SynthID 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.
