75% of Google's New Code is Being Written By Claude Code
Google CEO Sundar Pichai announced that 75% of all new code at the company is now AI-generated and approved by engineers, up from 50% last fall and over 30% a year ago.
Human engineers review, modify, and accept the output rather than writing from scratch, shifting roles toward orchestration in "agentic workflows".
A recent complex code migration finished six times faster using AI agents and engineers. This rapid adoption highlights AI's transformation of software development at Google, with humans as final gatekeepers.
