## Recent evidence

- [confirms] OpenAI will watermark ChatGPT and Codex text in the European Union to comply with the AI Act (2026-10-07): OpenAI's EU-only textGrain watermark is detectable only with the provider's own statistics, and it degrades to about 66% detection under light synonym swaps. Detection power sits with the model vendor, while the mark proves little about where any given text came from.
