Google has announced that three-quarters (75%) of the new code created within the company is now generated by artificial intelligence (AI) and subsequently reviewed by human engineers. This figure represents a rapid increase, growing from approximately 25% in October 2024 to 50% by Fall 2025, and now reaching 75%.
The company has been actively encouraging its employees to leverage AI for both coding and various other tasks. Google CEO Sundar Pichai stated in a recent blog post that Google is transitioning towards "truly agentic workflows," empowering engineers with more autonomous operations. Pichai highlighted a significant achievement: "Recently, a particularly complex code migration done by agents and engineers working together was completed six times faster than was possible a year ago with engineers alone."
Google engineers are primarily utilizing the company's Gemini models for code generation. This year, specific AI adoption goals will be integrated into employee performance reviews. Interestingly, some Google DeepMind employees have reportedly been permitted to use Anthropic's Claude Code in recent months, a decision that has generated internal discussion.
Google's reliance on AI for coding reflects a broader industry trend. Other tech giants, including Microsoft, are also significantly increasing their use of AI in software development, signaling a transformative shift in how code is created across the tech sector.
