EU AI Act enforcement phase begins

From August 2, the European Commission's AI Office and authorities designated by EU member states became responsible for implementing and enforcing the AI Act. The Act entered into force on August 1, 2024 and became generally applicable on August 2, 2026, subject to phased exceptions and transition periods.

The August 2026 phase followed earlier application dates for prohibited practices and AI-literacy duties in February 2025 and for governance rules and general-purpose-AI obligations in August 2025. Separate transition periods continue to apply to specified high-risk systems.

Article 50 transparency duties take effect

The new transparency rules require chatbots and other interactive AI systems to inform users that they are interacting with AI rather than a human. Deepfake images, video, and audio must be labelled, and AI-generated or altered content must carry machine-readable marks intended to make synthetic content easier to detect.

The Commission published guidelines and a voluntary Code of Practice to help providers and deployers operationalize these obligations.

AI Office gains enforcement powers over general-purpose AI models

The AI Office's enforcement powers over general-purpose AI models include requesting technical documentation, evaluating models, requiring corrective measures, and issuing fines for noncompliance. Euronews reported that the model rules require disclosures about model development and copyright-protected training content, together with information enabling downstream users to understand model capabilities.

California AI Transparency Act becomes operative

California Business and Professions Code Chapter 25 became operative on August 2, 2026. The statute covers providers of publicly accessible generative-AI systems with more than one million monthly visitors or users in California.

Covered providers must make a no-cost tool available to assess whether image, video, or audio content was created or altered by their systems and to output detected system-provenance data. Providers must also offer users an option for a clear manifest disclosure and embed a latent disclosure in covered AI-generated media when technically feasible and reasonable.

The law authorizes the California Attorney General, city attorneys, and county counsel to seek civil penalties of $5,000 per violation, with each day of noncompliance treated as a separate violation. Separate platform-hosting provisions become operative January 1, 2027, and capture-device provisions phase in beginning January 1, 2028.
