Google: AI Now Writes 75% of Its New Code

At Google Cloud Next 2026, CEO Sundar Pichai confirmed that 75% of all new code written at Google is now AI-generated and reviewed by engineers — a sharp jump from ~50% last fall and just 25% in October 2024.

The pace of adoption is striking. Google isn't just using AI for boilerplate — Pichai cited a recent internal code migration completed 6× faster than normal, powered by agentic AI workflows. Engineers still approve the output, but the ratio of human-to-machine authorship has fundamentally flipped.

This isn't a moonshot stat anymore — it's an operational baseline at one of the world's largest engineering orgs.

Why it matters: when the company that built software engineering at scale says AI writes most of its code, the rest of the industry isn't far behind.
