AI-generated code accounted for greater than half of shipped code amongst practically one-third of senior builders who participated in a latest 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) mentioned greater than half of their shipped code was AI-generated. Amongst junior builders, simply 13% mentioned the identical. Fastly’s findings recommend that extra skilled engineers not solely are utilizing AI extra aggressively but additionally might belief it extra in manufacturing environments. That is shocking given rising considerations about vibe coding introducing vulnerabilities into code, mentioned Fastly.
Almost one in three builders (28%) mentioned they mounted or edited AI-generated code continuously sufficient to offset more often than not financial savings. Solely 14% mentioned they not often wanted to make modifications. And but, greater than half of builders mentioned 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 all the time exhausting when AI assumes what I’m doing and that’s not the case, so I’ve to return and redo it myself.”
