Insane: 90-95% of Claude Code is now written by Claude Code. I asked Mike Krieger (Anthropic's CPO) what changes when so much of your code is written by AI? His answer: The bottleneck moves from coding/design to: 1. Upstream: aligning the team around what to build. 2. Downstream: the PR merge queue, reviewing and merging all of the new code into production. Anthropic is where other product teams will be in a year or two, so it's important we pay attention. "I would expect that a year from now, the way that we are conceiving of building and shipping software changes a lot. Because it's gonna be very painful to do it the current way."

Dario Amodei says the spark was seeing engineers stop writing code and start supervising it. Inside Anthropic, Claude writes much of the software, and humans review like editors. The twist is meta: some of that code helps build the next Claude. That’s the self-improvement loop tightening, says Dario Amodei.

📁 Boris Cherny, engineer at Anthropic, says 100% of his code is written by Claude. He ships 10 to 30 pull requests a day and has not edited a single line by hand in months. Claude writes it. Claude reviews it. Humans are still in the loop, but they are no longer the ones typing.

Boris Cherny, the creator of Claude Code at Anthropic, just explained why most people aren't getting real results from Claude in this talk he breaks down exactly how most people skipped the setup entirely: - 90% of code at Anthropic is written by Claude itself - the 14% you lose to CLAUDE.md before typing a word - lawyers, designers, and finance people are building real things with it - no CS degree. no background. nothing Boris Cherny: "Claude Code is 100% written by Claude Code, Cowork is 100% written by Claude Code" if you've been using Claude for months and never configured a single thing, you skipped the 20 steps that change everything. probably 25 instead of another show tonight, watch this make sure to bookmark it before it gets lost in your feed my breakdown of all 25 features is below

Creator and head of Claude Code, Anthropic: "I don't prompt Claude anymore. I have loops running that prompt Claude and decide what to do. My job is to write loops." He hasn't hand-written a line of code since November. 100% is Claude Code now. Still ships 10 to 30 pull requests a day. He breaks down his actual workflow in the 1h28m podcast. Loops writing 100% of the code. Engineer leveling up, or automated out?

""70, 80, 90% of the code written in Anthropic is written by Claude. (...) "I said something like this 3 or 6 months ago, people think of it as falsified because they think of it as like we're going to fire 70 80 or 90% of the software engineers but what really happens is that the 10% were still writing, you know, humans become managers of AI systems."

The first room of my 100% AI-developed ARPG is taking shape. → every model generated by meshy → every line of code written by claude code → Godot engine + MCP Now working on souls-like combat: 3-hit combos, dodge rolls, stamina, hitstop. It's a lot of fun.

Claude now writes 90 % of Anthropic’s code. Dario Amodei says that doesn’t cut jobs — it boosts output, as engineers handle the toughest 10 %. When AI hits 95–99 % automation, he expects major labor disruption within 2–5 years.
