Questions asked in this interview

3
  1. 17:44When can we do a tasting?
  2. 39:50It failed the vast majority of times on a task that took a day or longer but as of July and August our models have taken on over a third of day-long research tasks with no intervention required. So what does this mean?
  3. 54:52Are you excited to be at Dev?
Sam Altman 14:08 ↗
Good morning. It is great to have everyone here and everyone joining us online. Thank you for coming. I think this is going to be our best day yet. We have shipped a lot and you have built amazing things with it. You find uses for those models that we have thought of. You've helped make our products better. You have sent us thousands of requests, mostly on Twitter, for ideas for ways we can improve. We try to work through them as fast as we can. You asked us to bring Codex to Linux, so we did that.
You asked us to work across multiple folders in one project, so now you can do that too. And you asked for Codex on your phone, so we brought it there. It gives us a lot of joy to build things that you find helpful. And the next thing is one of the things that you've asked for the most. It's something we have been excited about too, so let's get into it. We are kicking you off with a product that we believe is going to be a whole new way to work with AI. It's like a helper that always has your back. It can expand your potential, working 24/7 to take on the deluge you don't want to do so you can focus on higher-level work.
Now, you may have seen early signs of what this can look like in consumer assistants that help you book a reservation or buy a plane ticket. And these are helpful, but they are trivial to what the technology can do. So we want to be more ambitious. It knows what's going on. It knows what matters to you. You don't have to tell it every little thing to do. We want AI to feel like that. We want it to feel like magical things that it does without you having to ask. So today we're introducing Dots.
Dots are remarkably capable, always-on agents built to handle anything you can think of. They bring AI into a whole new form factor to work and give you more time and attention so you can do more things that you care about. Let's meet Dots.
Dot 16:52 ↗
Hey, I'm your Dot. I'm new in ChatGPT. I'll be here to handle everything that comes your way. Ready to jump in when you need me.
Sam Altman 17:01 ↗
I'm going to call you Alfred.
Dot 17:04 ↗
You got it. I'm Alfred.
Sam Altman 17:06 ↗
I'll keep things moving and check on things when you think it's important. The latest consumer experience numbers came in on time. I've been updating your board meeting deck. So I've cut your migration in Mar-a-Lago meet notes.
Dot 17:28 ↗
Get it started, but make sure you first check every flow against the current product before I review.
Sam Altman 17:35 ↗
Also, update on wedding planning. Bad news, the cake vendor canceled. Good news, I already found a backup.
Dot 17:44 ↗
When can we do a tasting?
Sam Altman 17:46 ↗
Saturday, whenever works for you.
Dot 17:52 ↗
Hey there. Your website's updated with the new designs for the forward drop. Check it out.
Sam Altman 18:02 ↗
Nice. I like that. Just walk the first and third photo and then you can publish the site. Dot, you're live.
Dot 18:10 ↗
Your board meeting deck is ready. Revenue is up 51 percent year over year.
Sam Altman 18:17 ↗
Okay, this looks good except for change it so the consumer experience is first and then get into the growth serial numbers. How's it looking?
Dot 18:24 ↗
Is it rebuilt? It's faster in testing with no regressions so far.
Sam Altman 18:31 ↗
Amazing. Share the team on Slack.
Dot 18:36 ↗
Also, the kids' after-school lessons as soon as registration opens.
Sam Altman 18:41 ↗
They'll love that. Thank you. I'm going to see if we can reschedule.
Dot 18:49 ↗
Okay, please. I can't miss that recital.
