OpenAI has pledged support for the European Commission’s Code of Practice on Transparency of AI‑Generated Content, a step toward enforcing the EU AI Act. The company cites provenance work that began in 2024 when it added C2PA metadata to images from DALL·E 3. Since then OpenAI layered watermarks, detection tools and a public verification site to make AI‑created media traceable globally.

OpenAI’s provenance strategy combines several signals. Images generated via ChatGPT, Codex or the API carry both C2PA credentials and its proprietary SynthID watermarks, letting metadata convey rich creation details while watermarks survive across platforms format changes. The firm joined the C2PA Steering Committee in 2024 and launched openai.com/verify, a free service that lets users confirm the presence of OpenAI provenance tags.

Provenance signals give users context for users about a piece’s origin, helping spot disinformation and protect election integrity. OpenAI says the Code’s ambition aligns with its broader EU governance roadmap, which already included signing the General‑Purpose AI Code of Practice in 2025. The company will keep refining standards, expanding verification tools, and working with regulators to keep AI‑generated content transparent.
