Article 50(2) is the provider duty: generative systems that produce audio, image, video or text must mark that output so it is machine-readable as synthetic or manipulated. The Commission's FAQ (digital-strategy.ec.europa.eu/en/faqs/transparency-obligations-under-article-50-ai-act) is the primary source. Systems already on the market before 2 August 2026 have a grace period to 2 December 2026. Watermark-detection interoperability runs to 2 February 2027. Fines can reach €15 million or 3% of worldwide turnover.
The mark is for a detector, a platform, or a downstream verifier. SynthID, other invisible watermarks, and C2PA-style manifests are the class of answers. A visible 'AI' badge in the corner is the deployer's kind of object, aimed at a person. A studio that hosts other people's models is a provider of the systems it puts on the market under its name; a creator who only prompts those systems is not.
Creators still care because the export they download either carries the mark or it does not, and they cannot add a robust machine-readable watermark after the fact. What they can add is the perceivable label. Confusing the two roles is how a team builds a watermarking pipeline they were never asked for, or assumes a tool's embedded signal means they can skip the on-screen line.
In practice
- If you did not place the generator on the market, you are not the addressee of 50(2).
- Keep the original export if you need the provider's mark intact; a social re-encode may strip a manifest.
- The on-screen label is still your problem as deployer when the clip is a deepfake going to an EU audience.
The mistake to avoid
Calling every vendor a provider under the Act. If you only prompted a hosted generator, you are the deployer; the machine-readable mark is not your duty.

Provider or deployer: who labels under Article 50
Providers mark output in machine-readable form; deployers label deepfakes visibly on first exposure. Here is which role you occupy on a hosted generator.

Deployer
A deployer, under the EU AI Act, is whoever uses an AI system under their authority. If you publish a deepfake, you owe the label the viewer sees.
Article 50
Article 50 of the EU AI Act is the 2 August 2026 transparency rule: labels on certain AI interactions, synthetic media, and public-interest AI text.
SynthID
SynthID is Google DeepMind's invisible watermark for AI media — a detector-readable signal in the output, not a logo in the corner.
Content credentials
Content credentials are a cryptographically signed record of who or what made a file and what was done to it, attached by a hash computed over its exact bytes — which is why the record breaks the moment those bytes change, rather than degrading gracefully.
Spark Ads
Spark Ads meaning: TikTok budget behind an existing post (yours or a creator's) so paid reach keeps the real likes, comments, and shares.
