On August 2, 2026, three things happen simultaneously: Article 50 transparency obligations become enforceable, the AI Office gains full enforcement powers over GPAI providers, and notification rules for high-risk AI apply. This is the second major enforcement milestone after the February 2, 2025 prohibition date.
EU AI Act August 2 Deadline: Final Countdown — Everything That Must Be Ready
What happens on August 2, 2026
This is the EU AI Act's second enforcement milestone — and the one that affects the largest number of organisations. While February 2, 2025 prohibited a narrow set of AI practices, August 2, 2026 activates obligations that touch any company using AI to interact with customers or generate content.
Obligation 1: Transparency (Article 50)
All four categories of Article 50 transparency become enforceable:
| Category | What must happen |
|---|---|
| AI-human interaction | Users must be informed they are interacting with AI |
| Synthetic content | AI-generated content must be marked with machine-readable metadata |
| Emotion recognition / biometrics | Affected individuals must be notified before the system is used |
| Deepfakes | AI-generated or manipulated media must be disclosed |
Obligation 2: GPAI enforcement
The European AI Office gains full enforcement authority over general-purpose AI model providers. GPAI obligations have been in force since August 2, 2025 — providers have had one year to comply. Now the AI Office can investigate, request information, and impose penalties.
Obligation 3: High-risk AI notification
Notification rules for bodies conducting conformity assessments of high-risk AI systems take effect. While the full high-risk compliance deadline was postponed to December 2027, the infrastructure for assessment begins now.
What is NOT due on August 2
Equally important — these obligations are not yet enforceable:
- Annex III high-risk AI requirements: Postponed to December 2, 2027 (revised by Digital Omnibus, May 2026)
- Annex I high-risk AI requirements: Due August 2, 2028 (AI in regulated products)
- Full conformity assessment: Not required until the relevant high-risk deadline
Do not let confusion between these dates cause either panic (thinking everything is due now) or complacency (thinking nothing is due yet).

- Designated contact for AI Office or national authority inquiries
- Ongoing monitoring process established (quarterly minimum)
Penalty exposure summary
| Violation | Maximum penalty | Status |
