AI-generated code accounted for greater than half of shipped code amongst almost one-third of senior builders who participated in a current survey by cloud platform supplier Fastly.
The corporate’s July 2025 survey of 791 skilled builders discovered that 32% of senior builders (these with 10 or extra years of expertise) stated greater than half of their shipped code was AI-generated. Amongst junior builders, simply 13% stated the identical. Fastly’s findings recommend that extra skilled engineers not solely are utilizing AI extra aggressively but in addition could belief it extra in manufacturing environments. That is shocking given rising issues about vibe coding introducing vulnerabilities into code, stated Fastly.
Practically one in three builders (28%) stated they fastened or edited AI-generated code often sufficient to offset more often than not financial savings. Solely 14% stated they hardly ever wanted to make adjustments. And but, greater than half of builders stated they felt they labored quicker with AI instruments like Copilot, Gemini, or Claude. “AI will bench-test code and discover errors a lot quicker than a human, repairing them seamlessly. This has been the case many instances,” one senior developer wrote. A junior respondent cited trade-offs: “It’s at all times laborious when AI assumes what I’m doing and that’s not the case, so I’ve to return and redo it myself.”
