Anthropic has published a report on how AI is changing work inside the company, drawn from its own internal records. Since early 2025, junior staff have fallen from 21% to 14% of employees in technical departments, and from 27% to 9% of technical hires. Code commits per engineer reached roughly five times their level of six months earlier, and by August agent hours in employee-directed sessions were about six times employee work hours. Non-technical staff are coding too: their coding-focused agent sessions rose from 2 a month in August 2025 to 90 in May 2026. Yet Claude sessions sat idle about 80% of the time, waiting for a human.
Why it matters: entry-level jobs are where many economists expect AI to bite first, and this is unusually detailed data from a company that uses AI more heavily than most. The authors are clear about the limits. Anthropic is studying itself, staff chose whether to adopt agents, the company grew fast over the same period, and the link between heavier AI use and slower junior hiring is descriptive rather than causal. They also say the lessons may not generalise across the wider economy.
