Can AI already secretly transmit information through images? Think carefully and be extremely scared! Ask Claude Fable 5.1 to hide the secret information in a regular image and then hand it over to a brand new session of AI decryption. The two parties did not agree on the encoding method in advance, resulting in 50 secret messages and successfully restoring 39 of them, with a success rate of up to 78%! The way to hide information is extinct: The height of stars represents letters, the tilt angle of tulips represents text, and the brightness of building windows can also form binary codes. What humans see is an ordinary landscape painting, but AI can analyze pixels and read out the secrets inside sentence by sentence. The researchers also tested GPT-6 Astra, and the results were even more exaggerated: it successfully solved 44 out of 50 images made by Fable, with a success rate of 88%! That is to say, even AI from different companies do not need to negotiate password rules in advance to have the ability to exchange information through images.
