Meta made its own AI detection system. It should have just used Google’s

Meta introduced Content Seal, an invisible watermarking system that flags images generated by its AI model to help distinguish AI-generated content from authentic images. The technology functions similarly to an already-established competitor system called SynthID, embedding hidden signals into images that remain detectable even if the image is cropped, compressed, resized, or screenshotted. Meta's Oversight Board had previously called on the company to use its own tools to combat deceptive AI content, though observers question why Meta built its own system rather than adopting existing solutions that it already collaborates with through industry standards groups.
