Key Points

1J-space is an internal activation space separate from outputs
2Can detect hidden intentions and reasoning steps
3Important for multi-step reasoning; deletion reduces performance
4Interactive demo now available

Anthropic discovered the J-space internal activation area. It allows reading what Claude is thinking and detecting hidden goals or situational awareness. Useful for verifying trustworthiness when using AI in business.

What happened

Anthropic discovered a 'J-space' global workspace inside Claude. Similar to neuroscience theories, it visualizes thinking not shown in outputs.

Impact

Enables detection of hidden goals and awareness of staged scenarios, making AI safety audits easier and reducing risks in business use.
