Anthropic’s Chief Product Officer Mike Krieger has made a bold claim: Claude AI now writes nearly all the code at the company. Engineers ship pull requests with 2,000 to 3,000 lines fully generated by Claude.
This marks a full shift from manual coding to AI-driven development. It proves CEO Dario Amodei’s March 2025 prediction true—AI would handle 90% of code soon and almost all within a year. Many doubted it back then.
Today, it is the reality at Anthropic.
Claude Writes Code at Anthropic: From Skepticism to 100% AI Code
Dario Amodei forecasted big changes. He said AI would write 90% of code in 3-6 months and essentially all in 12 months. People called it crazy.
Now Krieger says for most products, it is effectively 100%. Engineers no longer write lines by hand. They craft prompts, review output, and focus on big ideas.
Boris Cherny, head of Claude Code, shared he has not touched code manually for over two months. He ships 20-30 pull requests daily, all 100% from Claude.
Internal data shows 50% higher productivity and 2-3x faster work. Claude Code now runs 20 independent actions per task, double from six months ago.

Changing Roles and Industry Impact
Engineers move to oversight and creative work. Cherny says he feels more joy since Claude takes the boring parts. This raises questions for software jobs worldwide.
At places like Microsoft, AI does about 30% of code. Indian IT firms like Infosys, TCS, and HCLTech saw stock dips after the news. Investors fear less need for traditional coding services.
Some point out humans still design prompts and check for bugs or security issues. The news shows top AI labs lead fast adoption. It hints at a future where AI builds most software with little human typing.

This milestone speeds up AI in real engineering. It changes how teams work at places like Anthropic in Mumbai and beyond.
Watch for more shifts as models improve.
