Natural Language Autoencoders are summarizers, but do they have to be?

According to LessWrong, researchers are exploring Natural Language Autoencoders — a method for interpreting AI by having models generate text explanations of their own internal neural activations. Initial tests show these explanations capture semantic content well and even transfer across different model architectures. However, the author discovers a significant limitation: the explanations confabulate, fabricating quotes and details from the original input. While the approach holds promise for auditing AI behavior, the author argues the training method requires redesign to combat these fabricated details.
