According to 9to5Google, Google issued company-wide AI coding guidance to its software engineers, detailing best practices for AI adoption in their work, following CEO Sundar Pichai’s April 2025 statement that over 30% of Google’s code is AI-generated.
The guidance, formally released today, was preceded by an email to all software engineers on Monday, providing recommendations and best practices for integrating AI into their workflows. This document was developed by Google engineers and incorporates successful AI integration strategies observed within the company. The overarching objective is to enhance individual engineer productivity and foster more rapid iteration and development cycles.
The guidance encompasses the application of AI assistance in coding, alongside an elucidation of the current capabilities and limitations of existing AI technologies. Google intends for its engineers to comprehend the methodologies for constructing AI-based systems. Specifically, technology leads and managers are expected to gain proficiency in integrating AI development into their respective teams.
The statistic indicating that over 30% of Google’s code is AI-generated signifies a process where AI produces code, which then undergoes human review and acceptance. This figure represents an increase of over 5% within a six-month period. Today’s comprehensive guidance places significant emphasis on “maintaining rigor” across critical development phases, including code review, security protocols, and ongoing maintenance.

Google is encouraging its employees to explore and leverage AI applications beyond the scope of coding activities. This current guidance marks the most formal communication from the company regarding AI utilization, building upon previous notable instances of AI adoption within Google. Pichai previously stated that the utilization of AI has resulted in an estimated 10% increase in engineering velocity, defined as the volume of software development work completed within a specific timeframe.
This internal development aligns with Google’s external product releases over the past year, which include Gemini Code Assist, Gemini CLI, and Gemini in Android Studio. Google confirmed the issuance of this AI guidance, stating, “Our engineering teams are already regularly using our AI tools for coding, fixing bugs, and much more. These recommendations and best practices, developed by a group of software engineers at Google, are designed to help all SWEs across the company get the most out of AI in their day-to-day work.”
