4 November 2026Watermark in Grok API text from 7 November (AI Act)

From 7 November 2026, responses from grok-4.7, grok-4.6, grok-4.5, grok-4.3 and the grok-4.20 variants via the API will carry an invisible statistical watermark, to comply with the EU AI Act. The mark sits in the word choice and survives copying and pasting; the x-watermark header indicates whether a response is marked. A team administrator can switch it off per model, but must then confirm that a legal exemption applies. The detector is available on request only. source

What should I look out for with AI in the pharmaceutical industry?
This sector involves health data of trial participants and patients (special category personal data under Article 9 GDPR) and confidential research data. Ask every provider where the data is stored and whether it is used to train models: Castor hosts in the Netherlands (Google Cloud europe-west4) and does not share data or models between customers, Cradle states that source data never goes to third-party AI models, Iris.ai hosts on AWS in Ireland and Germany. Biolevate and Ennov also run in private cloud or on-premises. With Veeva Vault AI and Yseop, texts go to Anthropic models via Amazon Bedrock; check the region and the data processing agreement. If you work in GxP processes, an AI tool must also be validated (EU GMP Annex 11) and a competent employee remains responsible. For AI in medicines development, the EMA has a reflection paper (2024) and is working with the FDA on joint principles.
