OpenAI is holding its DevDay 2025 event today, Oct. 6, and the company has already teased that it has a host of product launches under its sleeve. While it's geared toward developers, the company also typically announces updates to its consumer products, including ChatGPT.
This event follows closely on the heels of OpenAI's major product announcements last week, including its highly anticipated Sora 2 model and accompanying new iOS app, as well as a new agentic Instant Checkout e-commerce feature. Since OpenAI didn't hold that news for today's event, it probably means today's announcements will be even bigger.
For information on how to watch, what to expect, and live updates of the event as it unfolds, you can follow the live blog below, updated throughout the day from the venue.
Demos of Apps SDK
By Sabrina Ortiz, Senior Editor / Oct. 6 at 1:30 p.m. ET
Alexi Christakis, software engineer at OpenAI, led a live demo showcasing an app in action within the ChatGPT interface. In this example, he opened the Coursera app, which populated a video from the learning platform right within the chat. From there, a user can ask follow-up questions in a process OpenAI called "talking to apps."
In this case, Christakis talked to ChatGPT regarding the video's contents. In another example, he asked Canva to help create a poster -- within the interface, Canva was able to output four poster examples in line. They were accompanied by an explanation of what ChatGPT did. The App SDK also gives access to full-screen within ChatGPT.
To push the limits even further, Christakis asked ChatGPT to create a pitch deck from the poster, which got "ooo's" and "ah's" from the audience. As that was happening, he moved on to another prompt, asking ChatGPT what city he should bring the pretend project to, where he called on Zillow to help find homes in the area. Then the Zillow experience became available within ChatGPT.
To filter the Zillow results down, Alexi just had to type in a natural language prompt, showing how users could narrow down results using text as opposed to having to mess with filters on the Zillow website. By then, the slide deck was finished and looked very polished. Christakis was able to view it in full-screen. From here, users could then tweak the slides further through other prompts and open them in Canva.
The App SDK is available in preview starting today for developers. Later this year, developers will be able to submit apps for review to be listed.
Apps inside ChatGPT
By Sabrina Ortiz, Senior Editor / Oct. 6 at 1:15 p.m. ET
Sam Altman opened up DevDay with a breakdown of the coming announcements, which fall into four categories: apps inside ChatGPT, Building agents, writing code, and API updates.
We're starting with apps inside ChatGPT. OpenAI is making it easier for developers to build in ChatGPT by launching the Apps SDK. This gives developers access to the full stack, allowing them to build actual apps as opposed to previous methods such as GPTs, plus it uses Anthropic's Model Context Protocol (MCP).
There is excitement from developers in the room over the opportunity to monetize.

What to expect from OpenAI DevDay
Since the event is geared towards developers, there will likely be a lot of news specifically targeted at them, such as updates on how to build. Sam Altman posted on X that the company has "got some new stuff to help you build with AI." This lines up with reports saying that OpenAI will be launching an Agent Builder.
Additionally, as mentioned above, we also expect some consumer news, following both past-year trends and the magnitude of this event. The schedule includes a chat with Jony Ive, so it is very possible we get an update to the highly anticipated AI wearable OpenAI has been working on.
This is the company's biggest DevDay ever, with media invited for the first time and over 1,500 attendees. The event itself is taking place at Fort Mason in San Francisco.
Event day schedule
The day is going to kick off with a livestreamed keynote with Sam Altman at 10 a.m. PT. Then there will be chats with Greg Brockman, president of OpenAI; Brad Lightcap, OpenAI's chief operating officer; and Jony Ive, a former Apple designer working on OpenAI's hardware product.
