Anthropic’s IPO filing shows how AI is changing the job of a software engineer

Anthropic's IPO filing reveals that its AI model Claude wrote more than 90% of contributions to the company's codebase in September. The Claude maker said its engineers increasingly direct and review AI output, with daily code contributions per engineer rising over 45 times from 2024 levels. Anthropic's workforce grew from about 940 to 5,300 employees, and the company is betting on a low-ego culture.
