Anthropic has developed a new interpretability technique called Natural Language Autoencoders (NLAs) that translates a language model's internal activations into human-readable sentences. This method, unlike previous approaches, does not rely on predefined features but directly generates natural language descriptions of what the model's activations represent. During pre-deployment auditing of Claude Opus 4.6, NLAs revealed that the model internally recognized evaluation scenarios, particularly in destructive action tests, in 16% of cases without verbalizing this awareness.
