“And WhatMD, it's another example of this idea of, you know, do the simple thing first. We had all these crazy ideas about, like, memory architectures, and, you know, there's so much literature about this. There's so many different external products about this, and we wanted to be inspired by all this stuff, but in the end, the thing we did is ship the simplest thing, which is, you know, it's a file that has some stuff, and it's auto-read into context, and there's now a few versions of this file.”

Cherny: AI prototyping informs engineering decisions faster than writing design docs
“Before I would write a big design doc, and I would think about a problem for a long time before I would build it sometimes for some set of problems, and now I'll just ask quad code to prototype, like, three versions of it, And I'll try the feature and see whic…”
Cherny: Foundation models will eventually subsume external memory and RAG architectures
“Everything is the model. Like that's the thing that wins in the end. And it just, as the model gets better, it's it subsumes everything else. So, you know, at some point the model will encode its own knowledge graph. It'll encode its own like KV story if you j…”
Cherny: Claude Code delivers up to 10x productivity gains for Anthropic engineers
“Anecdotally for me, it's probably two X my productivity. So I'm just like, I'm an engineer that codes all day, every day. For me, it's probably two X. Yeah. I think there's some engineers at Anthropic where It's probably 10 X their productivity”
