October 6, 2026OpenAI's EU text watermark: Azure OpenAI is not covered yet
OpenAI's textGrain text watermark launched on 5 October 2026 in three states: on by default for ChatGPT and Codex in the EU, opt-in and off by default in the API, and not yet available through cloud partners such as Azure. Microsoft Foundry's provenance page lists only Claude models for text marking, so Azure OpenAI teams still own the Article 50(2) duty themselves, with the 2 December 2026 transitional deadline eight weeks away.
