Claude writes about 90% of Claude Code's code

OpenAI’s Claude model reportedly generates the majority of the code for its own codebase, with about 90% of the code written by the model itself. The claim highlights the model’s self‑coding capabilities and raises questions about code quality, maintenance, and the role of human developers. The story was shared on Hacker News. This development could influence future software engineering practices.
