EU AI Act Enforcement and New Transparency Rules Begin 2 August 2026
From 2 August 2026, the EU AI Office and national authorities begin enforcing the AI Act, including new rules requiring AI systems to disclose AI interaction and label AI-generated or altered content.
What's Changing
Starting 2 August 2026, the European Commission's AI Office, working alongside national authorities, will begin enforcing the Artificial Intelligence (AI) Act. Alongside enforcement, new transparency requirements take effect on the same date, obliging certain AI systems to disclose when a user is interacting with AI rather than a human, and to flag when content has been generated or altered by AI.
Specifically, chatbots and other interactive AI systems must inform users they are dealing with AI, not a human. Deepfakes—AI-edited or AI-generated images, videos, or audio—must be labelled. AI-generated or altered content will also need to carry machine-readable marks to make it more easily detectable.
Purpose and Industry Response
According to the Commission, these measures are designed to reduce deception and manipulation and to help people make informed choices when engaging with AI-driven content or systems. At the same time, the rules are intended to give businesses clearer obligations and a practical route to demonstrate compliance.
As part of this rollout, the Commission published a first list of more than 180 organisations that have signed the Code of Practice on transparency of AI-generated content, which operationalises the new transparency obligations. Additional resources referenced include an AI Act complaints tool, an AI Act Whistleblower Tool, a complaints channel for downstream providers using general-purpose AI models, Guidelines on Transparency of AI-generated Content, the General-Purpose AI (GPAI) Code of Practice, Guidelines for providers of GPAI models, and Guidelines on prohibited AI practices.
What This Means
Organizations deploying chatbots, interactive AI systems, or tools that generate or alter images, video, audio, or text should confirm that user-facing disclosures and machine-readable marking mechanisms are in place ahead of the 2 August 2026 enforcement date. Providers of general-purpose AI models, and downstream providers relying on them, should review the available complaints channels and guidance documents to understand how enforcement will apply to their role in the AI value chain. Signing or benchmarking against the Code of Practice on transparency of AI-generated content may offer a practical way to demonstrate compliance, given that over 180 organisations have already done so. Compliance, legal, and engineering teams should treat this date as a concrete deadline for operationalizing transparency features rather than a future planning item.
