“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
