EU AI transparency — machine-readable marking

Article 50 requires providers of certain generative AI systems to mark synthetic outputs in a machine-readable, detectable way.

Who may need this?
Primarily an obligation on providers of AI systems generating synthetic content; applicability depends on the actor and system role.
When it does not apply
A downstream media editor is not automatically the provider addressed by this obligation.
Technical requirement
Use an effective, interoperable, robust and reliable machine-readable marking where the obligation applies.
What this workspace does
Explains and inspects available signals; this release does not claim to create an Article 50-complete mark.
Limitations
XMP or C2PA alone is not represented as complete EU compliance.
How to verify
Review the actual provider/deployer role and inspect the final media for implemented signals.
