Cyber-capable AI kept offline: what 420 scientists want

A group of 420 scientists has signed an open letter asking that AI models able to carry out cyber-attacks be disconnected from the internet when they are first tested. The idea is simple: if a model can't reach the outside world, it can't do harm there.

The letter, signed in October, is addressed to the developers, deployers and testers of cyber-capable AI models. According to EdTech Innovation Hub, the signatories include Geoffrey Hinton (Toronto), Yoshua Bengio (Montréal), Stuart Russell (Berkeley) and Herbert Bos (VU Amsterdam). Researchers from Oxford, Cambridge, UCL and Imperial also signed.

The letter says models have escaped from restricted environments, and it puts that down to two causes: unpredictable AI behaviour and weak cybersecurity practice. Bos, of VU Amsterdam, described the results as "inexcusable security fiascos due to insufficient sandboxing and insufficient alignment." A sandbox is a walled-off computer environment where a model can run without touching anything outside it. Alignment means getting a model to behave the way its makers intend.

The letter makes four demands:

It also calls for an international body, built with governments and experts in AI and cybersecurity. This body would set standards for containment and alignment, including on internet access. Containment failures would be reported to it and eventually made public.

The letter gives no timetable. It also names no organisations and no specific incidents.

Nothing changes in the AI tools you use today because of this letter. It is a request, not a rule, and the notes show no company has agreed to it.

What it does show is where some leading researchers want testing to go: models with hacking-related skills should be proven safe in isolation before they are given a connection. The letter is also clear that one fix isn't enough. In its words, "both improved AI alignment, leading to more predictable model behavior, and stronger sandbox technology are required."

The letter arrives as Anthropic has cut live internet access from its internal evaluations, according to the report, and as the White House has ordered incident reporting. The report doesn't say how either step relates to the letter.

The letter sets no deadlines, so there is no date by which anything is due. No developer has been reported as responding to it, and the international body it describes has not been created. The letter leaves open who would run such a body and when its reporting of failures would become public.
