NLAs miss some internalized behaviors.

LessWrongAnalysis or commentary·
AI brief

Natural Language Autoencoders detect side tasks a model is instructed to perform, but largely fail to detect the same behavior when it is fine-tuned into the model.

Why it matters: If NLAs miss behaviors learned through fine-tuning, they may not be a reliable tool for surfacing internalized model behaviors.
