OpenAI

OpenAI is an American artificial intelligence research organization comprising both a non-profit foundation and a controlled for-profit public benefit corporation (PBC), headquartered in San Francisco, California. It aims to develop "safe and beneficial" artificial general intelligence (AGI), which it defines as "highly autonomous systems that outperform humans at most economically valuable work". OpenAI is widely recognized for its development of the GPT family of large language models, the DALL-E series of text-to-image models, and a text-to-video model named Sora, which have influenced industry research and commercial applications. Its release of ChatGPT in November 2022 has been credited with catalyzing widespread interest in generative AI. The organization was founded in 2015 in Delaware but evolved a complex corporate structure. As of October 2025, following restructuring approved by California and Delaware regulators, the non-profit OpenAI Foundation holds 26% of the for-profit OpenAI Group PBC, with Microsoft holding 27% and employees/other investors holding 47%. Under its governance arrangements, the OpenAI Foundation holds the authority to appoint the board of the for-profit OpenAI Group PBC, a mechanism designed to align the entity’s strategic direction with the Foundation’s charter. Microsoft previously invested over $13 billion into OpenAI, and provides Azure cloud computing resources. In October 2025, OpenAI conducted a $6.6 billion share sale that valued the company at $500 billion. In 2023 and 2024, OpenAI faced multiple lawsuits for alleged copyright infringement against authors and media companies whose work was used to train some of OpenAI's products. In November 2023, OpenAI's board removed Sam Altman as CEO, citing a lack of confidence in him, but reinstated him five days later following a reconstruction of the board. Throughout 2024, roughly half of then-employed AI safety researchers left OpenAI, citing the company's prominent role in an industry-wide problem.

Thanks for being here in San Francisco, the city where we started and where we are committed to building the future of AI. It's been almost 2 years since our first Devday. We, but most importantly, all of you have come a long way since then. Back in 2023, we had 2 million weekly developers and 100 million weekly Chacht users. We were processing about 300 million tokens per minute on our API and that felt like a lot to us at least at the time. Today 4 million developers have built with open AI. More than 800 people use chatbt every week and we process over 6 billion tokens per minute on the API. Thanks to all of you, AI has gone from something people build play [...] with to something people build with every day. Before we get started with all of today's announcements, we want to do something fun. On the screen behind me are the names of the developers in the room who have built apps on our platforms that have crossed some big milestones. 10 billion tokens processed, 100 billion, even 1 trillion. Let's give them a round of applause. [Applause] On behalf of all of us at OpenAI, thank you for doing such incredible work. You are the ones pushing the future forward and seeing what you've already done makes us so excited about what comes next. While it's exciting to celebrate how far you all have come, we are still so early on this journey. So today, we're going to focus on

First up, in terms of one of their product announcements was apps within Chat GPT. So, what apps within Chat GPT is is effectively a way that you can access different sites as well as their functionality directly within Chat GBT. Say for instance, if you want to connect to something like Spotify and make something like a playlist. So chatbd can do really well at creating things like playlist, but this takes it a step further where it will actually go and create a functional playlist on Spotify. You can use this for something like say Zillow and find different information about different homes in various cities. And there's a ton of different use cases for this whether it's using Canva [...] 13 comments ### Transcript:
