“What happened with Claude is now many companies, including Anthropic, and all of our biggest customers are reporting gains on the order of hundreds of percentage points. And I think the last number that we reported is the amount of code written per engineer at Anthropic has grown something like 250% since we introduced Claude code. And this is with, while keeping code quality and reliability and all of these things kind of stable.”

“Essentially we found both in the laboratory setting, and now we're finding in the wild, this is safer than what we had before. So as a user, it's a really nice benefit, because you don't have to sit there and say yes over and over, and actually the result is b…”
Cherny Stopped Writing Code Entirely, Using Claude to Prompt Other Claudes
“When you look at the kind of engineering that I do, I don't write code. I prompt quad. And actually nowadays, mostly what I'm doing is I have a Claude that prompts other Claude. So I don't even talk to Claude. I have a Claude that's talking to my Claude.”
Cherny: AI Agents Will Destroy Switching Costs as a Software Moat
