Google CEO says 75% of company's new code is AI-generated

Google CEO Sundar Pichai said in a Wednesday blog post that three-quarters of the company's new code is now AI-generated and approved by engineers, up from 50% last fall. "We have been using AI to generate code internally at Google for a while," Pichai said. "Today, 75% of all new code at Google is now AI-generated and approved by engineers, up from 50% last fall." He added that Google is "now shifting to truly agentic workflows," with engineers "orchestrating fully autonomous digital task forces, firing off agents and accomplishing incredible things." Pichai wrote that Google is "staying on the cutting edge" by being "customer zero" of its own products. He said a recent "complex code migration" completed by both agents and engineers was done six times faster than what was possible just a year ago with engineers alone. Google Cloud senior director Richard Seroter told Fast Company that with AI-generated code approved by humans, engineers are able to focus on "higher-value tasks like system architecture, design and solving complex problems." Seroter said software engineers are becoming "product engineers, or architects, as they move away from manual coding and toward an agentic operating model." It is not just engineers utilizing AI tools at Google. According to Pichai's blog post, Google's marketing teams used AI models to "rapidly generate thousands of variations" of creative assets, which otherwise would have taken weeks. "Using AI led to 70% faster turnaround and a 20% increase in conversions, getting us to market faster and more effectively," Pichai said. At its Cloud Next 2026 conference, Google announced two new AI chips and a new Gemini Enterprise Agent Platform. Pichai also said Google will invest up to $185 billion on infrastructure to power autonomous AI agents.
