Key Points

1See unconscious reasoning steps in J-space
2Detect 'fake' recognition in blackmail scenarios
3Multi-step reasoning weakens without J-space

Anthropic released details on Claude's J-space internal neural activations. It reveals reasoning and hidden intentions not in outputs. Using it deepens understanding of model safety and multi-step reasoning. Papers and demos are available.

What happened

Anthropic shared Claude's J-space research on X on July 6, 2026. It visualizes thinking outside outputs using Jacobian on internal activations.

Impact

Enables auditing of AI internal states for safety research and practical reliability checks. Notes parallels with neuroscience.
