- Keep a professional in the loop: the Wft duty of care and GDPR set high requirements: financial and health data belong only in GDPR-compliant systems with a data processing agreement, and the advice remains the adviser's responsibility.

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
