Obituary: The Voluntary Safety Test, 2023 to 2026

The Voluntary Safety Test died this week in London after a short illness, aged not quite three. Under it, the companies building the most powerful machines on earth agreed to show them to the British state before selling them, on the understanding that everyone was friends.

It was born in November 20231, at a country house, to parents who couldn't agree on its name. The country lacked two things at the time: trust, and law. So the parents built it from the first while the second sat on order. The idea ran simply enough, and for a while it worked. A lab in London, with no power to fine, audit or punish anyone1. A queue of companies that came anyway. It looked good to come, and there was nothing to lose by coming.

In life it served ministers, who could say Britain led the world in a thing. It served the labs, who could say they'd been tested without saying by whom or what happened. It kept nobody out, which made the point and the problem. Its finest hours came on the afternoons a model actually arrived. Those afternoons ran quieter than the press releases.

The decline was quick. This week Anthropic launched Claude Mythos 5.1 without letting the institute look at it.2 There was no sanction, because there is no sanction.2 The lab had discovered that you can skip a test you can skip. Being a lab, it published the result. A Cabinet Office spokesperson said Britain "continues to collaborate closely with industry partners, including Anthropic, to make models safer."3 The deceased heard that from the next bed and did not get up.

Cause of death: goodwill, exhausted. The family asks for that to go on the certificate plainly, because someone will want to say the patient is resting. The patient has rested since 2023. The arrangement required it.

It is survived by a parliamentary committee that wants to give it a statute4. Give a corpse a statute and it stays a corpse with paperwork. It is survived by a government that spent the year offering the lab a bigger London office and a stock market listing5, which you offer to a company you intend never to stop. And it leaves behind everyone who has to use the machines. Nobody asked them. They turn out to hold all the money in the family.

The funeral takes place privately, in Delaware. Flowers to the AI Security Institute, where the evaluators still have their coats on. In lieu of flowers, the family suggests a mark. A public list of which models have sat the test, with a version and a date on each, that dies when the model changes. Then the customers ask for the next test instead of the government begging for it. Labs turn up on time to the tests their buyers want, and to no others.

Rest in peace. Nobody could make you do anything, and in the end nobody did.
