Anthropic has published research detailing a "J-space," an internal "global workspace" within their language models like Claude. This workspace acts as a silent, temporary memory for intermediate variables during processing, analogous to human cognition. A new tool, the Jacobian lens (J-lens), allows researchers to access and analyze this J-space, revealing that it plays a crucial role in higher-order reasoning, though it constitutes a small fraction of the model's overall activity. The J-space's existence and the J-lens's utility have been independently replicated on models like Qwen 3.6 27B, suggesting significant implications for AI interpretability and safety. AI
IMPACT Provides a new method for understanding LLM reasoning, potentially improving safety and debugging capabilities by revealing internal 'thoughts'.
