Claude Now Writes 80% of Anthropic's Code

Anthropic revealed that over 80% of code merged into its production codebase in May was written by its own AI model, Claude, not by humans. The shift has driven an 8x increase in code shipped per engineer per quarter compared to its 2021-2025 baseline. For enterprise leaders, this marks a new competitive benchmark. If a frontier AI lab can hand off the majority of its engineering output to autonomous agents, pressure mounts on businesses across all sectors to accelerate their own AI-driven development strategies.
