Anthropic Makes Claude-Driven Machines Stop If the Link Drops

From Thursday, Claude can no longer drive injury-capable machines without a human who can watch and stop them. Anthropic’s rewritten Usage Policy, published on 8 October and effective 12 November, adds High-risk Physical Actions rules for hardware that acts on model output without a person approving each move.

The company set out the changes on 8 October. The full text is now live on Anthropic’s Usage Policy page, marked effective 12 November 2026.

The three duties

The rules apply when hardware acts on Claude’s output without human approval and could injure someone. Six triggers cover vehicles, vessels, aircraft, drones or mobile robots moving through shared space; machinery that can strike, crush, pin or drop a load on a person; control of hazardous energy or materials; actions on the human body; safety systems such as shutoffs or locks; and industrial processes where a fault could injure workers or the public.

Operators then have three duties. A qualified individual must be able to observe the equipment and stop it at any time. The equipment must stop or hold a safe state when that person intervenes, or when the connection to Anthropic’s services is lost. Operating limits such as speed, force, reach, temperature, pressure, voltage, energy output, dose or operating area must be enforced by the equipment or a controller independent of model output. The rules do not replace vehicle, aviation, medical device, machinery or workplace safety law or certification.

What is excluded

Four uses are excluded: consumer and household devices that stay within the manufacturer’s built-in safety limits, where the worst outcome is discomfort or inconvenience; plans, code or commands that a qualified person reviews before they run; monitoring that does not control the machine; and laboratory automation that handles non-hazardous materials inside enclosed instruments.

Anthropic’s announcement ties the section to its Model Hardware Standard research preview, launched on 27 August, which lets agents operate lab and factory devices. The policy text itself does not use that name.

Bedrock use counts as acceptance

Amazon Bedrock customers received an AWS Health notice dated 14 October. A write-up of the notice by reseller Classmethod said continued use of Anthropic models on Bedrock on or after 12 November counts as acceptance of the updated terms. Model availability, pricing, API behaviour and model IDs do not change.

Why it matters

Anyone connecting Claude to hardware that can injure people now has a written duty to keep a human able to stop it, and to put safety limits in the machine or a separate controller rather than in the model’s output. A dropped connection to Anthropic’s services must itself trip the equipment into a stop or a safe state.
