“So coding is solved for the kind of coding that I do. It's not solved for everyone. You know, there's still code bases that are like super deep systems code bases where quad still struggles. There's distributed systems where quad still struggles. There's really kind of in the weeds UI verification, like something is off by pixel or something, but it's still not perfect at this. Like Opus five was a big leap in vision and computer use, but it's still not perfect.”

Cherny: Bun codebase was rewritten to Rust in 11 days using Claude
“And he had the model rewrite it from Zig to Rust. It was one prompt. It was a dynamic workflow, and a dynamic workflows are a feature in quad code that essentially let you orchestrate, you know, dozens, 100,000 of agents to do work productively. And it ran for…”

Cherny uninstalled his IDE and lands 20 AI-written PRs daily
“For me personally, it's been a hundred percent for like since Opus 4.5. I just, I uninstalled my IDE. I don't edit a single line of code by hand. It's just a hundred percent quad code in Opus. And you know, I land, you know, like 20 pairs a day, every day.”
