Transcript context
…I think part of it is also we need to invest more in training improvements to make AI continuously strong on areas like writing. I think it's also the technology's jagged-edged, like we mentioned. So sometimes when the models were good at writing, but not agentic, our thesis is: how do we make the models more agentic or call the right tools? Now that that's improved a bit, then it's, well, now it's these other areas actually become more of the rough edges. And so I think we're in one of those moments worth writing where we need to actually just focus and prioritize on training the models to be great at this area. And that is a very active area for us. So fun that you mentioned. Okay. I'm glad. I'm glad. And also it was going to be interesting once AI is so good, we're like, "I don't know who wrote that. " But to your point, sometimes we actually want to know that it's AI. That's really interesting. I never thought of it that way. The other interesting part of this is that there's that comedian who was joking that we're on a plane and the WiFi's down and we're just like, "What the hell? The WiFi's not working on this plane. This sucks. How dare you?" When you're in a tube in the sky flying like a bird. And how dare you complain that the WiFi doesn't work? Your point is there's so much advancement and so much power. We can't fix it all. We can't make it all work the best possible and so basically writing has been not the priority, and it feels like there's more investment happening there. Yeah. I think tone and character is a priority. I think it's this advancement of the technology is a work in progress and so we see a leap or an emergence of a jump in agentic behaviors. And so that is a new normal. And then these other capabilities needs to continue improving. And I think once we improve, let's say, writing and tone and character, we probably will say, how do we have Claude be even more proactive? Proactivity is an opportunity, and that's human nature. We want to make ourselves better. We want to make this technology better and I think we're applying it to AI, which is the right thing. We should be making it better.…
