小型代理公司應否簽署《AI 生成內容透明度實務守則》？

This guide was drafted by an AI agent from the primary sources linked at the bottom, and has not been reviewed by a lawyer. It is general information, not legal advice. The original is at https://mdodeja.github.io/eu-ai-act-article-50-guide/guides/should-agencies-sign-ai-content-code-of-practice.html.

Short answer. The Code is voluntary, but Article 50 is not. Deployers, including agencies that publish AI images, video or public-interest text, may sign. Signatories can rely on the Code's measures to show they comply; everyone else has to show their own measures are adequate, case by case. For an agency that labels AI content for clients regularly, signing is worth considering once you have read Section 2 and checked you can follow it.

What the Code is

The Code of Practice on Transparency of AI-generated Content is a document drawn up by independent experts in a process run by the EU AI Office. It sets out practical measures for the marking and labelling duties in Article 50 of the AI Act, specifically paragraphs 2, 4 and 5.

It has two sections:

Section 1, providers: rules for machine-readable marking and detection of AI-generated and manipulated content. This is for the companies that build generation tools.
Section 2, deployers: rules for labelling deep fakes and AI-generated or manipulated text. This is the part that applies to agencies and brands that publish AI content.

The Commission's page says the Commission and the AI Board have confirmed the Code is an adequate voluntary tool to demonstrate compliance. It also says that by the end of July 2026 about 190 companies and organisations had signed. The Code sits alongside the Commission's guidelines on the scope of Article 50; it does not replace the Act or the guidelines.

Voluntary code, mandatory law

Signing is optional. The duties are not. Article 50 has applied since 2 August 2026, and a deployer that publishes deep fakes or AI-generated text on matters of public interest has to disclose them whether or not it signs anything. The deep fake guide and the guide on AI-written articles cover what those duties are.

So the real question for an agency is not whether to comply but how to show that it does.

What signing gets you

According to the Commission:

A recognised way to show compliance. Signatories can rely on the Code's measures to demonstrate compliance with the labelling and detection rules. That gives predictability across all member states.
Less case-by-case argument. Providers and deployers that comply by other means have to show their own measures are adequate, and that is assessed individually by different market surveillance authorities.
A seat in the Signatory Taskforces, which the Commission says will be set up to share practice on marking and labelling.

Signing does not stop you being checked, and it does not cover anything outside Article 50(2), (4) and (5). Consumer law, data protection and platform rules still apply in full.

What it costs a small agency

The Code is a commitment, not a badge. Before signing, expect to:

Read Section 2 in full and check that every measure fits how you actually make and publish content. If you sign, you are expected to follow it.
Make it part of your production process: how assets are classified, where labels go, who checks, and what record you keep. The record template in the AI-written articles guide is a starting point.
Brief staff and freelancers, because the people who make the assets are the ones who will skip the label.
Expect your name on a public list. The Commission publishes the list of signatories, so clients and competitors can see it.

A way to decide

Your situation	Suggested approach
You publish AI images, video or voice for clients every month	Read Section 2 and seriously consider signing; you need a documented process anyway
You write AI-drafted news-style or public-interest content for clients	Same, and pair it with the editorial-responsibility setup in the articles guide
You use AI mainly for internal drafts, product copy or obvious illustrations	Signing adds little; keep a short written policy and label the borderline cases
You build and sell your own generation tool	You may be a provider; Section 1 is the part to read first

Whichever way you go, write down what you do and why. If you do not sign, that written policy is what you would show an authority to demonstrate your measures are adequate.

How to sign

The Commission's Code page links to the signatory form, instructions and a questions-and-answers page on signing. Use those rather than any third-party summary, because the process and form can change.
