Long-term retention is the metric OpenAI prioritizes above all others for ChatGPT, because it signals that the product durably solves people's problems, and revenue follows from that rather than needing to be optimized directly.

3:33look at, um, all kinds of stuff in aggregate because really there isn't like this one single thing that you can optimize for. >> If you were to allocate a 100 units of points >> to these metrics, which metric can you like distribute the 100 units across these metrics in order of importance for you right this second? It's a good question. I I care a lot about long-term

3:51retention and I would put all my points there. Um because um I'm really proud of the retention stats we have. >> Huge, >> but ultimately the sign of durable values, whether or not people are coming back in three months because that means you're really solving their problems. And >> yeah, >> I think things like revenue, they follow from that. Um >> yeah. >> Um versus like, you know, trying to go

And um why why do you think like if you were to give us a narrative on that smile curve? What is the why do these smile curves exist? What are you seeing in

5:09Chad GPD that has people who have who have maybe turned off for a couple of weeks or months coming back and why are they coming back? >> Look, there isn't one single thing.
