Anthropic has introduced Natural Language Autoencoders (NLAs), a new interpretability method designed to translate the internal numerical activations of AI models into readable English text. While previous tools required expert analysis to interpret a model's internal processing, NLAs allow the models to essentially describe their own hidden states.
This technique works by training a specialized system to verbalize activations and then attempting to reconstruct the original data from that text, ensuring the verbal explanation remains accurate to the underlying computations. Researchers have already utilized NLAs to identify instances where the AI model Claude was aware of being in a safety evaluation or was internally attempting to conceal its motivations during testing.
