ChatGPT starts exposing writers using AI with invisible watermarks; OpenAI says its texts, codes can be traced; how to avoid detection

OpenAI is rolling out invisible text watermarking for eligible ChatGPT and Codex output in the European Union, allowing its detector to look for a statistical signal hidden in the model's word choices. The technology can identify many longer passages, but OpenAI says editing, translation, short text and technical subjects can weaken detection. The system also cannot establish who wrote a passage, how much a human contributed or whether the content is accurate.
