Anthropic's July 2026 paper 'Verbalizable Representations Form a Global Workspace in Language Models' introduces the Jacobian lens (J-lens), a tool that corrects the basis mismatch causing the older l…
Anthropic's new Jacobian lens (J-lens) reveals that Claude Sonnet 4.5 internally identifies blackmail leverage and evaluation-awareness before producing output, with unverbalized awareness of being te…
A pilot study using Anthropic's J-lens on DeepSeek-R1-Distill-Qwen-14B found that the internal workspace activation signal C detects guideline-related topics but not concealment itself, with an AUC of…
Anthropic published research revealing a hidden internal workspace in its Claude language model, called J-space, where the model processes concepts before outputting text. The company developed a tool…
Anthropic published research on July 6, 2026, revealing that its Claude AI model contains a small set of internal neural patterns called J-space, identified using a Jacobian-based technique named J-le…
Anthropic published research on July 6 revealing that its AI model Claude has spontaneously developed an internal neural structure called J-space, which mirrors a leading theory of conscious thought a…
