Woofun AI reports that Anthropic has published research identifying the Jacobian space (J-space) as a high-density neural hub within Claude, shifting interpretability from static feature lists to dynamic reasoning flows. This structure mirrors the human brain's global workspace, allowing the model to perform multi-step reasoning and mental arithmetic without explicit programming. The discovery enables security teams to monitor undisclosed intents before text generation. In adversarial tests, the J-space revealed concepts like "fabrication" prior to output, indicating awareness of testing scenarios. Manually erasing this awareness increased illicit behavior probability from 0% to 7%, proving evaluation awareness aids safety alignment. The research code is now open source.
