## Summary
Voluntary code supporting AI Act Article 50(2), (4) and (5): providers of generative AI systems commit to machine-readable marking and detectability of AI outputs; deployers commit to labelling deepfakes and AI-generated text published on matters of public interest, using an EU icon set. The Commission and AI Board confirmed it as an adequate tool to demonstrate compliance; about 190 organisations had signed by end July 2026.

## Why it matters
Signing is the easiest way for generative-AI providers and publishers to evidence compliance with the Article 50 labelling duties that have applied since 2 Aug 2026.
