Live updates and analysis from the AI startup

OpenAI’s Christina Huang, a member of the company’s technical staff, built an AI agent within eight minutes to demo AgentKit to the audience.

The agent was completed with 49 seconds to spare and was live for attendees to use.

“So in just a few minutes, we’ve designed an agent workflow, visually,” Huang said. “We added in some tools and widgets. We previewed it, we deployed it, we tested it, and now you all can use it.”

Developers of apps will soon be able to easily plop in a ChatGPT-powered artificial intelligence chat into their apps or websites, Altman said. The product is called ChatKit.

“You get a simple, embeddable chat interface that you can make your own. You can bring your own brand, your own workflows, whatever makes your own product unique,” Altman said.

Altman introduced AgentKit, which is designed to help developers build AI agents and take them from “prototype to production,” he said.

“Our hope is that everyone from individual developers to large enterprises will get a lot of value from this,” Altman said.

OpenAI showed a live demo of App SDK, where a user asked ChatGPT to create poster mock-ups for a dog walking business using Canva.

After a couple of minutes, Canva generated four different posters for the business and presented them to the user right within the chatbot.

Users can also ask for follow-up edits and create other forms of media. OpenAI also generated a pitch deck as part of the demo.

Coursera stock popped over 6% as the company was used as a demonstration of deep integration with ChatGPT.

OpenAI demonstrated using ChatGPT to access a Coursera video inside ChatGPT, and demonstrated how the AI was able to go deeper on some topics in the video.

“Here, ChatGPT responded and explained the instructor’s data preparation steps before training a machine learning model, and then it breaks it down a couple times,” said Alexi Christakis, a software engineer.

Coursera was founded in 2012 to provide access to computer science courses. Its founders, Daphne Koller and Andrew Ng, are considered to be artificial intelligence luminaries.

Altman introduced App SDK, which will allow users to access apps directly through the company’s chatbot, ChatGPT. A user could type in ask the chatbot to create a playlist for a party, for instance, and get recommendations from Spotify.

Altman opened the session with a few stats — 800 million weekly users, 4 million developers, and 8 billion tokens processed per minute using the company’s API.

That user number is up from last month, when OpenAI said it hit 700 million weekly active users.

Over 22,000 people were streaming the announcements on YouTube as it kicked off.

Altman’s chat with the ex-Apple design chief Ive will be a highly anticipated part of this year’s event.

OpenAI rocked the tech sector in May when it announced it would buy Ive’s AI devices startup io for about $6.4 billion.

Ive is responsible for designing Apple’s most iconic products, including the iPod, iPhone, iPad and MacBook Air. He is now overseeing “deep creative and design responsibilities across OpenAI,” according to a blog post.

The company has kept its work with Ive under wraps, but a screen-less hardware device is reportedly in the works, according to several media outlets.

Early Monday, OpenAI announced a deal with Advanced Micro Devices that sent the chipmaker’s stock soaring more than 30%.

OpenAI will deploy 6 gigawatts of AMD’s Instinct graphics processing units over several years, the companies said. AMD has also issued OpenAI a warrant for up to 160 million shares of AMD common stock with vesting milestones tied to both deployment volume and AMD’s share price.

“We need as much computing power as we can possibly get,” OpenAI President Greg Brockman told CNBC in an interview on Monday.
