2025 kicks off at 10am PT October 6 with an opening keynote from Altman, in which he’s scheduled to unveil “announcements, live demos, and a vision of how developers are reshaping the future with AI.” The keynote will last roughly one hour, and will be live streamed on OpenAI’s YouTube page.
That’s the only event that will be live streamed for remote attendees.
For in-person attendees, there will be on-stage presentations and talks 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 give speeches about their work, including model behavior researcher Laurentia Romaniuk and Codex lead Alexander Embiricos.
There’s also supposed to be a series of AI-powered sideshows at DevDay 2025. One of them is “Sora Cinema,” which is described as a “cozy mini-theater with popcorn” featuring short films generated by OpenAI’s video model, Sora. There’s also supposed to be a phone booth with a “living portrait” of the famed computer scientist Alan Turing “that speaks back.”
Later in the afternoon, there will be two big events to cap off DevDay. These last two events won’t be live streamed, but they 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 heads up product for the OpenAI Platform. The two OpenAI executives are slated to “demo new capabilities” and share what’s ahead for developers.
Finally, at 4:15 pm PT, Altman and Ive will give a “Closing Fireside Chat” to discuss the “craft of building in the age of AI.” That conversation will last about 45 minutes.
