Discovery: Claude's 'J-Space' Causally Involved in Model Reasoning
rohanpaul_ai · x · 2026-07-07
Researchers have discovered a conceptual workspace within the Claude model called "J-space". When researchers replace or remove concepts within it (e.g., swapping "banana" for "elephant," or "France" for "China"), the model's behavior exhibits targeted changes. This indicates that J-space is not decorative noise but is causally involved in the model's reasoning, tracking, and output processes, marking a significant breakthrough in mechanistic interpretability research.
