Google said that currently about 75% of new code within the company is generated by artificial intelligence and then reviewed by human engineers. This ratio has continued to rise in recent years, reflecting that Google is accelerating the deployment of generative AI tools in software development.

According to data previously disclosed by Google, as of October 2024, about a quarter of the company's new code will be generated by AI; last fall, this number had increased to 50%. Now it has increased to 75%, reflecting the significant increase in the weight of AI in Google's engineering system in just over a year.
Google has been pushing employees to use AI tools more broadly for coding and other office tasks. CEO Sundar Pichai said in a blog post on Wednesday that the company is transitioning to "truly agentic workflows" that will allow engineers to complete more tasks with the help of more autonomous AI agents.
For example, Pichai said that a recent particularly complex code migration was completed by an AI agent and engineers, and the overall time was shortened by six times compared with a year ago when it was completed by engineers alone. Such cases are regarded by Google as a direct reflection of the potential of AI agents in software engineering efficiency.
Currently, Google engineers mainly use the company's own Gemini model to generate code. Some employees have also been given specific AI usage goals, which will be factored into performance reviews this year to drive further adoption of the tools internally.
It is worth noting that some Google DeepMind employees were recently allowed to try out Claude Code launched by competitor Anthropic. This arrangement also caused a certain degree of tension and disagreement internally. Previous reports pointed out that the choice between different tool camps has caused some discussion and friction within the team.
Google isn't the only tech giant to make a big push into AI coding. Microsoft CEO Satya Nadella said in April last year that 20% to 30% of the code in some of the company's projects was already written by AI. Microsoft Chief Technology Officer Kevin Scott predicted in the same month that in the next five years, 95% of code will be generated by AI.
Social media companies are following a similar trend. The report quoted an internal document as saying that as of the fourth quarter of 2025, Meta has set a goal for software engineers in some organizations: 55% of code changes should be "Agent-Assisted." For the first half of 2026, 65% of engineers in the company's creation-related organizations will be required to use AI to write more than 75% of submitted code, according to the document.
Snap also said earlier this month that under its new operating model, at least 65% of the company’s new code will be generated by AI. As large technology companies such as Google, Microsoft, Meta, and Snap continue to increase their use of AI coding tools, AI is rapidly evolving from an "auxiliary tool" to an indispensable infrastructure in the software development process.
