Neural twins: models trained for each other, chatting in neuralese

repligate · x · 2026-10-30

Sauers posted a thread introducing 'neural twins': pairs of models trained specifically for each other that communicate entirely in neuralese (internal neural language). basedjensen called it 'one of the most fascinating things I have seen in a while,' and repligate amplified it. An experiment in high-bandwidth implicit inter-model communication.
