Generative AI Rewrites Chardet Allowing Relicensing
On April 3, 2026, maintainer Dan Blanchard released chardet 7.0, a ground-up rewrite produced with Anthropic's Claude Code and relicensed from LGPL to the permissive MIT license. Blanchard says he used an "AI clean room" process—starting an empty repository and instructing the model not to base output on LGPL/GPL code. The change highlights how generative-code tooling can enable relicensing and complicate GPL enforcement for open-source projects.
