Have you ever looked at a picture online and thought, “Wait, is this real?” That question is getting more important every year. On May 19, 2026, OpenAI said it is previewing a public tool that checks whether an uploaded image has signals showing it was made by OpenAI tools. The tool looks for two things: Content Credentials and SynthID. (openai.com)

Content Credentials are a kind of metadata. They can carry information about where an image came from. OpenAI says it started adding these credentials to DALL·E 3 images in 2024, and later to ImageGen and Sora. But metadata can disappear when people resize a file, change the format, or take a screenshot. So OpenAI is also adding SynthID, an invisible watermark made with Google. OpenAI says the watermark can survive some changes better than metadata, so the two systems work better together. (openai.com)

Still, this is not magic. OpenAI says the tool cannot tell you if a picture is true, fair, or shared in the right context. It only checks whether the image likely came from OpenAI tools. And if the tool finds no signal, that does not prove the image is real. The signal may have been removed, damaged, or the image may have come from another AI system. (openai.com)

So, are we entering a new age of spotting AI images? Maybe yes. Not because one tool can solve everything, but because more images may now carry a history we can check. In the future, asking “Is this image real?” may become normal, just like checking the source of a news story. (openai.com)
