AI writes most Google code
- Business Insider reports Google now generates about three quarters of its new code with AI assistance. - The specific figure cited is 75% of the company's new code being AI-generated. - That shifts engineer value toward architecture, review quality, testing and safe deployment of generated code (businessinsider.com).
Google says artificial intelligence now generates 75% of its new code, with human engineers still reviewing and approving what gets shipped. (blog.google) Chief executive Sundar Pichai disclosed the figure in a Google Cloud Next post published April 22, 2026. He said the share was 50% last fall, marking a sharp jump in a matter of months. (blog.google) Google has been moving toward that number in public steps. Pichai said on Alphabet’s October 29, 2024 earnings call that more than a quarter of Google’s new code was being generated by AI and then reviewed and accepted by engineers. (abc.xyz) By April 24, 2025, Pichai was telling investors that AI was powering new features across Google’s business, as the company tied more of its growth story to AI infrastructure, models and products. Google Cloud Next 2025 also centered its developer pitch on Gemini tools and multi-agent systems for software work. (abc.xyz) (cloud.google.com) The change inside Google is not just autocomplete for programmers. Pichai said the company is shifting to “agentic workflows,” meaning engineers assign larger chunks of work to software agents instead of accepting one suggestion at a time. (blog.google) Pichai said one recent code migration was completed six times faster by agents and engineers working together than engineers alone could do a year earlier. That points the bottleneck away from typing code and toward checking, testing and deploying it safely. (blog.google) Business Insider reported Google has also been pushing employees to use AI tools more broadly, with some AI goals factored into performance reviews this year. The outlet also reported some Google DeepMind employees were allowed to use Anthropic’s Claude Code in recent months. (businessinsider.com) Google is not alone in pushing AI deeper into software work. Business Insider reported that Microsoft chief executive Satya Nadella said in April 2025 that 20% to 30% of code for some Microsoft projects was written by AI, while Meta set internal targets for more “agent-assisted” code changes. (businessinsider.com) At Google, the headline number still comes with a human backstop. The company’s own phrasing is that AI-generated code is “approved by engineers,” which leaves the final responsibility with the people reviewing what the machines produce. (blog.google)
