OpenAI plans invisible watermarks for eligible ChatGPT and Codex text in the EU
OpenAI says API customers worldwide can opt in for select models, while watermarking remains off by default.
TLDR
On October 5, 2026, OpenAI said it would add invisible watermarks to eligible ChatGPT and Codex text output in the EU over the following weeks. API customers worldwide could opt in for select models starting that day. OpenAI says detector access will initially be limited to approved researchers and expert organizations because detection can miss watermarks or produce false positives.
