Anthropic Discovers Emergent 'J-Space' Global Workspace Inside Claude — A New Interpretability Breakthrough
Something remarkable has emerged inside Claude — and Anthropic didn’t put it there. On July 6, 2026, Anthropic published a new paper revealing a structure they’ve named the J-space: a small collection of internal neural patterns inside Claude models that appear to function as a kind of global workspace, broadcasting information across the model in a way that bears a striking resemblance to the brain’s own “conscious” processing. The research — produced using a new interpretability technique called the Jacobian lens (J-lens for short) — represents one of the most significant mechanistic interpretability findings to date. ...
