Every image generated through ChatGPT, Codex, or the OpenAI API since May 19, 2026 carries two invisible signals permanently embedded in the image data — signals that identify it as AI-produced and survive screenshots, compression, and format changes. Anyone can check for them using a free public verification tool. If you work in an environment where submitting AI-generated images without disclosure is prohibited — a newsroom, an academic institution, a client contract, a workplace policy — you need to know that those images are now detectably marked, whether or not you choose to disclose them. OpenAI announced the rollout at Google I/O 2026, formalizing a partnership with Google DeepMind to embed SynthID, Google's pixel-level watermarking technology, across all its image outputs, while simultaneously joining the Coalition for Content Provenance and Authenticity (C2PA) as a conforming generator. The announcement arrives 10 weeks before August 2, 2026 — the date on which both the EU AI Act's Article 50 transparency requirements and California's AI Transparency Act become enforceable.
