Past simple

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 two years since our first Dev Day.

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 ChatGPT users.

We are 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 OpenAI.

More than 800 people use ChatGPT 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 to 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.

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 what matters most to you all, which is making it easier to build with AI.

We've been listening to developers, hearing where you get stuck, what you want us to build next so that you can build more things.

Today, we're going to show you how we're making it possible to build apps inside of ChatGPT and how we can help you get a lot of distribution.

We're going to show you how building agents is going to be much faster and better.

You'll see how we're making it easier to write software, taking on the repetitive parts of coding so you can focus on systems and creativity.

And underneath all of this, we'll give you updates to models and APIs to support everything you want to build.

We think this is the best time in history to be a builder.

It has never been faster to go from idea to product.

You can really feel the acceleration at this point.

So to get started, let's take a look at apps inside of ChatGPT.

We want ChatGPT to be a great way for people to make progress, to be more productive, more inventive, to learn faster, to do whatever they're trying to do in their lives better.

We have been continuously amazed by the creative ways that people use it.

Since our first dev day, we've been working to try to figure out how to open up ChatGPT to developers.

And we've tried things like GPTs, we've adopted standards like MCPS, and

we've made it possible for developers to connect ChatGPT to more and more applications.

Some of this stuff has worked, some of it hasn't.

And today we're going to open up ChatGPT for developers to build real apps inside of ChatGPT.

This will enable a new generation of apps that are interactive, adaptive and personalized that you can chat with.

So to build them today we're launching the Apps SDK, which will be available in preview starting today.

With the Apps SDK, you get the full stack.

You can connect your data, trigger actions, render a fully interactive UI and more.

You get full control over your backend logic and front end ui.

We've published the standard so that anyone can integrate the app's SDK.

When you build with the apps SDK, your apps can reach hundreds of millions of ChatGPT users.

We hope this will be a big deal for helping developers rapidly scale products.

If a user is already subscribed to your existing product, they'll be able to log in right from the conversation.

And in the future, we're going to support many ways to monetize, including the new Agentic commerce protocol that offers instant checkout right inside of ChatGPT.

When someone's using ChatGPT, you'll be able to find an app by asking for it by name.

For example, you could sketch out a product flow for ChatGPT and then say figma.

The Figma app will take over, respond and complete the action.

You can Also then launch Figjam from ChatGPT if you want to iterate further.

We're also making apps discoverable right in the conversation, so when a user asks for something, we can surface a relevant app as a recommendation.

Maybe a user says they need a playlist for their party this weekend.

ChatGPT could then recommend building it in Spotify.

It's an easy way to find the right app or have the right app presented to you at the right time, and

there'll be a whole bunch of new ways for developers to get discovered.

So now, rather than just talk about this, I'd like to invite Alexei to the stage and we'll show you a live demo.

Hi, I'm Alexi, a software engineer on ChatGPT working on apps SDK.

I'm super excited to showcase some of the first apps users will be able to interact with today.

The magic of these apps is combining their rich interactive visuals with the power of ChatGPT.

Let's say I don't spend enough time thinking about machine learning at work and I want to learn more.

I can ask the Coursera app in ChatGPT to help me learn more about this.

I can say, coursera, can you teach me something about machine learning?

Since this is my first time using Coursera in ChatGPT, I'll need to consent to connect the next time I use it, I'll be able to dive in immediately.

You'll notice I asked ChatGPT for the Coursera app directly, but

ChatGPT can also suggest apps if relevant to the conversation.

Apps in ChatGPT by default are displayed in lang and can support anything that you can render on the web, like this video shown here.

Apps SDK also supports picture in picture or expanding to a full screen layout.

So now that I have my course up, let's play the video.

Playing the video immediately pins it to the top of my screen, which is really helpful for something like Coursera because you can access your conversation while watching the video.

Let's skip ahead a little bit and say I want to go a little bit deeper on something mentioned in the video.

I can ask ChatGPT, can you explain more about what they're saying right now?

Apps SDK provides an API to expose Context back to ChatGPT from your app, ensuring that the model always knows about exactly what your user is interacting with.

We're calling it Talking to Apps and it's really part of the magic here.

I'm super excited about how learning with ChatGPT, one of our top use cases, is continuing to get better.

And with Apps and the Apps SDK, you can unlock richer educational experiences for users around the world.

So here ChatGPT responded and explained that the instructor is talking about data preparation steps or before training a machine learning model.

And then it breaks it down in simple terms for me.

I don't need to explain what I'm seeing in the video.

So here I was able to connect Coursera's app, discover it's our playing a course and directly engage with the video through text.

All within my existing ChatGPT conversation.

Users also love being creative in ChatGPT.

Here I have a conversation where I've been brainstorming some ideas to help my younger siblings dog walking business.

We've gone back and forth a few times and now it's time to make this into a reality.

I'm pretty happy with some of the names here, so let's take this walk this wag name.

And now I'm going to ask Canva to turn that into a poster.

I can say canva, can you make me a poster with the Walk this wag name?

I want it to be colorful, whimsical, write and I prefer, oops, ask Coursera for a typing course too.
