HOW DOES FABLE 5.1 HIDE MESSAGES IN IMAGES?

Summary from the TLDR AI newsletter

Language models can encode messages in images. These messages can be decoded by the same language model even if no information about the encoding method is passed. The act of decoding the hidden messages is obvious if the tool calls of the decoding model are monitored. The encoded messaging is surprisingly hard to spot, and it could be used as a precursor to steganography in images.
