OpenAI watermarks ChatGPT text only in the EU; will Anthropic follow suit?

vb100 · reddit · 2026-10-08

A Reddit post highlights OpenAI's Monday announcement that invisible text watermarking will roll out in the coming weeks for eligible ChatGPT and Codex output — across all plans, but only in the EU, with no global default at launch. Anthropic previously said it would apply Claude text watermarking globally because it lacked "a durable way to scope it by region," an excuse that looks weak now that a direct competitor solved regional scoping. The author asks how long before Anthropic follows suit.
