OpenAI, the creators of ChatGPT, unveiled a new tool for users to verify whether a picture has been created using ChatGPT, OpenAI API and Codex, by tracing provenance and checking SynthId of the image.
OpenAI says it’s taking new steps to help people spot images created by artificial intelligence and build more trust online.
We’re adding new ways for people to identify AI-generated images and understand where they came from.
In addition to C2PA Content Credentials, images now also contain a SynthID watermark, and can be identified using a public verification tool to check whether an image was made…

The feature, launched on Wednesday, uses C2PA Content Credentials standards, which includes the addition of “Content Credentials” to digital media, or essentially providing a digital tag showing who created a file, how it was altered, etc. to trace ownership of the image and check for ‘SynthId’, an invisible watermarking technology that embeds the signal directly into the AI generated image.
OpenAI said the technique even works on AI images cropped, screenshot of AI images, added filters or lossy compression.
As artificial intelligence tools are on the rise, millions of people are using AI to create photos, videos and audio clips every day. But these creative and useful tools have also raised concerns about fake images, deepfakes and misinformation that can spread on social media.
As of now, OpenAI is also conducting tests of a public verification tool, where individuals can upload images and determine if they contain indicators of having been created by OpenAI AI technology. OpenAI believes that these changes will eliminate much of the confusion surrounding AI-generated content being shared on the Internet and will contribute to greater transparency as AI technology continues to become more prevalent.
