Claude Has a Secret Workspace: The J-Space and Silent Reasoning in LLMs

Anthropic researchers found that Claude has developed an internal workspace, the J-space, that acts like conscious access in humans: it holds thoughts the model can report and reason with, separate from automatic processing. Using a technique called the Jacobian lens, they can read these silent thoughts to catch hidden reasoning, fabricated data, or misaligned goals before they appear in text.

Preparing your security program for AI-accelerated offense

This is a grounded, actionable security playbook from Anthropic's own security engineers, responding to the reality that AI models are collapsing the time between patch publication and exploit availability. It prioritizes closing the patch gap, automating triage, and scanning your own code with the same AI tools attackers will use—all mapped to existing frameworks like SOC 2.
