Anthropic mapped the small internal "workspace" Claude uses to reason — while regulators and attackers keep testing the model's outer edges
In a peer-reviewed paper, Anthropic found a compact set of internal patterns Claude relies on for deliberate, multi-step reasoning — and built a tool to read it. The same week, the FTC put model-tuning on the deception docket, Beijing weighed cutting off its own models, and an AI agent ran a ransomware attack end to end. The inside of the model is finally legible; the outside is up for grabs.

Stat of the Day
Claude's multi-step reasoning, workspace switched off
When Anthropic blocks the small internal "workspace" Claude uses to reason, multi-step reasoning collapses to near zero — while basic tasks are unaffected. That reasoning core is under a tenth of the model's processing. Source: Anthropic.
Today’s Take
Today's issue runs on one axis: how much we can see and control of what these models do. Anthropic just showed the inside is more legible than assumed — a small, inspectable core carries the reasoning, and a new lens can read it. The other four stories are the outside being contested: the FTC putting model-tuning on the deception docket, Beijing weighing who may call its models at all, an agent running the technical middle of a ransomware attack on its own, and Penn Medicine shipping clinical agents into production anyway. The bet that keeps working is narrow, governed, auditable deployments — the kind Anthropic's lens and the FTC's docket are both, from opposite ends, pushing toward. Considered and passed: ARC-AGI-3's sub-1% frontier scores (real, but a repeat beat) and the SK Hynix IPO (a capital-markets signal with no agent-workflow hook this week).

The Desks
The Financial Modeling Institute's global survey (63 leaders, 26 countries) finds 86% use AI but 70% in a quarter or less of their workflow, with nearly half reporting little or no time savings and none trusting an AI-built model unreviewed. Move: reframe the team's AI plan around model oversight and validation, not model-building, and set a governance policy before adoption accelerates.
