EU AI Act obligations

Risk tier: Not applicable · as of 2026-08-23

Source-backed information mapped from Braintrust's tracked risk tier — not legal advice. Obligations depend on how your organisation deploys the system; see the full obligation reference and timeline.

This record's EU AI Act risk tier is marked not applicable, so no tier-specific obligations attach. Deployers embedding it in an AI system in scope of the Act should assess that system's own tier.
