OSS projects banning AI-generated contributions

At least 22 open-source software projects have adopted policies explicitly banning AI-generated contributions, including code, documentation, and issue comments. Major projects like Immich, Meilisearch, OkHttp, and Servo are rejecting pull requests created with tools such as GitHub Copilot, ChatGPT, and Claude, citing concerns about quality and authenticity. The trend reflects growing resistance within the open-source community to AI-assisted development.
