Anthropic has published internal research examining how AI is transforming work among its own engineering team, according to a study posted on anthropic.com.
In August 2025, the company surveyed 132 engineers and researchers, conducted 53 qualitative interviews, and analyzed internal Claude Code usage data. According to anthropic.com, employees report using Claude in 60% of their work and achieving a 50% productivity boost—representing a 2-3x increase from the previous year.
The study found that debugging and code understanding are the most common uses of Claude among Anthropic’s technical staff. According to the research, 27% of Claude-assisted work consists of tasks that “wouldn’t have been done otherwise.”
The findings reveal both benefits and concerns. Engineers report becoming more “full-stack” (able to succeed at tasks beyond their normal expertise), accelerating learning and iteration speed, and tackling previously-neglected tasks. However, according to anthropic.com, some employees worry about potential trade-offs, including losing deeper technical competence, reduced ability to supervise Claude’s outputs, and decreased collaboration with colleagues.
Anthropic acknowledges that studying AI’s impact at an AI-building company represents “a privileged position,” but suggests these findings may serve as “an instructive harbinger of broader societal transformation.” The data was collected when Claude Sonnet 4 and Claude Opus 4 were the most capable models available.
